A multifunctional incentive scheme adaptive to diverse performance objectives for dtn routing

Vimala G and Anjugam P

In Delay Tolerant Networks (DTNs), we can exchange packets only when they meet with each other. The routing is usually conducted in a store-carry-forward manner to exploit the scarce communication opportunities. The nodes may be selfish and may not be cooperative on packet forwarding or storage. The current scenario fails encourage nodes to follow a certain packet routing strategy to realize a routing performance objective. Here, we first discuss the routing strategy that can realize different performance objectives when nodes are fully cooperative, i.e., are willing to follow both aspects of cooperation. We then propose Multi cent, a game theoretical incentive scheme that can encourage nodes to follow the two aspects of cooperation even when they are selfish.
