Description
Summary:Delivering message in Delay Tolerant Networks is challenging due to its sparse nature and intermittent connectivity. Therefore efficient routing is very important for these networks. Here, we focus on the Spray and Wait routing schemes for Delay Tolerant Networks to avoid identical spraying technique and blind forwarding by mobile nodes. To avoid those problems, we first define an adaptive spraying scheme based on the delivery predictability of nodes. We then formulate an equation based on the number of remaining copies of messages to select a specific spraying technique each time. Thus, we propose to employ multiple spraying techniques during the spray phase of our scheme. Simulation results show that our Multischeme Spray and Wait routing performs better in different network scenarios.
