摘要： 针对无线传感器网络能量受约束的问题,为实现节点均衡能耗,平衡网络簇头分布,并最大限度地延长网络寿命,提出一种基于细胞膜优化算法的无线传感器网络能量均衡分簇协议。细胞膜优化算法具有良好的全局寻优和快速收敛能力,通过浓度与能量因素对节点进行划分,并结合距离因素完成全局均衡分簇,能够解决传感器网络中簇头分布不均匀、全局能耗不均衡等问题。实验结果表明,该协议具有对无线传感器网络进行快速全局均衡分簇的能力,且与LEACH 算法和LEAH-C 算法相比,在均衡节点能耗和延长网络生存周期等方面具有更好的性能。

Abstract: Aiming at energy constrained problems in Wireless Sensor Network(WSN),in order to achieve a balanced energy consumption of nodes,balance cluster heads distribution,and maximize the network lifetime,this paper proposes a WSN energy balanced clustering protocol which is based on the Cell Membrane Optimization(CMO) algorithms. The CMO algorithm has good ability of global optimization,and fast convergence capability. The new clustering protocol divides the nodes through concentration and energy factors. Combined with the distance factor for global clustering balance,it can be a good solution to the uneven distribution for cluster head,imbalanced global energy and other issues. Experiments show that the protocol has the capability of balanced global clustering quickly. Compared with LEACH algorithm and LEACH-C algorithm,it has better performance in terms of balancing power consumption and prolonging the network lifetime.
