Cognitive Radio: Brain-Empowered Wireless Communications
, 2005
"... Cognitive radio is viewed as a novel approach for improving the utilization of a precious natural resource: the radio electromagnetic spectrum. The cognitive radio, built on a software-defined radio, is defined as an intelligent wireless communication system that is aware of its environment and use ..."

the discussion of interference temperature as a new metric for the quantification and management of interference, the paper addresses three fundamental cognitive tasks. 1) Radio-scene analysis. 2) Channel-state estimation and predictive modeling. 3) Transmit-power control and dynamic spectrum management
Adaptive control of virtualized resources in utility computing environments
- In European Conference on Computer Systems
, 2007
"... Data centers are often under-utilized due to over-provisioning as well as time-varying resource demands of typical enter-prise applications. One approach to increase resource uti-lization is to consolidate applications in a shared infrastruc-ture using virtualization. Meeting application-level quali ..."

in other tiers. In this paper, we develop an adaptive resource con-trol system that dynamically adjusts the resource shares to individual tiers in order to meet application-level QoS goals while achieving high resource utilization in the data cen-ter. Our control system is developed using classical control
Efficient Management of Data Center Resources for Massively Multiplayer
"... (MMOGs) can include millions of concurrent players spread across the world. To keep these highly-interactive virtual environments online, a MMOG operator may need to provision tens of thousands of computing resources from various data centers. Faced with large resource demand variability, and with m ..."

, and with misfit resource renting policies, the current industry practice is to maintain for each game tens of self-owned data centers. In this work we investigate the dynamic resource provisioning from external data centers for MMOG operation. We introduce a novel MMOG workload model that represents the dynamics
Automatically parcellating the human cerebral cortex.
- Cereb. Cortex

Automated control of multiple virtualized resources
, 2008
"... Virtualized data centers enable sharing of resources among hosted applications. However, it is difficult to satisfy servicelevel objectives (SLOs) of applications on shared infrastructure, as application workloads and resource consumption patterns change over time. In this paper, we present AutoCont ..."

Control, a resource control system that automatically adapts to dynamic workload changes to achieve application SLOs. AutoControl is a combination of an online model estimator and a novel multi-input, multi-output (MIMO) resource controller. The model estimator captures the complex relationship between
InterCloud: Utility-Oriented Federation of Cloud Computing Environments for Scaling of Application Services
- Proceedings of the 10th International Conference on Algorithms and Architectures for Parallel Processing (ICA3PP 2010
"... Abstract. Cloud computing providers have setup several data centers at different geographical locations over the Internet in order to optimally serve needs of their customers around the world. However, existing systems do not support mechanisms and policies for dynamically coordinating load distribu ..."

Further, the Cloud computing providers are unable to predict geographic distribution of users consuming their services, hence the load coordination
Dynamic resource allocation and power management in virtualized data centers
- in Network Operations and Management Symposium (NOMS), 2010 IEEE
, 2010
"... Abstract—We investigate optimal resource allocation and power management in virtualized data centers with time-varying workloads and heterogeneous applications. Prior work in this area uses prediction based approaches for resource provisioning. In this work, we take an alternate approach that makes ..."
