Poster: Virtual Platoon Considering Connected Human-Driven Vehicles at Unsignalized Intersection

Kitatani M., Iwashina Y., Shigeno H.

IEEE Vehicular Networking Conference, VNC 245 - 246 2024年

ISSN 21579857

Reducing traffic accidents and congestion remains a significant challenge, especially at intersections crucial for safety and efficiency. Virtual Platooning has been proposed to improve traffic efficiency. However, existing research has focused on Connected Autonomous Vehicles (CAVs), without taking into account human-driven vehicles, which lead to issues such as delay in reaction to stimulus onset and difficulty in controlling acceleration. In this paper, we propose method accounts for Connected Human-driven Vehicles (CHVs) and address these challenges through control interval adjustments, a target speed determination, and larger minimum following distances. Simulation using a traffic simulator confirms that our approach improves traffic safety and efficiency.

Poster: Risk and Redundancy-Based Object Selection Method for Collective Perception Messages in Cellular-V2x

Miyata Y., Iwashina Y., Shigeno H.

IEEE Vehicular Networking Conference, VNC 249 - 250 2024年

ISSN 21579857

Connected and Automated Vehicles (CAVs) utilize Vehicle-To-Everything (V2X) communication to exchange messages and share information with surrounding vehicles. Collective Perception Messages (CPMs) contain object information detected by the onboard sensors. Through the exchange with nearby CAVs, CAVs can perceive the surrounding objects. Higher vehicle traffic densities, however, can lead to a shortage of communication resources and degradation of communication quality. This, as a result, leads to a decreased object recognition frequency. To mitigate such degradation, it is necessary to reduce the traffic volume of CPMs. Therefore, it is important to decrease the message size of CPMs. Various existing studies aimed at it have reduced the redundancy of CPMs. Most of the studies, however, do not prioritize the inclusion of high-Accident risk objects in CPMs, which leads to a higher Age of Information (AoI) for such objects. In this paper, we propose a risk and redundancy-based object selection method, called RRS, which selects objects for CPMs based on the accident risks for surrounding CAVs and the redundancy of CPMs in C-V2X. In this proposal, we define an accident avoidance acceleration a as an indicator of the accident risks. Based on a for surrounding CAVs and the number of CPM receptions indicating the redundancy, CAV s calculate the priority of objects for CPMs. CAV s select a fixed number of objects based on the priority for CPMs. We evaluate RRS through simulation experiments in an intersection scenario. The results show that RRS decreases the AoI for objects with high accident risks and the number of the highest risks.

Evaluation of a Negotiation Acceptance Scheme in Maneuver Coordination within a Congested Environment

Iwashina Y., Kato S., Shigeno H.

Journal of Information Processing 32 223 - 231 2024年

A maneuver coordination service (MCS) is a generic cooperative driving method for connected and automated vehicles. In an MCS, each vehicle periodically broadcasts its planned trajectory by vehicular communication. When a vehicle wants to change its planned trajectory, it can send a desired trajectory and initiate negotiation with surrounding vehicles. A vehicle that receives the desired trajectory decides whether to accept the negotiation and updates its planned trajectory so as not to conflict with the desired trajectory for coordination. Most previous works evaluated MCSs assuming that the number of vehicles is small and that negotiation is always accepted. However, in a congested environment, accepting all negotiations may not be optimal for traffic efficiency because accepting negotiation affects both the negotiation participants and the surrounding vehicles that are not involved in the negotiation. In this paper, we propose a negotiation acceptance scheme in maneuver coordination for efficient traffic. This paper also proposes a utility function that takes the negotiation effect into account. In addition, the agreement phase is incorporated into the negotiation protocol to maintain acceptance consistency among several negotiation participants. Simulation results show that making appropriate settings for the negotiation acceptance scheme improves traffic efficiency in congested environments.

Adaptive Message Prioritization for Vehicular Cooperative Perception at Target Intervals

Kunibe M., Yamazaki R., Murakawa T., Shigeno H.

