Disruption Tolerant Networks (DTNs) are networks that aim to bring low-cost best-effort connectivity to challenged environments with no or limited infrastructures. Nodes in DTNs are often highly mobile and experience intermittent connectivity. Disruption Tolerant Networks (DTNs) use the moving of nodes and opportunistic contacts among nodes for data communication. Owing to the restriction in network resources such as contact prospect, buffer space and bandwidth. By occurring of flood attacks DTNs are liable to danger. The problem of flood attacks is here.
