In this paper, we present an adaptive fault-tolerant event detection scheme for wireless sensor networks. Each sensor node detects an event locally in a distributed manner by using the sensor readings of its neighboring nodes. Confidence levels of sensor nodes are used to dynamically adjust the threshold for decision making, resulting in consistent(More)
This paper presents a distributed adaptive scheme for detecting faults in wireless sensor networks. Each sensor nodes makes a local decision based on the comparisons of its own readings with those of neighbors, along with the dissemination of the decision to them, if necessary. At the end of each fault detection cycle, each node dynamically adjusts critical(More)