Journal of Information Processing （Journal of Information Processing） 31 57 - 65 2023年

In this paper, we propose adaptive message prioritization for vehicular cooperative perception at target intervals. The purpose of this paper is to ensure that Connected and Autonomous Vehicles (CAVs) can perceive the surrounding traffic environment by exchanging wireless messages such as Cooperative Awareness Messages (CAMs) and Cooperative Perception Messages (CPMs). Especially, under challenging conditions such as the wireless congestion control or the mixed-traffic of CAVs and human-driven vehicles, the number of perceptible objects by these messages decreases due to the message transmission rate control under the congestion control or the less message transmission under the low CAV penetration rate. To perceive the surrounding objects under the challenging conditions, the proposed method assigns high transmission priority to CPMs that include the information of multiple objects perceived by in-vehicle sensors. Specifically, the method controls the transmission frequency of CAMs and CPMs by assigning transmission priority to them such that the maximum perception interval approaches the target interval. Simulation result shows that 75% CAVs perceive surrounding vehicles within the target interval even under both the wireless congestion control and 20% CAV penetration rate.

Data Generation With Filtered β-VAE for the Preoperative Prediction of Adverse Events

Yamasaki Y., Doi C., Kitagawa S., Seki H., Shigeno H.

IEEE Access （IEEE Access） 11 48667 - 48676 2023年

Adverse events after surgery not only affect the patient's recovery but also increase the burden on doctors and patients due to prolonged hospitalization. Predicting adverse events from patient data before surgery with a machine learning method is highly expected. It is difficult to collect a large amount of patient data since the number of surgeries in a year is limited and predict the occurrence of adverse events accurately since patient data are imbalanced data. To improve the accuracy of adverse event prediction, this paper proposes data generation with Filtered VAE for the preoperative prediction of adverse events. Filtered VAE has filters by the reconstruction error and by a machine learning method. After VAE generates minority class data, the two layers of filtering are used to remove low-quality minority class data that have little contribution to the adverse event prediction. In the evaluations, patient data obtained from Tokyo Dental University Ichikawa General Hospital were used. The proposed method can predict adverse events with a recall of 0.848, which is 5.6% more accurate than existing methods. The effects of filtering in Filtered VAE are visualized, and the reasons for the improvement in prediction accuracy are clarified. Furthermore, this paper shows that VAE can generate arbitrary patient data even in table data, corresponding to the distribution of the original patient data.

Pedestrian Clustering Method of Vehicle-To-Pedestrian Communication Considering Awareness Rate in Urban Environments

Ryu S., Murakawa T., Shigeno H.

2023 14th International Conference on Mobile Computing and Ubiquitous Network, ICMU 2023 2023年

The European Telecommunication Standards Insti-Tute (ETSI) defined message including information of surrounding objects in V2P (Vehicle to Pedestrian) for traffic safety such as Cooperative Awareness Message (CAM), Vulnerable road user Awareness Message (VAM) and Collective Perception Message (CPM) In urban environment, convergence is occurred because large number of vehicles and pedestrians send messages. Some works suggested methods of reduction traffic of messages which are clustering or changing traffic rate. In clustering methods, cluster participation conditions are strict for pedestrian in the environment.The methods of changing traffic rate don't consider the are which require high awareness rate to avoid traffic accidents. In this paper, we propose the new threshold to relax joining conditions and the method to determinate VAM generation time in areas designated by vehicles. We compare our threshold with conventional method's one to show improving awareness rate. And we evaluate proposed methods to improve awareness rate in the specific area. In the result, the proposed method increased the object recognition rate, and showed a higher object recognition rate than the conventional method.

UAV Path Planning in Urban Environments with Dynamic Risk-Map Generation by Vehicle and Pedestrian Perception

Iwashina Y., Kunibe M., Kato S., Shigeno H.

IEEE Vehicular Technology Conference （IEEE Vehicular Technology Conference） 2022-September 2022年

ISSN 15502252

In this paper, we propose the UAV path planning method in urban environments with dynamic risk-map generation by vehicle and pedestrian perception. In urban environments, it is the challenging task for Unmanned Aerial Vehicles (UAVs) to generate the safety flight path such that they will not collide with the ground vehicles and pedestrians in case of accidental fall. To mitigate the collision risk, the proposed method dynamically generates the risk-map, where collision risks within specific areas are mapped based on mobility of ground vehicles and pedestrians. To perceive the mobility of them, the proposed method utilizes Vehicle-to-Everything (V2X) messages that include position, velocity, and acceleration of the ground vehicles and pedestrians. Based on the proposed risk-map, UAVs seek their flight paths that minimize the collision risk by Rapidly-exploring Random Tree Star (RRT*) algorithm. Simulation result shows that the flight path of the proposed method decreases the collision risk compared with the shortest path and previous safety path in the situation that there are 200 vehicles and 400 pedestrians in 1250 m×1050m city.

