摘要
本文介绍了一种基于基带单元(BBU)虚拟化的云无线接入网(C-RAN)架构的新功耗模型。此外，还在BBU池中提出了一个主机服务器(HS)，该服务器承载了一种改进的最佳拟合减少(MBFD)算法，以优化BBU重新配置为合适的远程无线电头(RRHs)。仿真结果表明，与传统网络和最佳拟合减少(Best Fit reduction, BFD)算法相比，MBFD在减少活动bbu数量和降低功耗方面具有更好的效果。
Reducing power consumption by dynamic BBUs-RRHs allocation in C-RAN
In this paper, a new power consumption model for Cloud Radio Access Network (C-RAN) architecture based on virtualization of Base Band Unit (BBU) has been introduced. Moreover, it is proposed a Host Server (HS) in the BBU pool that hosts a Modified Best Fit Decreasing (MBFD) algorithm to optimize reconfiguration of BBUs to proper Remote Radio Heads (RRHs). The simulation results show the MBFD effectively better in decreasing the number of active BBUs and decrease power consumption compared with Best Fit Decreasing (BFD) algorithm and traditional network.
