Delay/Disruption Tolerant Networks (DTNs) is one of the important areas in wireless communication network, where in node sparseness and delays are particularly high in DTN. DTNs are characterized by large end-to-end communication latency and the lack of end-to-end path from a source to its destination. These characteristics create several challenges to the security of DTNs. Malicious and selfish behaviors represent a serious threat against routing strategy in delay/Disruption Tolerant Networks (DTNs). Disruption-Tolerant Networks (DTNs) composed of intermittently connected nodes. Malicious nodes within a DTN may attempt to delay or destroy data.
