Analysis of GPS and Zone Based Vehicular Routing on Urban City Roads

The speedy movement of vehicles in urban city roads results in numerous changes of vehicles' position and speed. This behavior leads to many wrong packet forward decisions for vehicles in Vehicular Ad Hoc Network (VANETs), which has emerged as a novel class of Mobile Ad Hoc Networks (MANETs). Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communications have been involving an extensive interest in providing Intelligent Transportation Systems (ITS). This paper presents the routing behaviors of GPS-based and zone-based vehicular routings for V2V communication in Urban City Roads. Vehicular routing protocols are simulated in three different simulators (i.e., SUMO (Simulation of Urban Mobility), MOVE ( MObility model generator for VEhicular network) and NS2(Network Simulator 2)) to generate road traffic, urban simulation scenario and examine the performance of protocols, such as throughput, delay and overhead. According to the simulation results, GPSR gives better results than ZRP and is a good choice to optimize for the vehicular ad hoc network.
