Abstract: This paper studies the fuzzy information exposure paths in Wireless Sensor Network(WSN), and presents an algorithm to dispose the fuzzy information in both of optimal and worst way. It builds the fuzzy coverage model based on the sensor coverage radius, the fusion parameters and coverage threshold. The influence from the fusion factor and parameter of coverage intensity on path information exposure is analyzed. Simulation results show that compared with the probability coverage model, the fuzzy coverage model can get less information exposure intensity on the worse path, while more intensity on the optimal path.

摘要： 研究无线传感器网络中的模糊信息暴露路径，提出模糊信息暴露最佳(最差)路径算法，根据传感器覆盖半径、融合参数以及覆盖阈值，建立模糊覆盖模型。分析覆盖强度融合因子与融合参数对路径信息暴露强度的影响。仿真结果表明，与概率覆盖模型相比，模糊覆盖模型的最差路径信息暴露强度更小、最佳路径信息暴露强度更大。
