| 摘 要： | 传统的LEACH算法因为簇首选举的随机性而导致节点能量分布不均,从而影响网络寿命和系统吞吐量,在此基础之上提出了一种基于自适应退避机制的分簇算法,通过设定一个能量门限来衡量簇首的健康度,并采用退避机制来使那些趋于衰亡的簇首能找到合适的继任者来担当簇首,保证数据传输的可靠性.仿真实验显示,该算法能够较LEACH获得更长的网络寿命,并提高了网络的吞吐量.

| Abstract: | Due to its random selection of clusters,the traditional LEACH protocol definitely results in the unbalanced state of nodes' energy,which shortens the whole network lifetime and decreases the system throughput.A clustering algorithm based on adaptive abdication strategy was proposed.By setting an energy threshold to evaluate the healthiness of clusters,the algorithm enables those dying clusters to pass their status to the suitable successor according to an abdication strategy,which ensures the reliability of... |
