Abstract

In this paper, we present an energy-efficient on-line diagnosis algorithm for cluster-based wireless sensor networks. It employs local comparisons of sensed data and dissemination of the decision made by the comparison results. Cluster-heads act as checkers for their associated cluster members. Redundant sensor nodes, as far as sensing coverage is concerned, are partially utilized to tolerate misbehavior of cluster-heads. Final decision on the fault status of sensor nodes is made at the base station. Computer simulation shows that high fault coverage can be achieved for a wide range of fault rates.
