| 摘 要： | 定义感知覆盖、通信覆盖和连通覆盖3个基本概念，并给出它们的物理模型和数学模型。提出二维区域上的正六边形节点覆盖模型，证明该模型是重复最少的无漏洞覆盖模型。分析基于正六边形节点覆盖模型的二维区域覆盖，当节点发射半径大于或等于 倍感知半径时，可保证网络的通信覆盖和连通覆盖的最少邻居节点数为6，节点感知覆盖率为82.7%。研究结果表明，正六边形节点覆盖模型更适于二维区域覆盖。

| Abstract: | This paper defines three basic conception including sensorial coverage,communication coverage and connectivity coverage,and gives their physical models and mathematical models.It proposes the regular hexagonal node coverage model applying to 2-D region.It is proved that the model can get coverage to repeat the least without loopholes in 2-D region.The least neighbor nodes to ensure connectivity coverage and communication coverage are 6 for 2-D regional coverage based on the regular hexagonal node coverage model,when launching radius of the node is greater than or equal to 3~（1/2） times of sensorial radius.Node’s sensorial coverage rate is 82.7%.Study result shows that the regular hexagonal node coverage model is more suitable to the 2-D region. |
