Performance and Execution Evaluation of VANETs Routing Protocols in different Scenarios

VANETs an application of MANETs, a fast growing, promising and emerging technology provides basis for ITS following IEEE 802.11p standard based on DSRC designed for WAVE. VANETs enable communication among vehicles (V2V) and road side infrastructure (V2I), disseminating alert messages regarding road conditions and any other critical situation to ensure safety and avoid losses of precious lives and property. Due to high velocity of moving vehicles and dynamic speedy topology change ultimate optimum routing protocols is still a challenging task in VANETs. It is cleared from the proposed results that there is no such protocol that is best for all kind of evaluation criteria. Infact, each routing algorithm conduct differently in sense of performance metrics. In VANETs timely arrival of data is much important to handle the security threats or any emergency efficiently. In this paper we focused and inspected various routing protocols including AODV, DSR and DSDV for the purpose to find out protocols best suited for all scenarios. The comparison and evaluation of various routing protocols is done on the basis of different performance metric criteria like data throughput, PDR, end to end delay or latency and network stability etc.
