Abstract: MANET contains a set of mobile nodes which communicate with each other without any underlying infrastructure and dynamic in nature. Since MANET exhibits the dynamic nature and uncentralized management, the vulnerability of security attack is more and many attacks are possible. Node misbehavior is a serious issue for routing protocols in MANET. A node may misbehave by agreeing to forward packets, and then fail to do. It leads to severe performance degradation of the network. Source and destination nodes not within the same radio range have to depend upon intermediate nodes for successful communication. Trust-based routing protocol is proposed to ensure the trustworthiness of intermediate nodes. It computes and verifies the trust for each mobile node and forwards packets on the foundation of trust. Computation of trust is based on the four different trust components such as affinity, trustworthy, energy, and bandwidth. Based on these trust values, the nodes are classified as trusted or untrusted. Untrusted nodes are isolated from the routing path and disqualified for communication. Then the key exchange mechanism is used to establish more secure communication. The data packets from the source are delivered to the destination in a secure manner that increases throughput and decreases delay since the untrusted nodes are removed from the routing path.
