Cluster-Based Error Messages Detecting and Processing for Wireless Sensor Networks

Wireless sensor networks (WSNs) have emerged as a new technology about acquiring and processing messages for a variety of applications. Faults occurring to sensor nodes are common due to lack of power or environmental interference. In order to guarantee the network reliability of service, it is necessary for the WSN to be able to detect and processes the faults and take appropriate actions. In this paper, we propose a novel approach to distinguish and filter the error messages for cluter-based WSNs. The simulation results show that the proposed method not only can avoid frequent re-clustering but also can save the energy of sensor nodes, thus prolong the lifetime of sensor network.
