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。[Purposes]Aiming at the problem of saving energy and prolonging the life cycle of the network,this paper proposes a Distance-Balanced Self-Organization Clustering Algorithm（DBSOCA）which can effectively reduce the energy consumption of node transmission based on the deficient analysis of typical clustering algorithm.[Methods]In this algorithm,a sensor node will calculate its distance from the base station（BS）and use this distance as a factor for selecting the CH to ensure an even distance between the BS and the CHs and between each CHs.[Findings]The even transmission distance was used to avoid unequal energy consumption caused by different transmission distances between the CHs.[Conclusions]The simulation results demonstrate that the algorithm can effectively reduce the energy consumption of the whole network and prolong the lifetime of the network.
