摘要

传感器节点的能量消耗是无线传感器网络设计中的一个重要问题。由于大多数节点都是微型电池供电，因此能量消耗的增加将导致节点寿命的缩短。无线传感器网络中用于降低能耗的机制之一是传输功率控制。以恒定/最高功率水平传输会导致能量浪费，也会增加网络中干扰的机会。因此，通过控制传输功率，可以节约能量。本文采用PID反馈机制实现了一种动态传输功率控制方案。我们使用PID机制控制RSSI和LQI，目的是在不影响链路质量的情况下降低能耗。基于仿真和实验结果对其性能进行了评价。此外，我们将其与著名的自适应传输功率控制算法(ATPC)进行了比较。

Dynamic transmission power control in wireless sensor networks using P-I-D feedback control technique

Energy consumption of Sensor Nodes is an important issue in Wireless Sensor Network design. Since most of the nodes are minuscule battery operated, increased energy consumption will lead to reduced life time of nodes. One of the mechanism used in WSN for reducing energy consumption is the Transmission Power Control. Transmitting at a constant / highest power level leads to energy wastage and also increases the chances of interference in the network. Hence, by controlling the transmission power, energy can be conserved. In this paper we implement a dynamic transmission power control scheme using PID feedback mechanism. We control the RSSI and LQI using PID mechanism with an aim of reducing the energy consumption without compromising link quality. Performance has been evaluated based on both simulation and experimental results. In addition, we compare it with the well known Adaptive Transmission Power Control Algorithm (ATPC).
