Felipe Valle, Daniel Bleckert, Linus Frisk, Oscar Amador, Molina, Elena Haller, Alexey Vinel

TL;DR
This paper introduces a non-negotiated, resilient clustering method for VRU messages in C-ITS that reduces network load and maintains awareness despite lossy communication channels.
Contribution
It proposes a novel non-negotiated clustering scheme for VRU messages that operates without extra communication and handles lossy channels, improving network efficiency.
Findings
Halves message generation compared to individual messaging.
Maintains VRU awareness levels despite lossy channels.
Operates without negotiation or extra message overhead.
Abstract
Including Vulnerable Road User (VRU) in Cooperative Intelligent Transport Systems (C-ITS) framework aims to increase road safety. However, this approach implies a massive increase of network nodes and thus is vulnerable to medium capacity issues, e.g., contention, congestion, resource scheduling. Implementing cluster schemes -- to reduce the number of nodes but represent the same number of VRUs -- is a direct way to address the issue. One of them is suggested by European Telecommunications Standards Institute (ETSI) and consists of nodes (connected pedestrians and cyclists) sending vicarious messages to enable a leader node to cover for a cluster of VRUs. However, the proposed scheme includes negotiation to establish a cluster, and in-cluster communication to maintain it, requiring extra messages of variable sizes and thus does not fully resolve the original medium capacity issues.…
