• Preamble Arbitration Rule and Interference Suppression-Based Polling Medium Access Control for In-Vehicle Ultra-Wideband Networks

  Makoto Okuhara, Nobuyuki Kurioka, Shigeki Mitoh, Patrick Finnerty, Chikara Ohta

  This paper introduces a preamble arbitration rule and interference suppression (PARIS) method for ultra- wideband (UWB) in-vehicle networks. Advancements in the automotive technology have led to increased reliance on wire harnesses, resulting in higher costs, electronic integration challenges, and adverse environmental effects. To address these problems, we explored the use of UWB wireless networks, which are characterized by low transmission power and superior signal penetration capabilities. A significant challenge associated with implementing UWB in automotive environments is the increased frame error rate (FER) caused by UWB interference. Our experiments indicate that vehicles equipped with identical UWB networks exhibit an FER of approximately 6 % when positioned closely. This level of FER is problematic for automotive applications, where reliable communication is paramount. To mitigate this problem, we developed an PARIS communication algorithm that is robust against interference. As identified in this study, PARIS leverages two key characteristics of UWB. First, it prioritizes the timing of signal reception over radio signal power, enhancing interference suppression by activating the receiver at the optimal moment before the desired frame arrives, thereby minimizing data loss. Second, the algorithm exploits the hierarchical nature of preamble codes in simultaneously received frames, reducing data loss rate to the order of 10−5 by prioritizing frames from critical communication devices based on the preamble code hierarchy. Implementing the UWB-based PARIS method in wireless vehicle networks can reduce the weight of the wire harnesses by approximately 20 %, offering a promising solution to the challenges posed by traditional wiring systems.

• Pedestrian Information Collation through Image-Based Person Identification for Pedestrian Information Sharing using V2V Communications.

  Naoko Enami, Saai Uemura, Koh Asano, Patrick Finnerty, Tomio Kamada, Chikara Ohta

  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.

  This research aims to provide distributed collection libraries for many-core large-scale clusters and enables dynamic load-balancing over them. We developed (1) a self-adjusting task granularity mechanism for our global load balancer library to avoid contention on many‐core clusters and (2) a series of relocatable distributed collections featuring inter/intra-node parallelism. For integrating load-balancer and distributed collections, we developed (3a) a global load balancer for distributed arrays involving range-based element relocation. In addition, we developed (3b) a distributed cell set that allows the easy description of communication/computation overlapping and relationships between inter-node communication and its dependent computations.
