Power optimization and interference management in ultra-dense small cell based fifth-generation mobile networks are critical issues. This paper proposes a two-tier micro-femtocell based heterogeneous ultra-dense cellular network system, where femtocell allocation takes place inside the microcell based on user density. The femtocells form groups according to the adjacency and the leader selection of each group is performed using weighted majority game. Dedicated frequency allocation is performed for micro- and femtocell users though the leader of each femtocell group allocates frequencies to its follower femtocells based on auction game. Agilent EXG vector signal generator N5172B, EXA vector signal analyzer 9010A, and Agilent signal studio software are used for experimental purpose for performance evaluation of the proposed network. According to the simulation results, the proposed network decreases power transmission by 23%-41%, improves signal-to-interference-plus-noise ratio by 12%-39% and spectral efficiency by 10%-37% than the existing competing heterogeneous cellular network systems.

WmA-MiFN：基于加权多数和拍卖博弈的绿色超密集微型毫微微小区网络系统

基于超密集小型小区的第五代移动网络中的功率优化和干扰管理是关键问题。本文提出了一种基于两层微微蜂窝基站的异构超密集蜂窝网络系统，其中，微蜂窝基站根据用户密度在微蜂窝内部进行分配。毫微微小区根据邻接关系形成组，并且使用加权多数博弈执行每个组的领导者选择。尽管每个毫微微小区组的领导者都会根据拍卖游戏为自己的跟随者毫微微小区分配频率，但仍会为微型和毫微微小区用户执行专用的频率分配。安捷伦EXG矢量信号发生器N5172B，EXA矢量信号分析仪9010A和安捷伦Signal Studio软件用于实验目的，用于评估所建议网络的性能。
