A Review On Fuzzy Logic Based Routing In Ad Hoc Networks

Abstract

Ad hoc networks are increasing in popularity due to the spread of mobile devices. These networks are widely used in emergency situations like natural disasters and military conflicts. The dynamic and infra structureless nature of ad hoc networks makes them suitable for such applications. Self organization and self administration are the key features of any ad hoc network. Due to the dynamic and rapid movement of nodes, routing becomes very difficult in the ad hoc networks. Various routing schemes based on different approaches like Swarm based routing, Fuzzy logic based routing, Trust based routing, Energy level based routing, Secure routing etc. are proposed by the researchers. In the comparison of all the existing approaches, Fuzzy Logic Theory is proved to be a good approach for routing in the ad hoc networks. The main reason behind this is the capability of Fuzzy theory to handle uncertainties and randomness. This paper aims at reviewing the existing fuzzy logic theory based routing protocols that consider QoS parameters as routing metrics.
