Device-to-device (D2D) communication has become a key technology in the fifth-generation cellular networks. Resource allocation is critical to ensure satisfactory performance. However, most existing resource allocation policies focus on delay-unaware performance metrics, such as throughput and power consumption, thus being effective only in delay-insensitive scenarios. To overcome this problem, in...
In this paper, a scenario was considered that cellular user equipments (UEs) and device to device (D2D) communication pairs exist in a full duplex cell. Limited frequency resources are shared by a large number of UEs, and complex interference is introduced due to resource sharing between uplink, downlink UEs and D2D links. To manage the resource and achieve the maximum total system capacity, a non-deterministic...
The increasing VM density in cloud hosting services makes careful management of physical resources such as CPU, memory, and I/O bandwidth within individual virtualized servers a priority. To maximize cost-efficiency, resource management needs to be coupled with the revenue generating mechanisms of cloud hosting: the service level agreements (SLAs) of hosted client applications. In this paper, we develop...
This paper studies the allocation of information flows in noiseless, memoryless communication networks in the presence of omniscient Byzantine adversary. In such networks, adversary may maliciously modify some edge-flows, and legitimate users should resort to network error correction strategies to transmit data reliably. Unlike prior papers, which focused on the capacities of the networks, we consider...
Resource discovery is an important aspect of computational Grid. Locating resources in a Grid environment is difficult because of the geographic dispersion and dynamic nature of its resources. In this paper, a center-distributed virtual community model is designed. Based on his model, a novel grid resource discovery method is presented. Its simulation experiment shows the present algorithm can solve...
In service oriented grid environment, quality of service (QoS) support becomes more and more important. In this paper, we propose a QoS management framework which is based on class of service (CoS) for grid services, called CQEF. By using CoS instead of SLA in grid environment, grid service users and providers will no longer need to negotiate for a complex SLA. This will reduce the overhead effectively...
One of the most important goals of data-center management is to reduce cost through efficient use of resources. Virtualization techniques provide the opportunity of carving individual physical servers into multiple virtual containers that can be run and managed separately. A key challenge that comes with virtualization is the simultaneous on-demand provisioning of shared resources to virtual containers...
Virtual Machines are becoming increasingly valuable to resource consolidation and management, providing efficient and secure resource containers, along with desired application execution environments. This paper focuses on the VM-based resource reservation problem, that is, the reservations of CPU, memory and network resources for individual VM instances, as well as for VM clusters. In particular,...
