摘要:

分析自然能收集的特点,提出一种基于自然能收集预测的无线传感器网络分簇路由算法。在簇头选取阶段,对自然能收集值进行预测,使预测值大且剩余能量多的节点更有可能担任簇头,其余节点加入通信代价小的簇。仿真实验结果表明,与现有其他算法相比,该算法改善了网络能量的均衡性,提高了网络节点的平均能量水平。

Abstract:

This paper analyzes the characteristics of ambient energy harvesting,and proposes a Wireless Sensor Network(WSN) clustering routing algorithm based on ambient energy harvesting prediction.In cluster head selection stage,it predicts the coming ambient energy,nodes with higher prediction value and more residual energy are more likely to act as cluster heads.Other nodes join the cluster according to the communication cost.Simulation results show that compared with the existing algorithms,the proposed algorithm can improve network energy balance and improve the average energy level of network nodes.

Key words: ambient energy harvesting, Wireless Sensor Network(WSN), clustering routing, ambient energy prediction, solar energy
