Coverage Reliability Evaluation of Wireless Sensor Network Considering Common Cause Failures Based on D–S Evidence Theory

In this article, the coverage reliability of wireless sensor network is evaluated from a new perspective. Based on the D-S evidence theory, we define the concept of belief degree of sensing result, establish a belief-degree-coverage model considering common cause failures, and define three indexes to evaluate the reliability of the above coverage model. In order to calculate the belief degree of the sensor's sensing result considering common...