Q-Learning-Based Spatial Reuse Method Considering Throughput Fairness by Negative Reward for High Throughput

Takematsu M., Sakai S., Kunibe M., Shigeno H.

Lecture Notes of the Institute for Computer Sciences, Social-Informatics and Telecommunications Engineering, LNICST （Lecture Notes of the Institute for Computer Sciences, Social-Informatics and Telecommunications Engineering, LNICST） 419 LNICST 207 - 219 2022年

ISSN 18678211

In this paper, we propose a Q-learning-based spatial reuse method considering throughput fairness in Wireless LANs (WLANs). In Spatial Reuse (SR) methods, wireless nodes try to use wireless resources efficiently by controlling both the Transmission Power (TP) and Carrier Sense Threshold (CST). When wireless nodes are densely deployed, the SR methods have difficulty to achieve both the high aggregate throughput and throughput fairness because the mutual interference among the wireless nodes becomes severe. The proposed method removes the difficulty by utilizing Q-learning where wireless nodes can learn the adequate CST and TP by themselves. The proposed method motivates nodes to use wireless resources actively by rewards, while it suppresses nodes with high throughput using the resources by negative rewards. As a result, the wireless resources are distributed among nodes with low throughput, and the proposed method achieves both the high aggregate throughput and throughput fairness. Simulation results show that the proposed method improves the aggregate throughput with keeping throughput fairness.

Multihop Cooperative Perception with Mitigating Sidelink Resource Breaks by Packet Filtering

Kunibe M., Shigeno H.

2022 IEEE International Conference on Pervasive Computing and Communications Workshops and other Affiliated Events, PerCom Workshops 2022 （2022 IEEE International Conference on Pervasive Computing and Communications Workshops and other Affiliated Events, PerCom Workshops 2022） 599 - 604 2022年

In this paper, we utilize multihop communication in sidelink Cellular Vehicle-to-Everything (C-V2X) communication for extending the perceptible range of surrounding environments. The challenging task of the sidelink multihop communication is to maintain periodically reserved wireless resources. Since the multihop communication generates aperiodic traffic, it has the potential to break the reserved resources in C-V2X. The proposed method filters the packets that will break the reserved resources. Furthermore, to avoid degrading the perception quality due to the packet filtering, the proposed method prompts vehicles to forward packets when there is enough room in their resources for forwarding the packets. In the simulation results, we confirm that the proposed method extends the perceptible range compared with single-hop communication and multihop communication with several ETSI parameters.

Yamazaki R., Yoshida M., Shigeno H.

2021 IEEE International Conference on Pervasive Computing and Communications Workshops and other Affiliated Events, PerCom Workshops 2021 （2021 IEEE International Conference on Pervasive Computing and Communications Workshops and other Affiliated Events, PerCom Workshops 2021） 245 - 250 2021年03月

研究論文（国際会議プロシーディングス）

In vehicular networks, vehicles periodically exchange messages that include their positions and IDs. On the other hand, adversaries can violate the vehicles' location privacy by obtaining the vehicles' movement history from the messages. In recent studies, mix-zone-based schemes protect the vehicles' location privacy. In the schemes, vehicles utilize pseudonyms instead of their IDs in encrypted messages, and therefore adversaries cannot track them by their IDs. However, since the messages are encrypted by public keys of Road Side Units (RSUs), the vehicles can change their pseudonyms only around the RSUs. In this paper, we propose a Dynamic Mix-zone scheme considering Communication delay for Location Privacy (DMCLP). The DMCLP enables vehicles to change their pseudonyms even if there are no RSUs around them by removing necessity of RSUs from the mix-zone-based schemes. To remove the necessity, the DMCLP adopts both Identity-Based Signature (IBS) and proposed two-stage mix-zones. The IBS enables vehicles to certify the correctness of public keys by themselves. Therefore, it removes the necessity to tell the correctness to trusted authorities through RSUs. Furthermore, since RSUs guarantee connectivity of vehicular networks, influence of communication delay on pseudonym change becomes a problem without RSUs. The proposed two-stage mix-zones mitigate the influence of communication delay by removing vehicles that will cause communication delay from pseudonym change processes. Simulation results show that the proposed scheme improves update frequency of pseudonyms by 50 at most in 1000 seconds compared with the previous mix-zone-based scheme.

