The necessity of the use of several mobile services increases every day. This requires the consumption of energy rates. Hence, minimizing the energy and interferences of mobile users are major concerns of Heterogeneous Networks (HetNet). This paper aims to improve the energy of mobile users by minimizing a weighted function. To consider significant weights values, we have exploited the multicriteria AHP method. The cost function represents the cost of users toward available BS. It includes the essential criteria influencing energy consumption. Moreover, we introduce an optimal user association based on their minimal cost values. Simulation results prove that the optimal method has saved more energy and reduced network interferences.

异构网络能效和干扰缓解的用户关联策略

每天增加使用几种移动服务的必要性。这需要消耗能量。因此，最小化移动用户的能量和干扰是异构网络（HetNet）的主要关注点。本文旨在通过最小化加权函数来提高移动用户的能量。为了考虑重要的权重值，我们利用了多准则AHP方法。成本函数表示用户对可用BS的成本。它包括影响能耗的基本标准。此外，我们基于其最小成本值引入了最佳用户关联。仿真结果表明，该优化方法节省了更多的能源，减少了网络干扰。
