可充电无线传感网络

Rechargeable Wireless Sensor Network

针对无线传感网络(WSN)中电池能量有限的问题,提出了一种基于低功耗自适应集簇分层型协议(LEACH)算法的支持无线充电的传感网络模型。首先,通过磁谐共振原理构建了传感节点充电与接收功率的模型;然后,用Matlab软件对LEACH算法进行仿真;最后,将LEACH算法与无线充电相结合,并在此基础上提出一种仅进行一次分簇的新算法NewLEACH算法。实验结果表明,与传统LEACH算法相比,新算法可以有效提高WSN的生命周期和网络吞吐量。

In view of the limited battery energy in Wireless Sensor Networks （WSN）, this paper proposes a wireless sensor network model supporting wireless charging based on Low Energy Adaptive Clustering Hierarchy （LEACH） algorithm. Firstly, the model of charging and receiving power of sensor nodes is constructed by the principle of magnetic resonance. Then MATLAB is used to simulate the routing protocol algorithm of LEACH. Finally, combining the LEACH algorithm and wireless charging, we propose a new algorithm called New LEACH, which only performs one time clustering. The experimental results show that compared with the traditional LEACH algorithm, the new algorithm can effectively improve the life cycle and network throughput of WSN.
