摘要 使用多种无线移动网络连接方法给客户提供网络服务的需求与日俱增,相应的能量耗费率增长问题也随之而来。因此,在异构网络中,降低移动客户端的能耗以及信号干扰将成为研究人员主要的关注点。为此,采用最小化加权成本函数来提高移动用户的能量利用率。考虑到各个要素的权重值,使用了多要素的层次分析法来计算权重。成本函数表示用户对可用基站的成本,包括能效、距离、信号与干扰加噪声比等。此外,基于最小成本值引入了最佳用户关联。仿真结果表明,该优化方案节省了更多的能源,降低了网络信号传输之间的干扰。 The demand for using a variety of wireless mobile network connection methods to provide services to customers is increasing day by day,and the corresponding increase in energy consumption rates also follows.Therefore,in a heterogeneous network,reducing the energy consumption of mobile clients and signal interference will become the main focus of researchers.The research work in this paper aims to improve the energy utilization of mobile users by minimizing the weighted cost function.In order to consider the weight value of each indicator,this article uses a multi-index analytic hierarchy process to calculate the weight.The cost function represents the user's cost to the available base station,which includes energy efficiency,distance,SINR,etc.In addition,this paper introduces the optimized user association based on the minimum cost value.The simulation results show that the optimization method saves more energy and reduces the interference between network signal transmission.