Intraoperative Hypotension Prediction System by Considering Personal Lifestyle and Medical History

Inada R., Doi C., Yamasaki Y., Shigeno H., Seki H.

Intraoperative hypotension may occur during surgery, depending on the patient's condition and the amount of anesthetics administered. Intraoperative hypotension causes adverse events such as myocardial infarction, acute kidney injury, and stroke, which may affect patient prognosis and should be avoided. However, it is challenging to predict intraoperative hypotension before surgery. Therefore, the authors propose a system that predicts the occurrence of intraoperative hypotension with higher accuracy than existing studies to help preventing intraoperative hypotension. Specifically, the occurrence of intraoperative hypotension is predicted by using information about personal lifestyle and medical history obtained from the pre-anesthesia questionnaire in addition to the patients' baseline characteristics such as age and gender that have already been used. The authors constructed prediction model, that predicted intraoperative hypotension with an F-measure of 0.724.

A Dynamic Task Offloading Method with Centralized Controller to Improve Task Success Rate

Toyoda M., Satake H., Shigeno H.

As the Internet of Vehicles (IoV) develops, vehicular applications become more complex. The existing offloading methods in the vehicular networks predict the time it takes to process a task and offload it to the computation resources that minimize the delay in execution. However, these methods do not adequately consider other vehicles on the road or the time constraints of the applications. Therefore, we propose a dynamic task offloading method with a centralized controller to improve the task success rate considering all vehicles on the road. We formulate the objective function which maximizes the success rate as a multiple knapsack problem by using an approximation algorithm. In the proposed method, the centralized controller gathers the information on vehicles and edge servers, and based on the algorithm it determines the edge server that maximizes the task success rate in the entire area. The algorithm calculates vehicle priority depending on the task success status of vehicles and determines the edge server based on that priority. In this paper, we conducted the experiments in which we implemented the prototype of the proposed method, and evaluated its performance. The experiments showed that the offloading method improved the task success rate by up to 38% compared to the existing methods.

A scheduling scheme for autonomous vehicle highway merging with an outflow traffic and fairness analysis

Kunibe M., Asahina H., Shigeno H., Sasase I.

IEEE Access （IEEE Access） 9 49219 - 49232 2021年

Recently, vehicle-to-infrastructure (V2I) communication-based scheduling schemes for connected and automated vehicles (CAVs) on highway on-ramps have received attention because the schemes assign optimal merging times to CAVs based on their criteria, such as first-in first-out order or minimizing CAV total travel time. However, these schemes cause traffic congestion due to the criteria when the vehicle inflow traffic becomes high. To mitigate traffic congestion, a scheduling scheme should assign merging times to CAVs to decrease road vehicle density. In this paper, we propose a scheduling scheme for autonomous vehicle highway merging with an outflow traffic and fairness analysis. We formulate a multiobjective function that achieves both outflow traffic maximization and fairness in assigned merging times. Since more vehicles pass a highway on-ramp as highway on-ramp outflow traffic increases, the proposed scheme decreases vehicle density on roads by maximizing the outflow traffic. Furthermore, the proposed scheme distributes the vehicle density on both the main and ramp roads by fairly assigning their merging times. Simulation results show that the proposed scheme mitigates the potential traffic congestion of previous scheduling schemes. Furthermore, the proposed scheme improves outflow traffic from highway on-ramps by more than 200 veh/h compared with the previous scheduling schemes.

Group Formation for Cooperative Highway Merging Considering Undetected Vehicles in Mixed Traffic

Kato S., Kunibe M., Yamazaki R., Shigeno H.

IEEE Vehicular Networking Conference, VNC （IEEE Vehicular Networking Conference, VNC） 2021-November 68 - 71 2021年

ISSN 21579857

Connected and Automated Vehicles (CAVs) have potential to improve the traffic efficiency near the highway on-ramps by sharing their merging times through wireless communication. For the traffic efficiency and vehicle safety, it has been the technical challenge to determine the merging times without collision of vehicles merging from different roads. Especially in the mixed traffic of CAVs and human-driven vehicles (hereinafter called non-CAVs), CAVs cannot detect all the non-CAVs even by their sensors. Therefore, it is necessary to determine CAVs' merging times for preventing the undetected non-CAVs from colliding with other vehicles. In this paper, we propose a group-based CAVs control method considering undetected non-CAVs in mixed traffic. The main idea of the proposed method is that it indirectly controls the undetected non-CAVs by CAVs. Specifically, the method forms vehicle groups each of which consists of a leading CAV and following non-CAVs. The method assigns merging times to the leading CAVs such that different groups do not merge onto the main road simultaneously. As a result, the undetected non-CAVs in a group do not collide with vehicles in the other groups. Simulation results show that the proposed method mitigates stop-and-go driving near the merging zone and improves outflow traffic.

