Data forwarding method with black hole attack detection function

The invention relates to a data forwarding method with a black hole attack detection function and belongs to the technical field of opportunistic network trust management. In order to solve the problems that existing black hole attack detection methods in an opportunistic network only detect attack behaviors of black hole nodes in a certain aspect and lack relatively comprehensive evaluation on the black hole nodes and detection results are affected by certain changes of the network easily, during black hole attack detection, trust conditions of the nodes in all aspects are required to be considered comprehensively, comprehensive judgments are made, and an opportunistic network trust management method for comprehensively judging node credibility according to node experience in the aspects of the accuracy degree of routing information provided by to-be-detected nodes, the reliability of historic behaviors of the nodes, the forwarding capacity of the nodes for messages and the like is further designed. With the adoption of the method, the reliability of the nodes is accurately judged, and detection results cannot be affected by other factors in the network easily, so that the delivery rate of the messages in the network is increased, and the performance of the network is enhanced.
