Performance Comparison of Common Routing Protocols in VANETs Using NS3 and SUMO

Vehicular Ad-hoc Networks (VANETs) are

intelligent transportation systems (ITS) that help avoid

congestion and provide safer roads. VANETs provide wireless

communication among vehicles and between vehicles and road

side units. The vehicles act like nodes and every node has high

mobility and fast changing topology. To make a connection

between nodes routing is done with the help of routing protocol.

The performance of communication depends on how better the

routing takes place in the network. This paper aims to evaluate

the performance of commonly used routing protocols (OLSR,

AODV, DSDV, DSR) in a vehicular scenario using network

simulator NS3 and road traffic simulator SUMO. The

performance evaluation parameters are Average Goodput,

MAC/PHY Overhead and End-to-End Delay. The results of

simulation show that the performance of the DSR protocol in

terms of MAC/PHY overhead and Goodput metrics is higher

than the other protocols evaluated in this paper. As for End-toEnd Delay metric, DSDV protocol has the lowest delay for the

packet to be delivered from the source node to the destination

node.
