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.
