Fuzzy information exposure paths analysis in wireless sensor networks

Based on Fuzzy Theory, this paper proposes an exposure path algorithm for a point and for a path in sensor networks. The fuzzy information exposure path of a point is defined as the function of the distance between sensors and objects. Within a fixed distance, the less the distance is, the higher the exposure. The fuzzy information exposure for a path is the average fuzzy information exposure of all points along the path. The higher the fuzzy information exposure, the higher the confidence level that some information of an object is exposed and the more likely the object is monitored. An approximation algorithm is proposed to solve the problem of finding the worst and best fuzzy information exposure path in wireless sensor networks, and simulations are implemented to evaluate its performance.