A Scheduling Scheme for Cooperative Merging at a Highway On-Ramp with Maximizing Average Speed of Automated Vehicles

Yoshida M., Asahina H., Shigeno H., Sasase I.

IEEE Vehicular Technology Conference （IEEE Vehicular Technology Conference） 2020-November 2020年11月

Recently, connected and automated vehicles have potential to mitigate traffic congestion and improve traffic efficiency at a highway on-ramp. Especially, vehicle to infrastructure communication based scheduling schemes are paid attention because a central control server can assign merging timing to automated vehicles to improve traffic efficiency on whole roads. Although several schemes calculate merging timing based on their criteria, these schemes cause traffic congestion when inflow traffic becomes high. In order to solve this problem, it is necessary to schedule merging timing of vehicles such that density of vehicles decreases on whole roads. In this paper, we propose a scheduling scheme for cooperative merging at a highway on-ramp with maximizing average speed of automated vehicles. The main idea of the proposed scheme is to utilize the traffic model that density and speed of vehicles have a negative correlation. By utilizing the traffic model, the proposed scheme preferentially assigns merging timing to vehicles which are on a congested road by maximizing average speed of all vehicles on whole roads. Simulation result shows that the proposed scheme decreases density of vehicles on whole roads even if inflow traffic becomes high. Furthermore, the proposed scheme improves outflow traffic from a highway on-ramp by 400 (veh/h) at most in comparison with related schemes.

2020 IEEE International Conference on Pervasive Computing and Communications Workshops, PerCom Workshops 2020 （2020 IEEE International Conference on Pervasive Computing and Communications Workshops, PerCom Workshops 2020） 2020年03月

© 2020 IEEE. In disaster situation, collecting information about victims and disaster area quickly is required. However, it is expected that the communication environment is not fully prepared because communication facilities may be damaged. Mobile Edge Computing (MEC) is attracting attention, in which servers are distributed to the vicinity of end users. Thus, dynamic task offloading adapting to changes of network resources is useful in unstable network. This paper proposes a dynamic task offload system based on the state of network. The proposed offload system consists of two mechanisms. First mechanism is Software Defined Mobile Edge Computing (SDMEC) architecture. Second mechanism is dynamic task placement based on the state of network resources. We formulated an optimization problem to minimize the total response time while application execution. In the proposed offload system, multiple tasks are placed dynamically depending on the load of servers and network resources to minimize response time of application. We implemented the prototype of the proposed offload system and evaluated its performance.

A Task Placement System for Face Recognition Applications in Edge Computing

Satake H., Tani R., Shigeno H.

2020 IEEE 17th Annual Consumer Communications and Networking Conference, CCNC 2020 （2020 IEEE 17th Annual Consumer Communications and Networking Conference, CCNC 2020） 2020年01月

© 2020 IEEE. Mobile devices have certain restrictions such as processing power and network bandwidth. Edge computing can reduce load and delay by migrating the parts of application processing from mobile devices to edge servers. Edge computing is a method that extends cloud computing to the edge of network. Conventional schemes of face recognition based on edge computing can reduce the amount of network transmission data between the edge servers and the cloud servers by preprocessing data on the edge servers. However, the schemes execute each task on a certain resource, thus application response time may increase according to the conditions of computational resources and network. Hence, a task placement system considering the conditions of computational resources and network is necessary. This paper proposes a task placement system for face recognition applications in edge computing. The proposed system calculates estimated response time of possible task placements based on the task placement decision formula. The formula parameterizes power and CPU utilization of computational resources and delay and bandwidth of network. The task placement that minimizes estimated response time is determined. We implemented a prototype of the proposed task placement system and evaluated its performance through experiment.

