Spray and Wait Routing Based on Average Delivery Probability in Delay Tolerant Network

To avoid random and blindfold forwarding decision in Spray and Wait routing in delay tolerant network, Binary Spray and Wait routing based on average delivery probability is proposed in this paper. Based on delivery predictability of PROPHET, average delivery predictability is proposed and used in Binary Spray and Wait routing to make forwarding decision. Furthermore, we evaluate it through simulations versus Spray and Wait routing protocol. The experimental results show there has slight higher average delivery rates and shorter average delays in Binary Spray and Wait routing based on average delivery probability.
