Abstract: A
MANET (Mobile Ad hoc Network) which ensures wireless connections between
cars/vehicles is called Vehicular Ad Hoc Network (VANET). Though geographic
routing in VANETs was recently the cynosure, developing multi-hop communication
in such networks is challenging due to changing topology and network
disconnections resulting in failures/inefficiency in traditional MANET routing
protocols. As GPS (Global Position System) use increases, progress on
self-configuring localization mechanisms and VANETs geographic routing provides
message delivery solutions. The need to study VANETs routing protocols is
linked to data exchange expansion in vehicles which aims to provide dedicated
applications for Intelligent Transportation Systems (ITS). This paper proposes
the use of Particle swarm Optimization (PSO) to improve Geographical Routing
Protocol (GRP) efficiency. Simulation results demonstrate that the proposed
modified GRP using PSO, effectively improves the packet delivery ratio, and
reduces the end to end delay.