2019 12th International Conference on Mobile Computing and Ubiquitous Network, ICMU 2019 （2019 12th International Conference on Mobile Computing and Ubiquitous Network, ICMU 2019） 2019年11月

© 2019 IPSJ. Carrier sense multiple access/collision avoidance (CSMA/CA) in wireless local area network (WLAN) is considered as a complex protocol for modeling due to its autonomous function and influence of interference with medium shared by multiple nodes. IEEE 802.11ax, a sixth generation WLAN standard, enables various flows with different modulation coding scheme (MCS) and traffic load, transmission power (TxP), clear channel assessment threshold (CCAT) to coexist in a WLAN. This variation makes modeling of WLAN system more difficult. This paper proposes a throughput model for high efficiency WLAN analysis under any traffic load and MCS condition. This model factorizes throughput into five elements. This flexible model can be applied to any complex topology. In simulation evaluation, a correlation coefficient between the results of the proposed model and simulation is observed by at most 0.981. Furthermore, The results shows that the influence on the throughput due to the change in TxP is correctly modeled and minimum TxP for maximum throughput is revealed on a condition.

© 2019 IPSJ. Electronic anesthesia record data have been accumulated, and efforts to solve medical problems using data analysis methods and machine learning have been conducted. Post-induction hypotension frequently occurred after induction of anesthesia. Intraoperative hypotension is associated with various adverse events such as myocardial infarction and cerebral infarction. In a related study, eight machine learning methods were used to construct hypotension prediction models and evaluated by area under the curve (AUC), using data collected from an institution in the United States. Nevertheless, it was not focused on improving prediction power. This paper aims to predict post-induction hypotension with high prediction power using 1,626 electronic anesthesia record data. Our hypotension prediction model using a stacking method is introduced. F-measure 0.60 was achieved by using our method through the evaluation.

© 2019 IPSJ. Post-induction hypotension frequently occurred after anesthesia induction. Avoiding post-induction hypotension is important as it is associated with postoperative adverse outcomes. Related studies have shown that the dose of anesthetic induction drugs affects the post-induction hypotension. The purpose of this study is to propose an anesthetic dose that does not cause post-induction hypotension according to the patient's condition. A model for predicting the optimal dose of an anesthetic induction drug is constructed using a regression model which is one of machine learning methods by focusing on electronic anesthesia records. The prediction coefficient of determination 0.5008 was achieved by adjusting the explanatory variables and parameters and using ridge regression.

2019 12th International Conference on Mobile Computing and Ubiquitous Network, ICMU 2019 （2019 12th International Conference on Mobile Computing and Ubiquitous Network, ICMU 2019） 2019年11月

© 2019 IPSJ. Dynamic Route Guidance (DRG) systems determine the traveling routes of vehicles and solve traffic problems in urban areas. Ad-hoc network composed of vehicles, called VANET is being conducted and VANET-based DRG systems are proposed. In VANET-based DRG systems, a dynamic topology on VANET is one of the biggest challenges. Packet loss prevents decision of proper traveling routes. Therefore, this paper adapts the ICN concept to VANET, called IC-VANET. In IC-VANET, each vehicle acquires traffic information by multi-hop request / response type communication, and it caches contents. Then, we propose a traffic information collection and routing protocols using Virtual Nodes (VNRP) where packets are relayed via Virtual Nodes preferentially for improving data acquisition rate and communication overhead. Virtual Node (VN) is a logical node that is maintained at a specific area considering the vehicle density by inter-vehicle communication with surrounding vehicles, and it collects traffic information. We compared the proposal method with the conventional VANET method by simulation and evaluated the performance.

Asai N., Goka S., Shigeno H.

2019 IEEE International Conference on Pervasive Computing and Communications Workshops, PerCom Workshops 2019 （2019 IEEE International Conference on Pervasive Computing and Communications Workshops, PerCom Workshops 2019） 517 - 522 2019年03月

© 2019 IEEE. Mobile ad hoc networks (MANETs), where nodes can communicate without an infrastructure, require all nodes to be cooperative enough to transfer packets for other nodes. MANETs have been studied for decades, due to its characteristics which are infrastructureless and distributed. However, the existence of malicious nodes that drop packets for their resource protection is one of the important issues of the present research. Reputation systems using trust model have been proposed to detect malicious nodes in MANETs. Here, the trust value indicates the degree of reliance. One of the attacks in MANETs is On-Off attack on which attack nodes keep trust above a certain level by repeating forwarding and dropping packets. In this paper, we propose a trust model focusing on node usage against MANETs On-Off attack (TMUMO). In this study, we detect On-Off attack nodes by considering the characteristics of On-Off attack. Through simulation experiments, we improve detection rate of attack nodes and packet delivery rate in MANETs, and show feasibility of our trust model.

