Unicast Routing Protocols in Vehicular Adhoc Networks: A Comparative Analysis

Vehicular Adhoc networks are the networks built by means of the principles of Mobile ad hoc networks (MANETs).This allows effortless and effectual communication between vehicles without the need to create a permanent infrastructure.The applications of VANET are increasing as we are moving towards the era of fully autonomous self-driving vehicles.Various routing protocols have been proposed in vehicular Adhoc networks.In this paper we have done comparative analysis of frequently used unicast routing protocols in vehicular adhoc networks.This comparative analysis is based on qualitative comparison of commonly used unicast routing protocols.This will give us the clear view of the strengths and weaknesses of the available unicast routing protocols of VANETs.Primary focus of the comparative analysis is autonomous self-driving vehicles and based on the results of comparison it is suggested to use WLANWiMAX Double-Technology Routing (WWDTR) for wireless communication in autonomous vehicles.
