| 摘 要： | 无线传感器网络的连通性是确保节点成功组网的基础,相对于内部节点,边界节点对无线传感器网络的连通性有着更大的影响.本文以节点的有效通讯面积为基础,通过理论推导,分析了边界节点的连通性和网络的整体连通性,而后通过仿真研究,分析了存在边界节点与消除边界效应后的网络连通度分布、连通度期望和网络是κ点连通的概率,从而说明了边界节...

| Abstract: | Wireless Sensor Network connectivity is the basis for the nodes to form a network successfully.Compared with inner nodes,border nodes make more effects on the connectivity of a Wireless Sensor Network.Based on the effective communication area of a node,the connectivity of border nodes and network were analyzed through theoretical derivation.Then,through simulation method,the distribution of network connectivity,the expectation of network connectivity and the probability of a k-connected network were discussed in the situation of existing border nodes and eliminating border effects.Finally,the effects of border nodes on the connectivity of Wireless Sensor Networks were summarized. |
