| 摘 要： | 在自组织传感器网络中,覆盖和连通是评价传感器网络性能的两个重要指标,而且这两个指标本身有着内在的关系,在一个不可靠的传感器网络中,这两者和传感器的失效概率密切相关.提出了一种传感器网络模型,并在此基础上提出了一种新颖的对ROI的正三角形区域划分方法.根据这种划分,得出了传感器的覆盖和连通概率与节点感知半径、发射半径、失效概率及节点数量之间的关系,对传感器网络的构建具有指导意义.

| Abstract: | This paper considers the problem of coverage with connectivity in large-scale unreliable sensor networks. Based on an abstract sensor network model, a novel triangle-arranged circle division method is proposed to model a sufficient condition for the network to maintain coverage with connectivity . Then using probability method, we derive the formula between the probability of coverage with connectivity and parameters of network. Since our method has no restriction on the relationship between transmission radius and sensing radius, the resultant establishment can be applied to more broad applications. |
