摘要
提出一种基于能量的多跳簇生成(EMHC)算法,根据剩余能量争先原则选择簇首,并采用最小通信代价的多跳簇内结构。通过OMNet++模拟器对算法进行实验,结果表明,EMHC形成的簇首分布较为均匀,可以利用最佳多跳路径节约传输能量,提高网络生存时间,与LEACH和HEED算法相比具有较大优势。
This paper proposes Energy-Based Multi-hop Clustering（EMHC） algorithm which selects cluster heads according to the priority of residual energy and adopts the minimum inner-cluster communication cost structure. Simulations on OMNet＋＋ show that the cluster heads are evenly distributed, and energy is saved to improve the network lifetime by EMHC algorithm. Its performance is superior to LEACH and HEED.
