Relay Assisted Epidemic Routing Scheme for Vehicular Ad hoc Network

Vehicular ad hoc networks are networks in which no simultaneous end-to-end path exists. Typically, message delivery experiences long delays as a result of the disconnected nature of the network. In this form of network, our main goal is to deliver the messages to the destination with minimum delay. We propose relay assisted epidemic routing scheme in which we tend to use relay nodes (stationary nodes) at an intersection with a completely different number of mobile nodes which differs from existing routing protocols on how routing decision are made at road intersection where relay nodes are deployed. Vehicles keep moving and relay nodes are static. The purpose of deploy relay nodes is to increase the contact opportunities, reduce the delays and enhance the delivery rate. With various simulations it has been shown that relay nodes improves the message delivery probability rate and decreases the average delay. [PUBLICATION ABSTRACT]
