TRUST ENHANCED DYNAMIC ROUTING FOR MANET

Nowadays Mobile Adhoc Network (MANET) is becoming more popular due to its mobile and ease of deployment nature. However due to wireless and dynamic nature of network topology, it make them more exposed to various types of attacks. The main issue is to assure secure network services. In order to overcome this issue, a Trust Enhanced Dynamic Routing for MANET with Threshold Signature and Randomization process is proposed. In this technique, a secure cluster is formed based on the trust probability value where each node monitors trust value to determine the node trust level and minimum trust level of neighbor node. The node with high trust value is considered as the Cluster Head. In order to overcome the eavesdropping attacks during routing process randomization process is employed which monitors the each node to block malicious and increases node security level. The simulation results determines the comparative study results with the combination of attacks and without attacks.
