Abstract

A Vehicular Ad hoc Network (VANET) is a wireless ad hoc network that is formed between vehicles on an on demand basis. A lot of research work around the world is being conducted to design the routing protocols for VANETs. In this paper, we examine the significance Greedy Forwarding with Border Node based approach for VANETs to optimize path length between vehicles in different traffic scenarios. This protocol is called Border Node Greedy Forwarding (BNGF) since it uses border nodes with Greedy Forwarding. We categorize BNGF as BNGF-H for highway and BNGF-C for city traffic scenarios. We have simulated this protocol using NS-2 simulator and calculated the performance in terms of end-to-end delay and packet delivery ratio. We compare both the methods for highway and city traffic scenarios. The result clearly show that the end-to-end delay for BNGF-C is significantly lower and packet delivery ratio is higher than BNGF-H.
