摘　　要：在无线传感器网络(WSNs)中,数据汇聚是各种应用的基础,其能量消耗也是网络总能耗的主要部分,因此研究能量有效的数据汇聚机制是关键。该文提出了一种"协同簇"的数据汇聚机制(CC-DAM),从理论上完整分析了其数据传输的总能耗,导出了簇内参与协同数据传输的最佳节点数,并论证了其优于传统簇机制的条件;同时,提出了一种基于簇核心的地理位置路由策略,具有能量有效性和好的路由方向性。仿真实验结果表明CC-DAM是一种能量有效的数据汇聚策略,适合无线传感器网络的各种应用。In wireless sensor networks,the data aggregation is the foundation for various applications,and its en-ergy consumption is the main part of the total,so it is an important topic to design the energy efficient data aggregation mechanism.This paper presents a Cooperative Cluster Based Data Aggregation Mechanism（CC-DAM）,analyzes its total energy consumption,and brings forward the optimal number of sensor nodes that should participate in the coop-erative data transmission.The condition under which the new mechanism is more energy-efficient than the traditional cluster mechanism is also reasoned.Furthermore,a routing strategy based on cluster core is put forward,and it is not only energy efficient,but also with good routing direction.The results of experiments show CC-DAM is an en-ergy-efficient data aggregation mechanism and suitable for all kinds of applications of WSNs.
