摘　　要：针对当前没有将复杂网络中的特征量综合应用到无线传感器网络之中的问题,提出了基于复杂网络理论的无线传感器网络连通性分析方法。该方法利用特征量对无线传感器网络进行拓扑性质研究,分析了随机撒点下的网络由一个连通巨片与若干少量的孤立节点和孤立片组成的特点。通过仿真研究了连通率随通信半径变化的规律,以及节点密度与连通性之间的关系。指出了网络连通率会在临界区间内迅速上升直至达到基本全连通,并在给定区域条件下确定了临界区间的具体值。基于平均度对连通性与覆盖率进行了仿真分析,给出了简化无线传感器网络拓扑结构的建议。Aiming at the problem that the feature amount of complex networks are not applied to wireless sensor networks,a method for analyzing the connectivity of wireless sensor networks based on complex network theory was presented in this paper.The topological property of the wireless sensor networks is studied based on the feature amount.When sensors were random deployed,we considered the network was composed by giant con-nected component,a few isolated nodes and isolated sheet.Through simulation,the relationship between the change of the connectivity and the radius of the communication and the relationship between the density of nodes and the connectivity of the nodes were studied.The network connectivity rate rose rapidly until the critical inter-val was reached,and the value of the critical interval was determined by the given region.A simulation about connectivity and coverage based on the average degree was analyzed.
