In Power efficient routing for MANET is very crucial due to its dynamic topology, complexity and limited resources. The battery efficiency and power consumption of the selected routes play a vital role in the network lifetime. An optimum balance between these two constraints has to be made during route selection in order to obtain stable routes that would avoid network partitioning. In this paper, we propose an adaptive routing FBPRA (Fuzzy based Balanced Power Aware Routing Algorithm) that incorporates a path maintenance mechanism and selects the most stable route using fuzzy logic. The path maintenance mechanism reduces the path breakages by establishing a new path via the neighbouring nodes, before the packet transmitted path could break due to the node's mobility. The performance evaluation is done using a simulation program to compare between our fuzzy logic approach and the classical methods. The simulation results show that the algorithm improves the network performance effectively.
