基于修剪算法的无线传感器网络能量消耗研究
|
摘要
无线传感网络有大量的传感器节点组成,所以在无线传感网络中传感器节点的能量消耗是主要的能量消耗部分。基于分簇协议引起的负载不均衡现象,采用修剪技术对节点的位置、担任簇头节点的次数和剩余能量三者进行加权和分析的这种能量均衡算法,采用动态调整机制选择簇头节点。实验结果表明该算法增加传感器节点的使用时间,有效延长无线传感网络的寿命。
Wireless sensor networks have a large number of sensor nodes,so the energy consumption of sensor nodes is the main energy consumption part in wireless sensor networks. Clustering protocol may cause load imbalance in this kind of network,this is the reason why the pruning technique is used to weigh and analyze the location of the nodes,the number of cluster head nodes and the remaining energy.The energy balancing algorithm uses dynamic adjustment mechanism to select the cluster head node.Experimental results show that the algorithm increases the usage time of sensor nodes and prolongs the lifetime of wireless sensor networks.
