【摘要】：【目的】针对节省能耗、延长网络生命周期的问题,在分析典型分簇算法不足的基础上,提出了能有效减少节点传输能量消耗的距离均衡的自组织分簇算法(DBSOCA)。【方法】在该算法中,簇内节点依据计算自身与基站的距离来竞选簇首,并确保基站与簇首及簇首间的传输能够保持一定的距离。【结果】用平均传输距离来避免簇首因传输距离的不同而造成能耗的不均衡。【结论】仿真结果证明,该算法能有效地降低整个网络的能耗,进而延长网络的生命周期。
[Abstract]:[objective] to solve the problem of saving energy and prolonging the network life cycle, based on the analysis of the shortage of typical clustering algorithm. A self-organizing clustering algorithm named DBSOCAA is proposed, which can effectively reduce the transmission energy consumption of nodes. [methods] in this algorithm, the nodes in the cluster run for the cluster head according to the distance between themselves and the base station. And ensure that the transmission between base station and cluster head and cluster head can maintain a certain distance. [results] the average transmission distance is used to avoid the imbalance of energy consumption caused by the difference of transmission distance. [conclusion] the simulation results prove that. This algorithm can effectively reduce the energy consumption of the whole network and prolong the lifetime of the network.

【正文快照】： 近些年来在无线传感器网络(WSNs)[1-3]领域中,出现了不少以节省能耗为目的的分簇算法。低能耗自适应聚类算法LEACH[4]是其中最经典的代表,该算法采用几率的方式来选举簇首(Cluster header,CH),通过随机选择簇首的方式节约建立分簇所需的计算时间,缺点是无法保证选举的簇首是最
