【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。
【Objective】 To solve the problem of saving energy and prolonging network lifetime, this paper proposes a self-organizing clustering algorithm (DBSOCA) that can effectively reduce the energy consumption of nodes based on analyzing the shortages of typical clustering algorithms. [Method] In this algorithm, the nodes in a cluster choose the cluster head according to the distance between themselves and the base station and ensure that the transmission between the base station and the cluster head and the cluster head can keep a certain distance. 【Result】 The average transmission distance is used to avoid the imbalance of energy consumption due to the different transmission distance of the first cluster. 【Conclusion】 Simulation results show that this algorithm can effectively reduce the energy consumption of the entire network and further extend the life cycle of the network.
