Distributed Fault Diagnosis in Wireless Sensor Networks
Tamal Kanti Saha, Sudipta Mahapatra · 2011
A wireless sensor network consists of a number of sensor nodes connected by links. In wireless sensor networks, some sensor nodes may be faulty due to having faulty sensors or intermittently faulty processing logic units. A system level distributed fault diagnosis algorithm is proposed to diagnose a node and the type of fault of the faulty node. The proposed algorithm is simulated assuming 128 sensor nodes interconnected to form an arbitrary network topology using ns-2.
