TL;DR
A new approach for detecting faults in distributed wireless sensor network based on error function proportional to the deviation between the measurements is proposed and new coefficients to measure the difference between measurements and to do the test on the status of the node are determined in order to improve the fault detection algorithm.
Abstract
Wireless Sensor Networks (WSNs) have become an information collection and monitoring solution for a variety of applications. Faults occurring to sensor nodes are common due to the sensor device itself and the harsh environment where the sensor nodes are deployed. As one of the key technologies involved in WSNs, node fault detection is indispensable in most WSN applications. In this paper, a new approach for detecting faults in distributed wireless sensor network based on error function proportional to the deviation between the measurements is proposed. Besides, new coefficients to measure the difference between measurements and to do the test on the status of the node are determined in order to improve the fault detection algorithm. The result of simulations are convenient.
