Minimax Theory Based Scheme to Detect Selfish Node and Reduce Latency in Delay Tolerant Network

Delay Tolerant Networks are resource constraint network. Selfish behavior of a node causes it to drop legitimate packets of other nodes, leading to low message delivery and wastage of valuable network resources. Here a Minimax Theory Based Scheme is proposed to distribute credits among non selfish nodes .It reduces the message dropping rate, detects selfish node and enhance network performance in terms of latency, aborted message rate and delivery ratio.
