Reliable Routing in VANET Using Cross Layer Approach
Mr. Bhagirath Patel,  Ms. Khushbu Shah
Vehicular Ad hoc Networks (VANETs), a subclass of mobile ad hoc network (MANET), is a promising approach for the intelligent transport system (ITS). Routing in VANET is more complicated then MANET due to unique characteristics like high dynamic nature, predictable mobility, scalability and frequent disconnection. In recent years, A stateless routing turn attention of researchers as it provides promising simulation result. Each stateless routing is based on the multihop forwarding approach, and for that routing protocols like MOPR, R-AOMDV, GPSR-MA uses the cross layer parameter to select the next forwarding hop. Here a novel approach is proposed for selecting a next forwarding hop based on the parameter get from the MAC-PHY layer. In this approach speed and position parameter are carried out from the lower layer (MAC) and used in Routing layer (Network) for promising forwarding hop selection. Here a threshold value is applied over a communication range of node for limiting a packet drops due to unreliable signal strength and within this range a node with highest speed toward destination is selected, as higher speed node can travel more distance towards destination, and this resulting into a lower end to end delay.
