Mobile Ad Hoc Networks, also known as MANET's are the part of many heterogeneous networks which utilizes the technologies like Internet of Things. Internet is filled with known as well as unknown sources which are still considered as a challenge. Secure routing is always a major concern in MANET's. Among all the existing and proposed cryptographic approaches to provide security to these networks seemed lengthy, complex and inefficient in eliminating malicious nodes. Many trust based approaches are proposed to replace these traditional cryptographic security methods for secure routing in MANET's. But all those trust based approaches concentrate on either direct observations or hybrid observations to determine the node's trustworthiness without taking into count network parameters. Considering the security challenges that arise due to the topology, infrastructure and bandwidth of MANET's, a novel secure trust based approach (STBA) is proposed in this article to strengthen the evolution of trust component for effective isolation of malicious nodes and secure routing. This work focuses on the computation of the node's trust factor based on network parameters and node's behavior to simulate the challenge of providing the secure transmission. The proposed method, STBA computes secure trust of a node depending on three tier observations. The performance of the proposed secure trust mechanism STBA is evaluated by comparing it with routing without any trust calculation, with existing Belief based Trust Evaluation Mechanism (BTEM) and Novel extended trust based mechanism (NETM) where routing is performed involving only with direct and indirect trust computation for node's distribution in both cases. Results show the proposed method is performing well. [ABSTRACT FROM AUTHOR] |
