An efficient coordinator selection method for Geo-routing protocol in vehicular network

Abstract

With the advancement in transportation system, vehicle to vehicle and vehicle to infrastructure communication has drawn much attention. For delay intolerant networks like VANET, efficient routing mechanism is one of the major concerns. Geo-routing protocols provide the best services in this regard because of their simplicity and for not having route discovery process. Though coordinator vehicles are preferable for forwarding a packet in most of the existing geo-routing protocols, there is a lack of research on coordinator selection method. A coordinator is a vehicle which has the maximum number of neighbours around it and thus helps to forward the packet more efficiently. The main objective of this research is to introduce an efficient and durable score-based coordinator selection method for the geo-routing protocol of VANET. The results show that the selected coordinator is stable over a considerable period of time. As a result, less number of control packets are exchanged between the nodes and network faces lesser delay.
