Evaluation of routing protocols for Vanets in city scenarios

Vehicular Ad hoc Network (VANET) is a new communication paradigm that enables the communication between vehicles on the road network which falls in two categories: 1) Vehicle to Vehicle (V2V) and 2) Vehicle to Infrastructure (V2I). It has opened door to develop several new applications like traffic engineering, traffic management, dissemination of emergency information to avoid hazardous situations and other user applications. Various approaches of data dissemination in vehicular Network are to inform vehicles about dynamic road traffic condition so that a safe and efficient transportation system can be achieved. However, type of VANET Applications and inherent characteristics such as different network density, fast movement of vehicles make data dissemination quite challenging. To evaluate the performance of routing protocols in city traffic scenarios, we developed a realistic city mobility model with use of MOVE. The performance of routing protocols AODV, AOMDV, DSDV and DSR are examined on the basis of network simulations. Results are then analyzed based on the different Performance metrics to find their suitability of these protocols for vehicular area networks.
