摘　　要：针对无线传感器网络节点的概率感知模型,在满足覆盖要求的条件下,给出了传感器节点工作在有向感知模型下的分段数N与全向感知模型下的覆盖重数K之间的关系表达式。之后加入时间积累因素,给出了时间m、分段数N与覆盖重数K的表达式。基于以上研究,可以将概率感知模型下的有向感知覆盖问题转化为求取全向感知下的覆盖重数问题。In allusion to the probability perceptual model in wireless sensor network node,under the premise of satisfying coverage requirements,the relational expression between the number of N segments in directional perceptual model and the covering weight number K in omnidirectional perceptual model is given by means of concrete analysis and probability calculation.Furthermore,in consideration of the time accumulation factor,an expression among the time m,number of N segments and covering weight number K is offered.Based on these researches,the directional perceptual coverage under directional perceptual model can be converted to seeking the coverage multiplicity under omnidirectional perceptual model.
