Executive Summary

Wireless sensor network is a self-organized network that consists of a large number of low-cost and low-powered sensor devices, called sensor nodes, which can be deployed in harsh environment; sensor nodes are prone to have faults. It is thus desirable to detect and locate faulty sensor nodes to ensure the quality of service of sensor networks. In Distributed Fault Detection (DFD) scheme for wireless sensor networks the status of each sensor node to be either good or faulty is based on the neighboring nodes, but in the DFD algorithm when the sensor fault probability increases the fault detection accuracy decreases and the false alarm rate increases rapidly.
