Performance Evaluation of AODV, OLSR and GRP Routing Protocols in Vehicular Highway Environment

摘要

Vehicular Ad-hoc Network (VANET) turning into a hot research topic because of its pertinence in the areas of road safety, entertainment and driving experience. In wireless networks the information losses are obsessed with the nodes speed, the routing protocol used and therefore the accessible channel. The main objective of this paper is to compare the performance of three routing protocols particularly Ad-hoc On Demand Distance Vector (AODV), Optimized Link State Routing (OLSR) and Geographical Routing Protocol (GRP) from a single node point of view under highway mobility pattern with voice traffic in terms of routing traffic sent and received, end to end delay and throughput. According to simulation results it's clearly discovered that GRP protocol performed better than other protocols in terms of routing traffic sent and received and throughput whereas OLSR is the most effective for time sensitive applications.
