A probabilistic convergecast protocol for vehicle to infrastructure communication in ITS architecture

Abstract

The Virtual Police Agents for ITS Traffic routing (VPAIR) is a proposal of an Intelligent Transport System (ITS) architecture affordable in terms of cost, maintenance and operation, in addition to guidelines respectful of ITS America. Despite its numerous advantages, this architecture doesn't embed a routing protocol for vehicles, in sparse network who suffers from high delay and frequent connectivity disruption. In our current work we propose PRobabilistic ConvergeCast (PRoCC) as a routing protocol dedicated to Vehicle to Infrastructure (V2I) communication in sparse network. The protocol is inspired by the convergecast routing scheme and Delay Tolerant Network (DTN). Simulation results show honorable performance when compared to well-known DTN protocols like the Routing Protocol using History of Encounters and Transitivity (PRoPHET).
