Wireless Sensor Network (WSN) is type of network which consists of collection of tiny device called sensors nodes. In real wireless sensor networks, the sensor nodes use battery power supplies and thus have limited energy resources. This paper decrease the number of fault node and loss data and number of routing in the network based on enhanced Grade Diffusion with using Shortest Best Path .In the simulation, number of hop, power consumption, fault detection accuracy and time number of neighbour nodes measure the proposed algorithm. The proposed algorithm is also compared with distributed fault detection (DFD) and fault node recovery (FNR).
