Abstract: 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).

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。
