ROUTING PROTOCOLS IN VANET SYSTEM: A REVIEW
Journal Title: International Journal of Electrical, Electronics and Mechanical Fundamentals (www.ijeemf.com) - Year 2012, Vol 1, Issue 1
Abstract
Vehicular Ad-hoc Network (VANET) is a collection of communication vehicles, moving in different directions. The vehicles form a communication group to disseminate desired information. Various routing protocols are implemented in a VANET, each having benefits and shortcoming in the domain of implementation. In this paper performance of three routing protocols, namely Ad hoc On-Demand Distance Vector Routing (AODV), Destination Sequenced Distance Vector (DSDV) and Dynamic Source Routing (DSR) is compared for different parameters. The protocols are simulated on Network Simulator-2(ns- 2). From these two extreme approaches we derive a stack-based VANET protocol architecture that combines the strengths of both sides. Among the key features of this protocol architecture are VANET-specific protocol layers, a staircase approach for interaction among layers and the use of an information connector for cross-layer information exchange using the publisher/subscriber pattern? We believe that this protocol architecture provides a clear modular structure with flexibility for protocol interaction and information exchange at a reasonable complexity.
