Package Assignment and Processing Resource Allocation for Virtual Machines in C-RAN


A. Zamani, S. Shojaee, R. Mathar, A. Schmeink,


        Cloud-Radio Access Networks (C-RANs) are known for their potential to accommodate the heavy processing required by the exponentially increasing data traffic. Thanks to virtualization techniques, the baseband processing in C-RANs, can now be performed on virtual machines (VMs) at the central unit (CU). This is a priceless tool for improving the processing efficiency, as it provides the opportunity for dynamic allocation and sharing of processing resources. In this work, we investigate the assignment of processing jobs and the allocation of resources among the virtual machines, while reducing the overall power consumption of the VMs. Furthermore, the developed model also accounts for communication overhead, which may incur due to package dependencies. The performance of the proposed technique is investigated with varying system constraints and the obtained results demonstrate the potential power savings made possible using the proposed method.
