基于传感器网络能量均衡分簇算法仿真研究

研究传感网络能量均衡分簇延长网络寿命问题。针对LEACH算法中簇首分布不均及簇首与基站一跳通信能耗大的问题,造成网络簇头的不均匀分布带来的能耗不均衡问题以及簇头的瓶颈等,为了解决上述问题,提出了一种基于能量高效的无线传感器网络分簇路由算法。算法首先在簇头选择过程中利用节点的能量、邻节点数以及每一轮中簇头的个数等参数设置节点当选簇头的优先度,使簇头均匀地分布在网络中;在簇的组建过程中利用能量参数设置簇的重建条件,达到减小簇的重建频率的目的。

Sensor Network Based on Energy Balanced Clustering Algorithm

the study of sensor network energy balanced clustering to prolong the network lifetime problem.In the LEACH algorithm,the cluster head uneven distribution and cluster heads and base jumping communication problems of big energy consumption,causing the network cluster head in the uneven distribution of the problem of unbalanced energy consumption as well as the cluster head bottleneck,in order to solve the above problem,proposed one kind based on the energy efficient cluster-based routing algorithm for wireless sensor networks.The algorithm first in the cluster head selection process using the energy of the node,neighbor nodes and each round of cluster head node is elected the number of parameter settings of cluster head priority,so that the cluster head is uniformly distributed in the network;in the process of the formation of clusters using the energy parameter setting cluster reconstruction condition,to reduce the the reconstruction of frequency of the cluster.Simulation results show that the improved algorithm can not only improve the network,the energy utilization rate,improve the stability of the network,but also can balance the network energy consumption,prolong the network life.
