异构蜂窝网络中能效优先的用户关联机制
Energy Efficiency First User Association Mechanism in Heterogeneous Cellular Networks
摘要
Abstract
In order to improve the energy efficiency of heterogeneous cellular networks, a collaborative optimization algorithm of user association and power control based on effective rate weight is proposed.A two-level iterative algorithm is designed to calculate the user association index and the optimal transmission power.In the case of constant power, the problem of total ratio form is transformed into a polynomial form in outer loop, and the optimal user association index is obtained.The transmission power of base station is allocated by Newton method in inner loop.Experimental results show that compared with MSUA, MSUUA and other algorithms, this algorithm has higher energy efficiency, and can make more users associated with the micro-base station.关键词
