Fuzzy-Controlled Adaptive and Intelligent Route (FAIR) Selection in Ad Hoc Networks
Ad-hoc networks are collections of mobile nodes communicating with each other using wireless media without any fixed infrastructure. Design of routing protocols for this kind of networks is very difficult due to dynamic characteristics of nodes. In this paper, the authors identify stability and agility of a multi-hop wireless path as the parameters of effective and efficient communication. Stability of a path signifies its sustainability, whereas agility denotes speed of transmission. In order to optimize the twin objectives mentioned above, fuzzy controllers have been embedded in each node. If a node reaches its destination through multiple paths, intelligent destination assigns credit points to them in an adaptive manner. A route with pinnacle credit point is picked up as the optimal choice.
