Resilient Event Detection in Wireless Sensor Networks

Angelika Herbold, Thierry Lamarre, Nirupama Bulusu and Sanjay Jha

Abstract

As wireless sensor networks become widely used, the need to provide fault tolerant, user-friendly middleware for detecting sensed events increases. Our contribution is the motivation, design, implementation and evaluation of ResTAG, which provides fault-tolerant aggregate queries in the popular, user-friendly TinyDB middleware. If a sensor becomes mis-calibrated or physically compromised, the fault-tolerant queries use the network redundancy to reduce the confidence in any report from that sensor. Queries implemented using ResTAG detect faulty nodes within a predictable threshold that depends on both the percentage and failure type of faulty nodes.
