在无线传感器网络监视预警应用中，“边界”的地位突出而重要。为了提高边界区域内的监测概率，研究了节点为概率感知模型条件下的分布式多重覆盖算法。根据传感器节点感知圆盘的相互关系，将整个边界区域划分为不可再分割的可数个最小区域块，然后利用改进的贪婪式算法对整个边界区域进行分布式多重覆盖算法研究，最终通过仿真比较，验证了非理想状况下对边界区域实行多重覆盖可在保证能效的前提下有效提高边界覆盖率。

Boundary occupies an important and outstanding place in wireless sensor network monitoring and warning application. In order to improve the detection probability,distributed multiple coverage algorithm is discussed under the condition of probability perceptual node model. The entire boundary region can be divided into countable smallest regional block based on the relationship between the node sensing disc. Then this article carries out a distributed multiple coverage study to this boundary region by using an improved greedy algorithm. At last,in non ideal conditions,by means of simulation results,the article verifies that multiple coverage of the boundary region can improve the coverage probability in the premise of energy efficiency.
