Efficiency evaluation of routing protocols for Vehicular Ad-Hoc Networks using city scenario

By means of recent advancements in the wireless networking area a totally new paradigm came into existence in the domain of wireless communication well known as Vehicular Ad-Hoc Network (VANET) employed specially for providing road safety, comfort and convenience to the driver as well as passengers during their journey. A VANET is a type of highly dynamic wireless network that can be formed without the need for any pre-existing infrastructure which aims to improve the transportation system by integrating sensors, wireless networks, GPS, 2G and 3G technologies with the ad-hoc networks. Due to higher mobility of nodes (vehicles), routing becomes the most challenging task in VANETs. A variety of research has been done on routing and several protocols have been proposed with their implementation. In this paper, we evaluate the efficiency of two routing protocols one is proactive (Table-driven) OLSR protocol and another reactive (On-demand) AOMDV by comparing their performances in the city scenario for the map of city of Arlington, Texas using NS-2. The realistic vehicular mobility traces are generated using Intelligent Driver Model (IDM) based tool VanetMobiSim.
