Fuzzy-based Trusted Ant Routing (FTAR) protocol in mobile ad hoc networks

Abstract

This paper proposes a novel approach called Fuzzy-based Trusted Ant Routing (FTAR) using fuzzy logic and swarm intelligence to select optimal path by considering optimization of multiple objectives. It retains the advantages of swarm intelligence algorithm and ensures trusted routing protocol by implementing fuzzy logic. It uses trust-evaluation scheme using dropped packet and Time-Ratio parameters which calculate trust values for nodes in MANETs to distinguish between healthy and malicious nodes. FTAR considers not only shortest path but also the trusted level of neighbors or intermediate nodes. © 2011 Springer-Verlag.
