Comparative Study of AODV, DSR and DSDV in Vehicular Ad-Hoc Networks

Vehicular Ad-hoc network consists of wireless mobile nodes which form a temporary network having no centralized infrastructure. VANETs have dynamic topology because of higher node mobility. VANETs provide benefits like road safety, security etc of vehicles etc Therefore, reliable and efficient routing is one of the main challenges in VANETs. Many improved routing algorithms have been implemented for consummate this task and to achieve better results. Therefore, it is very tuff to figure out which protocol executes better results under different kinds of scenarios. At present, a lot of research work like security, entertainment, harmless driving etc in VANETs has been placed as popular issues in the network areas. VANET provides number of protocols for routing which all have unique nature, this unique nature of protocols differ them from the others. One can choose a specific protocol on the basis of features easily for their simulation work. Hence, this review paper presents some protocols and also comparison is evaluated by studying typical representatives of routing protocols structure for VANETs. Keywords— VANET, Routing protocols, AODV, DSR, DSDV.
