无线传感器网络中基于分层的非均衡分簇算法

降低网络能量消耗、延长网络寿命是无线传感器网络设计的重要目标,分簇是实现该目标的主要方法之一。针对矩形传感器网络,提出一种基于分层的非均衡分簇算法。算法根据节点的能量消耗情况计算出了每层的宽度,可以有效实现网络的能耗均衡。将非均衡分簇算法与LEACH协议进行了比较,仿真实验表明:基于分层的非均衡分簇算法可以更好地实现能耗均衡,能有效延长网络的寿命。

Layer-based unequal clustering algorithm of wireless sensor networks

Reducing energy consumption and prolonging lifetime of the networks are important targets of wireless sensor networks.Clustering scheme is an effective technique to achieve this goal.Aimed at the rectangular sensor networks,a layer-based unequal clustering algorithm is proposed.The width of the layers can be computed according to nodes energy consumption,the energy consumption of the networks can be balanced effectively.The unequal clustering algorithm is compared with LEACH.Simulation results show that layer-based unequal clustering algorithm can better implement energy consumption balance and effectively extend the lifetime of the networks.
