论文:在无线传感器网络中,传感器节点收集本地数据,通常通过其它节点将数据转发给基站,因而离基站越近的节点,消耗
的能量越多.如果采用通常的方法,即均匀布置传感器节点,则基站附近的节点将很快消耗完能量,基站也就无法收集数据.本
文通过研究无线传感器网络中的能量消耗,得到了一个布置传感器节点的密度函数,按此函数布置传感器节点可以有效地延长
系统的生命期.理论分析和模拟结果表明,本文的布置方案将系统生命期提高到均匀布置方案的3R2t倍,这里t为传感器节点的
通信距离,R为传感器节点的分布区域半径.-Fusion-based Sensor Placement for Target Detection with Guaranteed Accuracy
Abstract:In sensor networks,sensor nodes collect local data and transfer these data to the base station often relayed by other
nodes.Therefore sensor nodes that are nearer to the base station will consume more energy. If deploying sensor nodes in
general way, i.e. deploying nodes uniformly in the network, sensor nodes nearby the base station will use up energy soon and
the base station can t collect data anymore. This paper presents a density function to deploy sensor nodes through investigating
energy consumption in wireless sensor network. Theoretical analysis and simulation result show that deploying by method of
this paper improve system lifetime to times of deploying uniformly, where t is radio distance of sensor node and R is radius of
the region of deploying sensor nodes.
