A Comparative Study of AODV & DSR with Varying Speed, Pause Time, and Node Density over TCP Connections in VANET

Abstract

This paper presents a comparative study of two routing protocols in vehicular ad hoc networks, popularly known as VANETs. A VANET is a special type of ad hoc network consists of moving cars referred to as nodes; provide a way to exchange any information between cars without depending on fixed infrastructure. Due to rapid topology changing and frequent disconnection makes it difficult to select suitable mobility model and routing protocols. Hence performance evaluation and comparison between routing protocols is required to understand any routing protocol as well as to develop a new routing protocol. In this research paper, the performance of two on-demand routing protocols AODV & DSR has been analyzed by means of packet delivery ratio with varying speed limit, pause time, and node density under the TCP connection.. Finally, it concludes the discussion by pointing out some open issues and possible direction of future research related to VANET routing.
