基于拍卖的混合接入异构网络频谱共享
|
摘要
针对Overlay与Underlay模式的传统频谱共享系统网络效益较低的问题,提出了一种基于拍卖机制的频谱共享。当宏用户靠近飞蜂窝接入点时,飞蜂窝接入点与宏用户之间的链路性能比宏基站至宏用户的性能要好。此时宏基站希望将该用户卸载至飞蜂窝网络中,获得更好的通信服务质量的同时还能为宏基站节约能量。在保证飞蜂窝网络授权用户的QoS前提下,为激励网络内的混合接入,宏基站将自己的剩余频谱供飞蜂窝接入点使用,并对飞蜂窝接入点进行补偿。每个飞蜂窝接入点独立地决定自己的竞价,宏基站根据收集到的竞价决定最优分配策略。提出的基于拍卖机制的混合频谱共享能够使异构网络中的宏基站和飞蜂窝接入点的效用函数最大。并且补偿函数的引入能更好地激励飞蜂窝采用混合接入模式。
A hybrid spectrum sharing algorithm based on auction mechanism is proposed to improve the network efficiency in hybrid spectrum model. When the Macro User Equipments(MUEs)are close to the Femto Access Points(FAPs), the link between the FAPs and the MUEs is better than the link between the Macro Base Station(MBS)and the MUEs. So the MBS will like offload MUEs to the femtocell networks to achieve better quality of communication service and save energy for the MBS. Ensuring the quality-of-service requirement, the MBS gives the remaining spectrum to the FAPs and MBS pays the compensation fee to the FAPs for serving the additional MUEs. Each FAP determines its bid independently,The MBS determines the optimal allocation strategy according to bids. The proposed auction for motivating the hybrid access in the heterogeneous networks results in a win-win solution since both utilities of the MBS and FAPs are maximized. The compensation is used, which can encourage hybrid access in the heterogeneous networks effectively.
