چکیده
Vehicular Ad-Hoc Networks (VANETs) have recently gained considerable attention from both research and industry communities. One of the challenges posed by the study of VANETs is the definition of routing protocols design. In this paper, a realistic simulation environment is developed based on Mobility model generator for Vehicular networks (MOVE) and Network Simulator (NS2). The performance of three classical routing protocols such as Ad hoc On-Demand Distance Vector (AODV), Ad hoc On-Demand Multipath Distance Vector (AOMDV) and Dynamic Source Routing (DSR) in various network conditions is evaluated and compared in the developed environment. Network delay, network packet delivery and network routing overhead are simulated with different nodes’ density (vehicles’ number) and under various simultaneous connections’ number. The simulation results show that DSR is not suitable for dense VANETs, while AODV have better network adaptability in dense VANETs. The performance of AOMDV is poor compared to AODV and DSR. Keywords— VANETs; MOVE; NS2; AODV; AOMDV; DSR
