摘　　要：EEPB算法建链时引入的距离门限值具有不确定性,取值不当会导致相邻节点间产生长链,并且没有最优化链首选择等问题。为此,提出基于三角模融合算子的EETMO算法。以节点剩余能量与节点到基站的距离2个特征参量为依据建立隶属度函数,利用三角模融合算子进行融合判决,根据判决结果选取链首。实验结果表明,该算法在平衡节点能耗和延长网络最大生命周期方面,性能优于EEPB算法。EEPB is a chain-based protocol which has certain deficiencies including the uncertainty of threshold adopted when building chain,the inevitability of long link when valuing threshold inappropriately and the non-optimal election of leader node.Aiming at these problems,an Energy-efficient algorithm based on Triangle Module fusion Operator（EETMO） is proposed.EETMO adopts new method to build chain,and establishes membership functions of nodes residual energy and distance between a node and base station respectively,uses the fusion method of triangle module operator to determine the leader node selection.Experimental results show that EETMO has a better performance than EEPB on balancing energy consumption and prolonging lifetime of Wireless Sensor Network（WSN）.
