In this paper, the authors are proposing the fault node recovery algorithm which enhance the lifetime of wireless sensor network. When some of the sensor node are shutdown FNR (Fault Node Recovery) algorithm is combination of grade diffusion and genetic algorithm. This algorithm result in fewer replacement of node and more reused routing path form their simulation active nodes in proposed system are increased by 8.7 times than previous system also data loss rate has been reduced by 98.8% and the most important thin i.e. energy consumption rate has been reduced.
