Fuzzy Based Robust and Delay Aware Routing in Wireless Mesh Network

The reliability of the network is significant for achieving effective communication in the network. The Quality of Service factors node's energy and queue size play vital role for establishing efficient routing in the network. These factors offer reliability in the network through robust and rapid transmission of data. Hence, in this paper these two factors are mainly considered for choosing the best forwarding neighbors during the transmission. Routing with more than one constraint is a NP-Complete problem and it does not have a polynomial solution. Thus, the efficient route construction based on multiple constraints can be achieved through any optimization technique. Fuzzy Logic is one of the optimization techniques for finding an optimum solution for multi constraint problem. The proposed work enhances the existing AODV protocol as Fuzzy-AODV by implementing Fuzzy Logic technique for choosing the best forwarding neighbors based on node's energy and queue size. The simulation analysis is performed using NS-2.The performance of the network is analyzed by considering themetrics such as packet delivery ratio, packet loss, end-to-end delay, throughput and routing overhead.
