unication, are widely used at present. Many sensors interconnected in a region form a work to measure some physical parameters, process data and transmit signals. The wireless sensot works can not only deal with the required inform ation, but also transfer data securely to acplish the inform ation acquisition. It can be used widely in the fields of our living, scientific research, military, Ehospital, intelligent traffic, unmanned scout, intelligent weapo n, and SO on. 無線傳感器網(wǎng)絡目前已得到廣泛應用,它主要有三個信息技術構成,分別是傳感器技術、計算技術和無線通信技術。無線傳感器不僅處理需要的信息,而且安全地傳送數(shù)據(jù)以完成信息獲取。 本文結構:第一部分介紹有關工作。第三部分描述了此模型的仿真分析。 LOGO 2. 以往工作 目前,無線傳感器網(wǎng)絡節(jié)點均勻分布的研究比較少。準確覆蓋理論適合那些節(jié)點位置能準確獲取的情況。 隨機節(jié)點覆蓋是在傳感器節(jié)點隨機展開且不能事先確定的情況。文獻 5通過二分法解決了覆蓋控制問題。在文獻 6中,研究了當節(jié)點移動后如何能保證節(jié)點的覆蓋問題。 At present, the research on distribution uniformity on odes for wireless sensor works can be hardly found. Most scholars emphasized the coverage theory of wirelesssensor works. The typical distribution can be divided as certain coverage and random coverage. Th e certain coverage theory fi
