摘　　要：尽管簇路由是缓解无线传感网络(Wireless Sensor Networks,WSNs)能耗问题的有效技术。但是,构建簇本身也消耗能量。为此,提出基于模糊干扰系统的构簇策略。该策略引用复轮,每个复轮含有多个轮,只在复轮开始阶段才构建簇。并依据簇头的剩余能量和距离作为模糊干扰系统的输入,再由模糊干扰系统决策复轮的长度,实现了动态地调整复轮长度,降低构簇能耗。仿真数据表明,该策略能有效地降低能耗,并降低了数据传输时延。Although clustering routing is one of the effective approaches for remitting energy-consumption of a wireless sensor network,but constructing clustering is itself dissipating energy. Therefore,Fuzzy logic-based clustering-Task scheme is proposed in this paper. The proposed scheme used duplicated-round.Each duplicated-round consist of several rounds. Only in start of duplicated-round,the clustering-task is activated. The CH’s residual energy and its distance from base station are used as the inputs of fuzzy logic system,and duplicated-round length is its output,which dynamically adopt the duplicated-round length and reduce the energy-consumption of form clustering. Simulation results reveal the effectiveness of the proposed scheme in reducing the energy-consumption and delay.
