OVERVIEW OF ROUTING PROTOCOLS FOR VEHICULAR AD-HOC NETWORKS?

Vehicular Ad hoc Networks (VANETs) is the new wireless networking concept of the wireless ad hoc networks in the research community. Vehicle-to-Vehicle (V2V) communication plays a significant role in providing a high level of safety and convenience to drivers and passengers. Position based routing protocol has been identified to be suitable for VANETs because of frequently changed network topology and highly dynamic nature of vehicular nodes. Many position based routing protocols have been developed for routing messages in greedy forwarding way in VANETs. However, few of them are efficient when the network is highly dynamic. In this paper, we present an overview of existing routing protocols that are based on the position prediction of neighboring and destination nodes.
