摘要

提出基于传输功率控制器(PTPC)的无线传感器网络(WSNs)的功率控制算法

记为PTPC-PM

算法依据无线信道变化情况

动态地调整传输功率等级。并通过基于PowWow软件的真实WSNs平台进行实验

将节点安装于机器人

并引用CC2420RF作为发射器。实验数据表明:提出的PTPC-PM算法能够有效地维持较高的数据包传输率

并降低能耗。当机器人的移动速度为0.4 m/s时

PTPC-PM算法每传输一个数据包的能耗比固定传输功率算法下降了23.6%。

Abstract

In wireless sensor networks（ WSNs）

the greater the node transmission power

the better the connectivity of network is. However

the energy consumption is more enormous. Therefore

predictive transmission power controller-based power management（ PTPC-PM） approach is proposed. The main objective of PTPC-PM is to dynamically adjust the transmission power level according to the wireless channel variations. Experiments are performed on real WSNs platform based on PowWow

which is based on a CC2420 RF transceiver

and mobile node attached to robot. The simulation results show that PTPC-PM algorithm can keep a high packet delivery ratio

and reduce energy consumption. When robot is moving at a speed of 0. 4 m/s

compared with fixed TX power policy

energy consumption of PTPC-PM algorithm is reduced 23. 6 %.
