摘要：A Delay Tolerant Network (DTN) is anintermittently connected network, where intermediate nodes areresponsible for storing, carrying and forwarding messagesbetween source and destination nodes in the absence of acontinuous end-to-end path. Non-continuous connectivity, finitestorage and bandwidth make the role of relay nodes critical.Existing routing protocols in DTNs assume that these nodesalways show willingness to store, carry and forward messagesfrom other nodes. However, some nodes may exhibit a selfishbehavior due to resource limitations or rogue operation, and denytheir cooperation, thus leading to performance degradation of thenetwork. This paper surveys the schemes proposed in theliterature to stimulate cooperation in DTNs
