Routing messages over vehicular ad hoc networks (VANETs) is usually achieved through geographic routing protocols. In such networks, the vehicle dynamics causes rapid changes on the vehicle density and the communication links. In order to be efficient to route messages from a vehicle to another, we need to locate each node (its position), this is achieved by a location service. This study works on simple location service adapted for unicast routing over VANETs in city environment. This service is able to find a route from a route from a source to the destination and this route is the one passing through the most dense path‥ We have implemented our proposal on the OMNET++ simulator and we have conducted extensive simulations in different scenarios to evaluate its scalability and robustness against frequent topology changes. The results obtained have shown that our proposed protocol provides significant improvements in terms of packet delivery ratio, end-to-end delay and overhead compared to EGyTAR protocol.
