Adaptability of MANET Routing Protocols for VANETS

Abstract: In recent years, co-friendly transportation is becoming more and more important. Vehicular ad hoc networks are emerging as a new class of wireless network spontaneously formed between moving vehicles equipped with wireless interfaces, employing short-range to medium-range communication. One of the most distinguishing features of vehicular ad hoc networks (VANETS) is the increased mobility of the nodes. Many routing protocols for MANETS have been proposed to date. Among them, DSDV is a representative table-driven protocol, while AODV and DSR are two representative on-demand protocols. This paper proposes ns-2 simulation result by comparing these three protocols at different number of nodes and at different mobility. This comparison result helps in checking the adaptability of MANET routing protocol for Vehicular Ad hoc networks. The scenarios used in the simulation experiments take into account a variety of environmental factors that influence protocol performance. The performance of the protocols is compared in terms of their packet delivery ratio, end to end delay and routing overhead.
