摘要: 传感器放置是传感器网络研究的核心问题之一。本文在Dhillon S.S.的模型化传感器节点、障碍物和优先覆盖方法基础上,提出了一种新的高效覆盖传感器放置模型及整体局部覆盖算法。该模型着重考虑传感器探测范围的局限性,给出传感器探测角度和探测距离模型,修改了现有算法的初始化过程。理论分析和仿真试验充分验证了该模型的可行性和优良的覆盖性能。

Abstract: Senso r placement i s o ne of the key topics addressed in sensor netw o rks study. This pa per pro poses a nov el sensor placement model and a so-called IN T EGER LOCAL COV algo ri thm wi th a mo re ef ficient cov erag e, based o n the modeling of the node characteri stics, terrain shield and preferentia l cov erag e of g rids as tha t analy zed by Dhi llo n S. S. . In the new placement scheme, the detection limi t of senso rs i s al so carefully modeled, such as the perception rang e and ang le of view , and th e ini tiatio n process is rev ised acco rding ly. Theoretical analy ses a nd the simulatio n demo nst ra te the ef fectiv eness and the out standing performance of the presented model compared w ith the original placement algo ri thms.
