Sensor Networks are usually large collection of sensing nodes collecting data from monitoring environment and transmit to base station by multi hop wireless communication. The occurrences of faults in wireless sensor network are very high due to wireless communication and random deployment policy. Energy conservation in sensor network is another challenge to improve applicability of wireless sensor networks. In this paper, we propose sector based fault detection and recovery technique (SBFDR) which is also energy competent. In SBFDR, sensor nodes are arranged into some clusters. Cluster head and sensor nodes are jointly detect the fault of sensor nodes. Sensor node’s faults are recovered by the cluster head’s fault recovery policy. The simulation result depicts that the SBFDR technique more capable to detect sensor nodes faults and recover the faulty nodes in an energy efficient manner. Energy loss and fault recovery time is very low in SBFDR technique compare to other popular fault detection and recovery techniques.
