Analysis of topology based routing protocols for VANETs in different environments

Vehicular ad-hoc networks (VANETs) have received great attention lately with promises of increasing automobile safety and convenience. However, VANET's unique properties and characteristics made the design of routing protocols a very challenging task. Nevertheless, a wide spectrum of routing protocols where proposed in the literature. In this work, we opt to analyze the performance of topology-based routing protocols in different city environments. We used MOVE and SUMO to generate a random map. Then, we increased the area of the map to test its effect on the performance of three topology-based protocols: AODV, DSDV and DSR. Thus, we have performed a test of the speed influence on these protocols' performance with a real map topology. The results show that the reactive protocols outperform the proactive ones and especially AODV presents the best performance in the random as well as the real map with different mobility models characteristics (speed and area size).
