Abstract & Overview
With the advancement in the transportation system the need for faster data dissemination is the prime requirement of the network. VANET is a widely used network worldwide because of its specific characteristics. The high mobility and dynamic environment can be easily coped with using Ad-hoc On-demand Distance Vector (AODV) and Greedy Perimeter Stateless Routing (GPSR) routing protocols, which have been widely employed in various vehicular environments. Different metrics such as node density, node speed, bit rate, communication range and traffic pattern are not investigated properly. In this paper, we focus on multimeric approach to evaluate the performance of AODV and GPSR in five different scenarios in an urban environment using NS2 simulator. The in-depth impact of the metrics on the performance of routing protocols are investigated and the QoS parameters is measured which will help in the fast data dissemination, low latency and high throughput requirement fulfilment for the given vehicular environment.
