Performance Evaluation of Position-based and Non-position-based Routing Protocols in a Vehicular Ad-Hoc Network

In this paper, we evaluate and compare performance between position-based and non-position-based routing protocols in a vehicular ad-hoc network. The protocols evaluated in this paper for many performance evaluation aspects are a position-based routing protocol, GPSR (Greedy Perimeter Stateless Routing), and the non-position-based such as AODV (Ad-hoc On-Demand Distance Vector) and DSR (Dynamic Source Routing) protocols. The three protocol characteristics such as Packet Delivery Ratio, Latency of first packet per connection, and Average number of hops depending on distance are compared and evaluated. As the result of simulation, the AODV performed better than the DSR. However, due to the high mobility characteristic of a vehicular ad-hoc network, GPSR, the position-based routing performs better than the non-position-based routing protocols such as AODV and DSR in a vehicular ad-hoc network environment.
