Offloading to external extra resources total or part of the workload generated by applications running on mobile handsets has been proposed as a way to enhance mobile user quality of experience. However, allocating offloading requests to virtual machines (VMs) is one of the most challenging problems in the cloud computing domain area. In this paper, we consider a Cloud Radio Access Network (C-RAN)...
Cloud Radio Access Network (C-RAN) is a novel mobile network architecture that brings baseband processing units (BBUs) of a set of base stations into a central server keeping only remote radio heads (RRHs) at the cell sites. Because of their limited resources, running sophisticated applications on mobile handsets could result in poor performances and shortened battery lifetime. One promising solution...
Cloud Radio Access Network (C-RAN) is a novel mobile network architecture which is deemed to be one of the most promising evolution trends towards future networks. The basic concept of cloud-RAN is to separate the digital baseband processing units (BBUs) of conventional cell sites, from the Radio Remote Heads (RRHs), and move them to the cloud (BBU pool) for centralized signal processing and management...
The proliferation of mobile handsets has undoubtedly spurred on developers to build a large variety of applications that allow users to better exploit their powerful devices. However, running multiple sophisticated applications could result in poor performances and shortened battery lifetime. Mobile data offloading to edge cloud offers a promising solution to enhance both QoS and battery life of mobile...
Mobile communication systems have evolved considerably in recent years encouraging the deployment of multiple systems or multi-cellular technology. Quality of service (QoS) offered to mobile users improves from one system to another for example 4G systems, offer better QoS than that offered by 3G and 3.5G systems. In addition, 4G systems such as LTE (Long Term Evolution) can expand cellular coverage...
