Implementation of Trust-Based Novel Approach for Security Enhancements in MANETs

MANET is completely a unique, self-sustained wireless communication network. It can be created when necessary without any infrastructural support. Mobile ad hoc networks (MANETs) have many nodes with good network communication capabilities. Being self-organizing in nature, the secured way of transferring the data is an important issue in case of multi-hop wireless networks in real-time systems. Hence, trust confirmation among MANET nodes is the major concern beneath bandwidth limitations, energy and dynamic topology. The malevolent nature prompts the insecure data transfer by reducing the degree of trust among the nodes, leads to a lot of energy consumptions and decreases the network link lifetime. Hence proposed, a unique Novel Energy Efficient Trust Aware Routing (NETAR) for traditional AODV protocol to improve the three degrees of trust among the nodes in MANET using neighbour-node trust rate estimation, bandwidth calculation, energy and malicious behaviour predictions with certain performance measurements to improve the Network Link Life Time (NLT) like Packet Delivery Ratio (PDR), end to end delay, false positive and throughput. The NS2 simulator tool is used. The simulation results show the improved performance of the proposed NETAR protocol compared to the existing protocols.
