摘要：Wireless networks are infrastructure less, where every node utilizes the opportunistic contact for data communication. Due to the dynamic nature, several security threats arise in such networks. The lack of infrastructure less and dynamic topology makes it impossible to establish a proper connections in ad - hoc networks. In such network store - carry - forward s trategy can be employed. But, those routing process depends heavily on the cooperation among other nodes. In the infrastructure free network, the selfish behavior of nodes affects the overall performance of the packet transmission. Selfish or malicious behaviors of nodes impact greatly on the network performance. In this paper, we analyze and design a n active trust handling model for secure routing optimization against selfish and energy. In this paper, we focus on both selfish and malicious nodes in opportunistic contact networks. Here the malicious nodes are considered as the energy suckers, where selfish behaviors could be identified easily using existing EBOX. So our proposal improves the reliability among dynamic topological env ironment against selfish and energy suckers. The above stated problem in opportunistic network is handled by incorporating two mechanism named as evidence collection and acknowledgment verification. This is handled by the heuristic method, where the optima l and prioritized attribute or behavior is considered initially. This reduces the time for the attack detection