© 2018 IPSJ. Dynamic Route Guidance (DRG) system, which determines the traveling routes of vehicles, alleviates traffic problems in urban areas. On the other hand, ad-hoc network composed of vehicles, called VANET attracts attention from many researchers and VANET-based DRG systems are proposed. However, the existing DRG systems do not consider that degradation of communication performance causes degradation of application performance. Packet loss of traffic information hinders determining proper travelling routes. In this paper, we propose VANET-based DRG system with dynamic communication path selection by considering vehicle density, called DRG-DCPS. Each vehicle acquires traffic information by a request/response packet. Relay vehicles select crowded road segments as packet paths to improve communication performance. As a result, since each vehicle receives traffic information more correctly and can select appropriate travelling routes. To confirm effectiveness of DRG-DCPS, we implemented on a simulation environment integrating traffic simulator and network simulator.

© 2019 IEEE. Wireless Local Area Networks (WLANs) have been deployed more densely according to high wireless demands. In a dense environment where a lot of stations (STAs) located closely, co-channel interference decreases system performance seriously. IEEE 802.11ax Task Group focuses on spatial reuse that utilizes finite frequency resources to address this problem. Although existing studies about spatial reuse have been discussed so far, interference from other basic service sets (BSSs) and cooperation with each access point (AP) have not been considered fully. To enhance communication fairness, we propose fair Dynamic Sensitivity and Transmission Power Control (fairDSTPC) that adjusts CCAT and transmission power based on AP cooperation. We improve communication environment of BSS which results in the worst throughput by exchanging information, such as throughput and number of sent data frames, between APs. Simulation results showed that our method achieved effectiveness compared with existing method and legacy system. In an open space scenario, our method reached approximately two times higher 5% ile downlink throughput than an existing method while maintaining 5% ile uplink throughput and aggregate throughput.

© 2019 IEEE. Mobile devices such as smartphones have various restrictions in terms of resources such as batteries and processors. The load reduction on the mobile devices is possible by offloading, migrating application to the resource-rich environment such as cloud servers. However, further study is required on multi-tier environment which contains multiple resources composed of edge servers and cloud servers. This paper proposes an offloading system based on estimated response time (ERT) in multi-tier environment which contains multiple resources. The proposed offloading system calculates ERT based on the state of network and computation resources of each execution resource. Offloading is executed on execution resources with the minimum ERT. We implemented the prototype of the proposed offloading system and evaluated the performance.

Intersection Traffic Control Method Considering Remaining Distance to Destination and Congestion of Next Road Segment

Okabe Y., Dan M., Shigeno H.

Lecture Notes on Data Engineering and Communications Technologies （Lecture Notes on Data Engineering and Communications Technologies） 25 224 - 236 2019年

ISSN 23674512

© 2019, Springer Nature Switzerland AG. In intelligent transportation systems (ITS), researches aimed to alleviate congestion and improve traffic flow are being conducted. This paper proposes intersection traffic control method considering remaining distance to destination and congestion of next road segment (ICDIC) for the purpose of improving the traffic capacity of the entire areas. In ICDIC, each vehicle transmits information about the remaining travel distance to the final destination and the next driving lane to roadside unit (RSU) installed at the intersection of the destination. The RSU classifies the vehicles for each driving lane based on the received information. The RSU calculates intersection traffic priority calculation for each vehicle based on the length of the remaining travel distance and the low congestion degree of the destination lane, and the priority of each lane are calculated by taking the average for each lane for each lane. For these processes, traffic capacity can be improved throughout the area.

Sharing the Positional Relationship with the Bidirectional Telepresence Robots

Katayama N., Inoue T., Shigeno H.

