Wireless network is a mobile ad-hoc network (MANET) that means nodes are move dynamically in network. In network layer there be lot of attack but introduce only worm hole attack. When more than one malicious node are create tunnel is called wormhole attack. In this paper we introduce trusted AODV routing protocol which trust value calculate using tangent hyperbolic function. The result shows performance improvement as compared to standard AODV protocol.
