Performance Evaluation of AODV, OLSR and DYMO Protocols for Vehicular Networks Using CAVENET

In VANETs and MANETs, the topology of the network changes very often, therefore implementation of efficient routing protocols is very important problem. In MANETs, the Random Waypoint (RW) model is used as a simulation model for generating node mobility pattern. On the other hand, in VANETs, the mobility patterns of nodes is restricted along the roads, and is affected by the movement of neighbour nodes. In this paper, we present a simulation system for VANET called CAVENET (Cellular Automaton based VEhicular NETwork). In CAVENET, the mobility patterns of nodes are generated by an 1-dimensional cellular automata. We improved CAVENET and implemented some routing protocols. We investigated the performance of the implemented routing protocols by CAVENET. The simulation results have shown that DYMO different from OLSR tries to use more hops to keep the communication between nodes and has not a buffer as in case of AODV. Thus, the route maintenance mechanism of DYMO is better than OLSR and AODV for VANETs.
