Transient Fault Tolerant Wireless Sensor Networks

Intermittent and transient faults are the largest source of failure for sensor networks. In order to provide a method for detecting permanent, intermittent and transient faults, a distributed detection algorithm is developed. This algorithm uses repeated testing in discrete time and considers the case of system level faults. It subsumes several algorithms already reported in the literature. Simulation result shows that the false detection rate is well under control while maintaining high detection accuracy.
