基于GLV模型的异构网络联合无线资源管理

GLV-based Joint Radio Resource Management in Heterogeneous Wireless Network

为使不同的无线接入网络协同工作,实现异构无线网络的接纳控制,基于生态学种群竞争与异构无线网络资源管理的映射关系,提出了一种分布式联合无线资源管理(JRRM)算法。建立了基于Gause-Lotka-Volterra(GLV)的异构网络业务量预测模型,根据预测的业务量是否达到共存状态来调整网络参数,以使各网络的业务量达到稳定平衡状态。性能分析与仿真结果表明,该算法可以均衡各个网络的业务量,减少竞争对于网络的影响,使不同网络运营商均获得了一定收益。

To make the different radio access networks work together and achieve the admission control in heterogeneous wireless network,based on the mapping relationship of ecological competition and heterogeneous radio resources management,this paper proposes a distributed joint radio resource management（ JRRM） algorithm. It establishes a GLV-based heterogeneous network traffic prediction model. Moreover,it adjusts the network parameters according to whether the predicted traffic achieves coexistence state or not,to achieve the traffic stable equilibrium state. Performance analysis and simulation results show that the algorithm can balance the network traffic,reduce the networks competition effect,and make the profits for different operators.
