PSO-based Double Cluster-Heads Clustering algorithm 分簇算法 ; 双簇头分簇算法
Based on the study of LEACH, a clustering hierarchy algorithm named cluster heads optimized algorithm was proposed.
基于对LEACH等算法的研究，提出一种传感器网络分簇算法———簇头优化分簇算法。
However, the cluster heads close to the sink node lead to energy failure for transmit large amount of data, resulting in "energy hole" phenomenon.
但是，由于靠近汇聚节点的簇头需要转发大量数据，容易导致能量快速衰竭而失效，造成“能量空洞”现象。
The two layer cluster heads were selected by base station in terms of residual energy of node and distance between cluster heads and base station.
由基站依据节点剩余能量和簇头与基站的距离分别选出二层簇头，簇内节点利用单跳和多跳模式与簇头进行通信。
