摘要
综合考虑无线传感器网络中的连通与覆盖问题,提出了一种新的同构无线传感器网络网格划分方法,即正六边形网格划分方法。通过数学推导和理论证明,该正六边形网格划分方法充分利用了每个节点的圆域面积,比传统的正方形网格划分方法使用更少的节点。最后,比较了该正六边形网格划分方法与正方形网格划分方法的功耗情况,计算结果显示,前者性能更优。
In wireless sensor networks, it is crucial to consider connectivity and coverage issues together. The paper focuses on these two problems, proposed a new method of regular hexagonal grid plot for wireless sensor network. By means of theoretical proving and computing, the result shows that this method of grid plot not only demand less sensor nodes, but also have a very outstanding low energy-consuming characteristic. Although so many advantages, this method of grid plot is only a ideal model, a lot of work have be done to make it adopt to specific applications.
