WSN中规则区域的最优覆盖研究

Research on Optimal Coverage Problem of Regular Region in WSN

无线传感网是近年来快速发展的新技术,覆盖与连接是无线传感器网络研究中的核心问题,因而引起业界普遍关注并成为研究热点。针对无线传感网络最优覆盖问题,明确了最优覆盖的概念与定义,提出一种运用分形理论自相似性原理进行区域划分以构建最优覆盖模型的方法。通过分析与实验,表明该模型在区域覆盖和面向目标覆盖的无线传感器节点的优化部署上,具有简单快速、容易实现全覆盖而且冗余及网络功耗较小的特点,能有效地降低网络部署成本和能耗。

The technology of WSN has developed rapidly recently. Coverage and connectivity is the core of WSN research. So it is paid the attention by the industry,and become the research focus. For wireless sensor network optimal coverage problem, a method of construc- ting the network optimal covering model is presented in this paper,which uses the fractal theory of self-similarity to divide observation region. At the same time, put forward the optimal covering concept and definition. Through the analysis and simulation results show that the wireless sensor node deployment optimization of the model in the regional coverage and object oriented coverage, has characteristics of the simple and rapid, easy to achieve full coverage and redundancy,and smaller network power, can effectively reduce the network de- ployment cost and energy consumption.
