摘要：Mobile ad hoc network (MANET) possess self-configuration, self-control and self-maintenance capabilities. Nodes of MANET are autonomous routers. Hence, they are vulnerable to security attacks. Collaborative attacks such as black hole and wormhole in MANET are difficult to be detected and prevented. Trust based routing decision is an effective approach for security enhancement in MANET. In this study, trust computing using fuzzy based max-product composition scheme is applied to compute aggregated trust values to determine malicious nodes and thereby safe route in MANETs. The results show performance improvement of proposed protocol over AODV protocol. Network metrics are analysed under different mobility conditions and different positions of black hole nodes.
