Abstract

In this paper we study the problem of fault diagnosis for sensor networks. We examine faults that involve an anomalous behavior of the sensor and investigate their diagnosis only through the local interaction between faulty nodes and healthy ones. We provide heuristics to actively diagnose faults and recover the nominal behavior.