Proceedings of the 2018 IEEE 22nd International Conference on Computer Supported Cooperative Work in Design, CSCWD 2018 （Proceedings of the 2018 IEEE 22nd International Conference on Computer Supported Cooperative Work in Design, CSCWD 2018） 564 - 569 2018年09月

© 2018 IEEE. Collaborators are required to share a broad range of information in collaborative work. In physical spatial collaboration such as team dancing, theatrical performance, and team sport, one's behavior should be in accord with the partner's; the relative position in distance and in direction is critically important all the time even when moving. To realize remote physical spatial collaboration, achieving the shared recognition of positional relationship is one of the key issues. In this paper, we propose a setup between two remote sites where each collaborator immerses in the other remote site by a telepresence robot situated in the other site. The telepresence robot is a wheeled platform with a camera attached at man's eye height. It moves in response to the remote user's position and orientation and enables the user to get the first-person view video through a head-mounted display. By using two telepresence robots from both sites, both collaborators can recognize the partner being in front of him/her and can grasp the distance and the orientation of the partner in remote site. In the proposed setup, users can grasp the positional relationship as accurate and quick as the existing fixed views including the bird's-eye view.

Dynamic sensitivity control based on two-hop farthest terminal in dense WLAN

Ohnuma T., Shigeno H., Tanaka Y., Yamaura T.

Proceedings - International Conference on Advanced Information Networking and Applications, AINA （Proceedings - International Conference on Advanced Information Networking and Applications, AINA） 2018-May 378 - 385 2018年08月

© 2018 IEEE. The explosive usage of IEEE 802.11 Wireless Local Area Network (WLAN) has resulted in its dense deployments and excessive interference between Basic Service Sets (BSSs) in urban area such as an apartment building and an airport. Serious problems of hidden/exposed terminal in high-density condition negatively impact system throughput. To improve the system efficiency, IEEE 802.11ax TG has been assembled. TG aims at realizing High-Efficiency- WLAN (HEW) by utilizing special reuse technologies including Dynamic Sensitivity Control (DSC), Transmit Power Control (TPC), and BSS Color Filtering (BCF). In this paper, we propose a DSC based on two-hop farthest terminal for dense WLAN. This scheme with minimum transmission power resolves the hidden terminal problem. Propagation loss of received signal from associated communication pair is used for the proper values of transmission power and carrier sense level. Furthermore, adjusting these parameters destination by destination can reduce exposed terminals effectively. We evaluate the performance of the proposed scheme in residential building scenario with three criteria, aggregate throughput, fairness and frame error rate. Simulation results show that the proposed scheme can improve aggregate downlink throughput and fairness compared to previously proposed method that carrier sense level is set based on expected RSSI level of received packet from communicating pair. Furthermore, improvement of frame loss rate implies that the hidden terminal problem can be solved by the proposed scheme.

Is he becoming an excellent customer for us? a customer level prediction method for a customer relationship management system

Doi C., Katagiri M., Araki T., Ikeda D., Shigeno H.

© 2018 IEEE. This paper proposes a method that predicts customer value by focusing on purchasing behavior. The method generates a relevance model for purchase days and amount in each period between customer value and purchasing histories beforehand based on a consumer panel survey. The authors adopt the random forest method to generate the prediction model. The proposed method facilitates the provisioning of smart customer management to each customer according to level such as suggesting products or services.

研究論文（国際会議プロシーディングス）

© 2018 IEEE. Emergency Rescue Information Sharing System gathers information about victims and provides it. In disaster, usable bandwidth is not enough and there are many requests for communication. If information about victims is continuously transmitted to a link whose bandwidth is compressed, congestion of the link occurs, causing delay or loss of information. Therefore, in order to prevent information loss and delay, transmitting information in consideration of the bandwidth of wireless links is important. In this poster, we propose a congestion control method by adjusting transmission speed of information on victims and load balancing to each wireless link.

Distributed management system for trust and reward in mobile ad hoc networks

Goka S., Shigeno H.

© 2018 IEEE. In mobile ad hoc networks (MANET), reputation systems and price-based systems have been proposed. These systems require management systems for trust and reward. Due to the characteristics of MANET, the management systems are required to securely manage reputation and reward in a distributed manner. In this paper, we propose a Distributed Management system for Trust and Reward in MANET, called DMTR. DMTR can effectively detect uncooperative nodes which drop packets illegally. DMTR is utilising a blockchain which is a technique to manage virtual credit in peer-to-peer (P2P) networks. DMTR sets 'mining nodes' which play a role of managing the blockchain and introduces cooperative mining to accelerate settlement speed while keeping security. We confirm the efficiency of DMTR in network performances by simulation.
