Position Based Routing protocols in VANET for Better Link Quality: A Survey
نویسنده
چکیده
Vehicular Ad-Hoc Networks, are a specified class of Mobile Ad-Hoc Network, in which vehicles are nodes VANET provides interaction between vehicles and road sides units. VANET now-a-days is affecting a large area of research due to its wide range of applications and special characteristics like movements constraints, On board sensors, Unlimited battery power, high node mobility etc . The main issue in VANET is routing. Routing of information is demanding task as considering rapid changing topology and node mobility of vehicles. In these networks, the link duration is often very short due to frequent changing topology which decreases the network efficiency leading to problem of link stability. In terms of high scalability and low overhead the most suitable solution for routing in VANET is Greedy routing approach. However various location based routing protocols have been proposed by researchers such as the GPSR, the GOAFR, A-STAR, GPCR etc. The main objective of this paper is to compare different routing protocols. The result of comparison identifies one of the efficient routing approaches in VANET.
