Mobile Ad Hoc Networks Security Enhancement With Trust Management

Abstract

The mobility and scalability brought by wireless networks made it possible in many applications. In MANET, discovering the stable, secure, and reliable routes is a challenging research problem due to the open nature of wireless communications. In Zhexiong Wei Routing Trust scheme (ZWRT), Bayesian approach and Dempster Shafer theory is used to evaluate more realistic trust value. Mohamed et al proposed Establishing STAble and Reliable Routes (ESTAR) system in heterogeneous multihop wireless networks. The above existing methods failed to solve the complete problem of information loss in MANETs. There are several other reasons due to which the information may loss in MANETS, such as mobility and congestion of mobile nodes. Therefore, the novel Enhanced Trust-based Secure Routing (ETSR) scheme is presented to deliver stable, reliable, and secure data communication in MANETs. The simulation results demonstrate that ETSR routing protocol improve QoS performance as compared to state-of-the-art techniques.
