Wireless Mesh Networks (WMNs) are the evolutionary self-organizing multi-hop wireless networks to pro mise last mile access.Due to the emergence of stochastically varying network environments, routing in WMNs is critically affected.In this paper, we first propose a fu zzy logic based hybrid performance metric co mp rising of link and node parameters.Th is Integrated Link Cost (ILC) is computed for each link based upon throughput, delay, jitter of the lin k and residual energy of the node and is used to compute shortest path between a given sourceterminal node pair.Further to address the optimal routing path selection, two soft computing based approaches are proposed and analyzed along with a conventional approach.Extensive simu lations are performed for various architectures of WMNs with varying network conditions.It was observed that the proposed approaches are far superior in dealing with dynamic nature of WMNs as compared to Adhoc Ondemand Distance Vector (AODV) algorithm.
