Minesweeper for Sensor Networks--Making Event Detection in Sensor Networks Dependable
Karima B. Hein, Reinhold Weiß · 2009
Event detection using wireless sensor networks (WSNs) has become a new field of research in the past years, increasing the need for dependability and fault tolerance. Our work exploits the massive redundancy of large WSNs in combination with neighbours' relations to identify faulty nodes. We present a new approach to categorize nodes in being faulty or fault free based on the event detection results of the nodes' neighbours and the nodes adjacent to the neighbours. For error probabilities < 0.2 our algorithm performs closely to other work in the field, and performs considerably better for error probabilities up to 0.5.
