MANET is a highly challenged network environment due to its special characteristics such as decentralization, dynamic topology and neighbor based routing. Each node in this network relays its neighbors for routing and message forwarding. Cooperation between nodes should be established without any centralized authority. However, neighbor based communication without any trust worthiness creates a major vulnerability in security related aspects of this network. In this type of environment, trust value plays a crucial role in all of the network activities. So that Ad hoc network also defined as trusted network. Continuous evaluation of node's performance and collection of neighbor node's opinion value about the node are used to calculate the trust relationship of this node with other nodes. By introducing a perfect trust model in the network layer, we can establish secure route between source and destination without …
