Fault Node Detection and Recovery in Wireless Sensor Network (WSN)

Abstract: This paper proposes a fault node recovery algorithm to increase the lifespan of a wireless sensor network when some of the sensor nodes are getting down. The algorithm is based on the grade diffusion algorithm combined with the genetic algorithm. The algorithm can result into detection and replacement of fewer fault node and more reused routing paths.
