Fuzzy Logic-based Trusted and Power-aware Routing Protocol in Mobile Ad-hoc Networks

Abstract

Mobile ad-hoc networks (MANETs) have attracted much attention from researchers lately because MANETs are able to provide networks in areas with unavailable fixed network infrastructure. However, some mobile nodes may misbehave by dropping packets to conserve power usage because mobile ad-hoc networks nodes are usually battery operated. In this paper, a fuzzy logic-based routing protocol that considers the battery level of nodes, hop count, and trust among the nodes is proposed. The proposed routing protocol adaptively selects routes that use minimum hop count with the highest level of trust and a sufficient battery level to enhance the reliability of route selection while maintaining the percentage of successfully delivered packets. The result of the simulation shows that the proposed protocol can achieve a high ratio of successfully delivered packets, a lower average end-to-end delay, and a normalized routing load.
