摘要

为了解决无线网络能耗和用户体验质量的问题，提出了一种应用于异构无线网络环境的基于多目标优化的联合接入选择和功率分配策略。该策略以最小化系统整体能耗和最大化用户平均体验质量为目标，建立了多目标优化联合分配模型，通过差分进化算法得到联合分配模型的最优解集，并结合 TOPSIS 的方法从最优解集中得到折中的联合分配方案。仿真结果表明，本文所提的策略能够有效地降低系统能耗，并提升用户整体的服务体验。

Abstract

Based on multi-objective optimization

a joint user association and power control scheme was proposed in heterogeneous network environment

aiming to reduce the system energy consumption and improve user quality of experience.The scheme took the system energy consumption minimum and the average user quality of experience maximum as objective functions and translated the joint user association and power control to multi-objective problem.Then

the differential evolution optimization algorithm and TOPSIS algorithm was used to solve the multi-objective problem.Simulation results show that the scheme can efficiently reduce the system energy consumption and improve the user quality of experience.
