无线可充电传感器网络中的充电桩部署

Charger Deployment in Wireless Rechargeable Sensor Networks

在传统的无线传感器网络中,由于自身能量存储的限制,电池供电的传感器节点缩短了整个网络的使用寿命,严重影响了网络性能。针对充电桩部署位置固定、位置不固定且不受限以及位置不固定且受限的3种情况,利用整数规划分别给出了具体的部署算法,使得整个传感器网络区域的充电效用最大化。最后利用Matlab进行仿真分析,与传统的全覆盖部署相比,使用该算法可以显著地减少所需要的充电桩数量。

In traditional wireless sensor networks,battery-powered sensor nodes shorten the life of the entire network due to limitations of its own energy storage,which seriously affects network performance.For the three cases where deployment location is fixed,deployment location is not fixed and unrestricted,deployment location is not fixed and restricted,the specific deployment algorithm is given by integer programming to maximize the charging effect of the entire sensor network area.Finally,the simulation analysis using Matlab shows that compared with the traditional full coverage deployment,the number of chargers needed can be significantly reduced.
