Performance Analysis of Routing Protocols in Realistic Environment for Vehicular Ad Hoc Networks

Abstract

Vehicular Ad hoc Network (VANET) is a new way of communication which includes communication between vehicles moving at high speeds on the roads. VANET developed several new applications like traffic engineering, traffic management, provides emergency information to avoid accidents and other user applications. VANETs are similar to Mobile Ad hoc Networks (MANETs) but with different characteristics like, movement at high speeds, mobility, sufficient storage and processing power, unpredictable node density and difficult communication environment with short link lifetime etc. So for testing of any protocol for VANET needs realistic enviorment. In this paper, we create realistic environment for the performance analysis of proactive and reactive routing protocol in city scenarios is presented. The protocols evaluated are Ad hoc On demand Distance Vector (AODV), Ad-hoc On-demand Multipath Distance Vector Routing (AOMDV) and Destination Sequence Distance Vector (DSDV). In simulations, maps are used to model topology using traffic simulator and then vehicles with different parameter like length, maximum speed and acceleration etc. run on these topologies. The performance evaluation matrices used in this paper are packet delivery ratio and End to End Delay.
