| 摘 要： | 本文考虑了n个传感节点和一个Sink组成的跳时脉冲无线电超宽带(TH-IR UWB)传感网,其中n个传感节点按照Poisson点过程分布在正方形上.推导结果表明密集分簇TH-IR UWB传感网的生存期界随着节点数的增加而增加;而扩展网络的生存期界随着节点数的增加而减小.研究也表明分簇网络的生存期界远大于非分簇网络的生存...

| Abstract: | Considering time hopping impulse radio ultra wide band(TH-IR UWB) sensor networks composed n sensor nodes which are placed according to a Poisson point process on a square and a Sink.The results demonstrate that the bounds on the lifetime of dense network increase with the increase of the number of nodes n,and that of extended network decrease with the increase of the number of nodes n.The results also indicate the bounds on the lifetime of clustering sensor networks is far more than that of non-clustering ... |
