| 摘 要： | 降低能耗是无线传感器网络研究中重要内容之一.节点间数据传输能耗很大,合理调节传输功率,对降低网络能耗非常重要.本文引入PID算法,通过调节每个节点传输功率,动态控制整个网络的传输能耗.MATLAB仿真结果显示,该算法在几种不同的部署情况下,比LMA(local mean algorithm)及其它几种方法在网络启动能耗和启动时耗指标下都更为有效.

| Abstract: | Lowing energy consumption is one of the most important research areas in Wireless Sensor Networks(WSNs).Since data transmission between nodes consumes a large amount of energy,proper adjustment of power transmission could contribute much to energy reduction.PID algorithm is introduced to the dynamic control of the entire networks' energy cost by shifting the transmission power of every node.The results of MATLAB simulation are shown that,under a number of diverse disposition cases,our algorithm is more effective than LMA (local mean algorithm) as well as several other algorithms in the start-up energy consumption and coverage time. |
