摘　　要：将传感器节点的剩余能量和通信代价这两个参数作为参考依据,提出了角色成员关系能量算法(Role energy-efficient membership,REEM)。该算法构建了节点之间的角色关系和成员关系,并且通过这两层关系进行信息的传输。节点的剩余能量和汇聚节点的通信代价是角色和成员关系的主要依据。通过传感器节点的角色和成员关系的互相转换,使得整个网络能耗均衡。尽可能地利用节点的剩余能量,延长网络运行的生命周期,最大程度地进行信息搜集。A REEM algorithm is proposed,which takes the residual energy and communication cost of sensor nodes as two parameters.The role-relationship and member-relationship between nodes are constructed in the algorithm,and information transformation is conducted through these two relationships.The role-relationship and member-relationship are dependent on the residual energy and communication cost of the nodes.The energy-balance of the wireless sensor network is obtained by the conversion of the role-relationship and member-relationship.The algorithm can make use of the node residual energy as much as possible,extend the life cycle of the network,and realize maximum information collection.
