A power adjustment scheme applied to WSN node

功率调整控制技术是无线传感器网络应用研究中关注的重要问题之一,它对WSN节点的生存时间、通信状况及能量利用等方面有着显著的影响。提出了一种适用于无线传感器网络的功率自适应调整方案,通过动态判断预设阈值调整终端节点的功率值获得相对合适的发射功率。实验结果表明相对于单一固定发射功率模式,该方案具有较为明显的优化效果。

Power adjustment and control technology is one of the core issues in applied research on wireless senor network. It has a significant influence utilization of the WSN node. This paper proposes a on time-to-live, communication condition and energy utilization of the WSN node. This paper proposes a plan of adaptive power adjustment which applies to wireless sensor network. The relatively appropriate transmission power is acquiredby the method of dynamical judgment in the preinstall threshold, which causes adjustment in the power value of the terminal node. The result shows that compared to single fixed mode of transmit power, this plan has relatively more obvious optimization.
