为了保证网络运行寿命,避免传统节点选取技术能耗和时延高的弊端,提出一种新的网络拓扑控制的节点稳定性选取技术.构建EETCA网络拓扑结构,研究网络拓扑的控制,控制过程主要包括簇头选择阶段、簇的建立阶段和稳定数据的传递阶段.建立节点选取模型,通过Hopfield网络模型减小检索范围,结合遗传法和Hopfield网络局部搜索法完成网络节点的稳定性选取.采用Hopfield网络局部搜索法生成父代基因库,求出每个染色体的适应度,确定遗传算子,生成子代基因库,得出最优解,获取节点稳定性选取结果.实验结果表明:所提技术能够保证网络使用寿命,且时延和能耗低.%In order to ensure the network operating life and avoid the disadvantages about the high energy con-sumption and high time delay in traditional node selection techniques,a new node stability selection technique of network topology control was proposed. The EETCA network topology structure was set up and researched the con-trol of network topology by this technique. The network topology control process mainly included the cluster-head selection phase,the cluster establishment phase and the stable data transmission. The node selection model was established,and the retrieval range was reduced by Hopfield network model. Combined genetic algorithm with lo-cal search method of Hopfield network,the stability of network nodes was completed. Hopfield network local search method was used to generate the parent gene pool. The fitness of each chromosome was obtained. The ge-netic operator was determined,which generated the filial generation gene pool. The optimal solution and the node stability selection results were obtained. Experimental results show that the proposed technique can ensure the li-fetime of the network. It has the low time delay and energy consumption.
