A wide range of applications have started to use Wireless Sensor Networks (WSNs) as an information collection and monitoring tool. However, the networks may suffer from various factors that degrade their functionality. One of these factors is the frequent deviation of WSN nodes from their normal operation because of sensor device problems, battery issues and harsh environment they are in. These deviations may case a decrease in the quality and the quantity of the collected data, and use more network resources that reduce network lifetime. The goal of this paper is to propose a new distributed performance algorithm that insures the detection of deviations that degrade WSN collected data and reduce their impact on network functionality. Simulation results showed that the proposed algorithm achieved a high-level of detection reliability on node status. In addition, they showed that the proposed algorithm is resilient to both high packet loss and environmental changes.
