摘要：Delay/Disruption Tolerant Networks (DTNs) is one of the important areas in wireless communicationnetwork, where in node sparseness and delays are particularly high in DTN. DTNs are characterized by large end-toendcommunication latency and the lack of end-to-end path from a source to its destination. These characteristicscreates several challenges to the security of DTNs. Malicious and selfish behaviors represent a serious threat againstrouting strategy in Delay/Disruption Tolerant Networks (DTNs).Disruption-Tolerant Networks (DTNs) composed ofintermittently connected nodes. Malicious nodes within a DTN may attempt to delay or destroy data . Such attacksinclude dropping data, flooding the network with extra messages, corrupting routing tables, and counterfeiting networkacknowledgments. In this work the proposed local and global feedback Schema to prevent the selfish and maliciousnodes. Using this schema it is possible to predict the behavior of the node. This Schema could ensure the security ofDTN routing at a reduced cost.
