Performance Evaluation of AODV Routing Protocol in VANET with NS2

Abstract

-In intelligent transportation systems, the collaboration between vehicles and the road side units is essential to bring these systems to realization. The emerging Vehicular Ad Hoc Network (VANET) is becoming more and more important as it provides intelligent transportation application, comfort, safety, entertainment for people in vehicles. In order to provide stable routes and to get good performance in VANET, there is a need of proper routing protocols must be designed. In this paper, we are working with the very well-known ad-hoc on-demand distance vector (AODV) routing protocol. The existing Routing protocol AODV-L which is based on the Link expiration time is extended to propose a more reliable AODV-AD which is based on multichannel MAC protocol. For the performance evaluation of routing protocols, a simulation tool 'NS2' has been used. Simulation results show that the proposed AODV-AD protocol can achieves better performances in forms of high Route stability, Packet Delivery ratio and packet loss rate than traditional AODV-L and traditional AODV.

“…However, this protocol was not suitable for VANET environment which has dynamic nature. Reliable AODV protocol which is the Link expiration timebased, is proposed, namely AODV-L [19]. This algorithm is combined with new designed MAC protocol for VANET that uses multiple channels which named AODV-AD.…”

A Node-Protection-Based ZBR Routing Algorithm

“…Yet neither the excessively fast energy consumption of nodes with different network depths, or those that are close to the coordinator cluster heads, are considered. Rathi and Welekar [21] proposed ad hoc on-demand distance vector-adhoc routing(AODV-AD) algorithm based on Link Expiration Time(LET) calculation of equilibrium node energy consumption. Anzola et al [22] proposed a clustering wireless sensor networks(WSN) routing protocol based on k-dimensiona tree algorithm, which can protect nodes by reducing energy consumption of information transmitted by nodes.…”

Energy Based Performance analysis of AODV Routing Protocol under TCP and UDP Environments

“…The topology of such networks cannot be locked and generally modify many times [6]. Due to such nature, ad hoc network has limitations e.g energy utilization, small bandwidth and narrow channel size [7]. Nodes movement changes the routes of the network.…”

“…Ad Hoc on Demand Distance Vector (AODV) is a type of ad hoc networks and considered as a reactive protocol. It is a source driven routing protocol in which communication starts only when desired by source node [2,5,7,8]. AODV is used for unicast [7] and multicast routing [12].…”

“…It is a source driven routing protocol in which communication starts only when desired by source node [2,5,7,8]. AODV is used for unicast [7] and multicast routing [12]. Only those nodes maintain routing information in the routing table which is presented in the [3,4,13].…”
