Poster: Multi-Agent Transformer for Dynamic Allocation of Distributed Applications on the Edge

IEEE Vehicular Networking Conference, VNC 255 - 256 2024
Edge computing has to potential to deliver vital low-latency services for ITS. However, due to the limited resources available on the edge, carefully allocating such services and adapting to changes in client distribution is necessary. In this poster, we show that a MAT reinforcement learning approach can perform better than heuristics.

The purpose of this research is to share pedestrian information among multiple vehicles by vehicle-to-vehicle communication and detect the positions of all pedestrians around the vehicle. In the past, we have proposed a method of collating shared pedestrian information through image-based person Re-Identification (ReID). In this paper, in order to improve the accuracy of pedestrian information collation, the state-of-the-art ReID network is adapted to our scenario by fine-tuning. In addition, a new pedestrian image dataset for sharing pedestrian information was constructed. In our experiments using our dataset, the proposed method improved the pedestrian information collation accuracy.

Radio resource allocation based on adaptive and maximum reuse distance for LTE-V2X sidelink mode 3 Reviewed

LTE-V2X is one of the promising wireless technologies for Vehicle to Everything (V2X), which is expected to enhance the safety of road traffic. In this paper, we propose a radio resource allocation scheme for LTE-V2X Sidelink Mode 3. The reliability of packet transmission is seriously affected by changes in vehicle density. To cope with this issue, our new scheme reuses radio resources efficiently by calculating the range of protection from mutual interference based on the vehicle density. Compared with existing schemes, the proposed scheme successfully maintains a lower error rate of packet transmission regardless of the vehicle density.

Indoor localization based on CSI in dynamic environments through domain adaptation Reviewed
Liuyi Yang, Tomio Kamada, Chikara Ohta
IEICE COMMUNICATIONS EXPRESS 10 ( 8 ) 564 - 569 2021
Publisher：IEICE-INST ELECTRONICS INFORMATION COMMUNICATIONS ENG
As the demand for indoor localization applications continues to grow, device-free localization based on Wi-Fi Channel State Information (CSI) has become a popular research topic. Wi-Fi signals are, however, easily affected by environmental factors such as furniture changes. These factors disable the original localization system, and rebuilding it will cost a lot of time and workforce. This is a major challenge of device-free Wi-Fi localization. To address this issue, we use a transfer learning method, "Integration of Global and Local Metrics for Domain Adaptation (IGLDA)," and improve it, aiming to adapt the original localization model to the changing environment. Consequently, the localization accuracy is improved from 26.3 % to 82.2 % by only recollecting 37.5 % of data.

Distributed topic management in publish-process-subscribe systems on edge-servers for real-time notification service Reviewed

Publisher：Institute of Electronics, Information and Communications Engineers ({IEICE})
The importance of real-time and data-driven notification has been growing for social services and Intelligent Transporting System (ITS). As an advanced version of Pub/Sub systems, publish-process-subscribe systems with MEC (Multi-access Edge Computing), where published messages are spooled and processed on edge servers, have been proposed. In this paper, we present a topic-based publish-process-subscribe system that allows a topic to be managed on multiple edge servers so that messages are processed near publishers and transferred to subscribers immediately. However, managing each topic on numerous edge servers can cause exhaustion of storage resources on edge servers. We introduce a simple topic allocation method on edge servers to discuss the problem. Experiments show the feasibility of our proposed system.
