Concurrent Diagnosis of Clustered Sensor Networks

چکیده
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 clusterheads. 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.

FDMG: Fault detection method by using genetic algorithm in clustered wireless sensor networks
Wireless sensor networks (WSNs) consist of a large number of sensor nodes which are capable of sensing different environmental phenomena and sending the collected data to the base station or Sink. Since sensor nodes are made of cheap components and are deployed in remote and uncontrolled environments, they are prone to failure; thus, maintaining a network with its proper functions even when und...
