摘要

本文考虑了

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

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期上下界

因此分簇能极大地提高网络生存期.并且节点服从Poisson分布的分簇网络生存期界与节点服从均匀分布的分簇网络生存期界不同

因此节点的分布方式会显著影响网络的生存期界.

Abstract

Considering time hopping impulse radio ultra wide band (TH-IR UWB) sensor networks composed

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

and that of extended network decrease with the increase of the number of nodes

.The results also indicate the bounds on the lifetime of clustering sensor networks is far more than that of non-clustering network

thus clustering can evidently improve network lifetime.Furthermore

the bounds on the lifetime of clustering TH-IR UWB sensor network which the nodes are distributed according to a Poisson point process are different from that of clustering network which the nodes are placed according to uni

form distribution

thus the behavior of nodes deploying can remarkably affect the lifetime bound.
