无线传感器网络的主要应用之一是为其部署区域提供适当的覆盖。一个无线传感器网络k-覆盖其部署区域，如果在其部署区域中的每个点都在至少k个传感器的覆盖范围内。本文假设传感器在正方形或圆盘区域中部署为Poisson点过程或均匀点过程，研究k-覆盖概率随传感半径或传感器数量的变化。我们的结果考虑了复杂的边界效应，而不是避免它的假设，如文献中所做的环形度规。
One of the main applications of wireless sensor networks is to provide proper coverage of their deployment regions. A wireless sensor network k-covers its deployment region if every point in its deployment region is within the coverage ranges of at least k sensors. In this paper, we assume that the sensors are deployed as either a Poisson point process or a uniform point process in a square or disk region, and study how the probability of the k-coverage changes with the sensing radius or the number of sensors. Our results take the complicated boundary effect into account, rather than avoiding it by assuming the toroidal metric as done in the literature.
