摘要
Ad Hoc网络覆盖区的重叠率是描述网络拓扑结构的一个重要的指标参量,而网络的拓扑结构对提高网络性能有重要的意义。从几何角度对覆盖区域重叠率与重叠角的关系进行了探讨,在等径圆覆盖的Ad Hoc网络中,覆盖区域的重叠率与重叠角成一对一的函数关系,当拓扑结构为6圆形时,重叠率为5%,当拓扑结构为4圆形时,重叠率为18%。在非等径圆覆盖的Ad Hoc网络中,重叠率由两圆的半径和它们的重叠角同时决定。
The overlap rate in Ad Hoc network- covered field is an important index parameter in describing network topology, and network topology plays an important role in improving network performance. In this paper, the relation between overlap rate and overlap angle in coverage region is discussed from the geometrical view. In Ad Hoc networks covered by equal diameter circles,the overlap rate and overlap angle in coverage region are in a one to one mathematical function relationship. When the topology is constituted of 6 circles, the overlap rate is 5 percent, and when the topology is constituted of 4 circles,the overlap rate is 18 percent. In Ad Hoc networks covered by non- equalization diameter circles, the overlap rate is determined by the radius of both circles and their overlap angle as well.
