This paper presents a novel architecture called the MetaGrid based on Grid computing concepts for resource provisioning for wide-area network-enabled applications. Resource provisioning for wide-area applications can involve coordinated allocation of computing and communication resources. A Grid computing systems provides a virtual framework that facilitates controlled resource sharing among di...

Bandwidth transaction service is emerging as a network resource management service among IP network service providers and operators. This paper presents the design of IP-based the transaction-oriented services architecture, called COPIN (Cross-Network Open Provisioning Intelligent Network), and supporting protocols that allow open interfaces and dynamic provisioning across IP QoS interconnections.

Urbanisation and agriculture cause declines for many wildlife, but some species benefit from novel resources, especially food, provided in human-dominated habitats. Resulting shifts in wildlife ecology can alter infectious disease dynamics and create opportunities for cross-species transmission, yet predicting host-pathogen responses to resource provisioning is challenging. Factors enhancing tr...

Future Wavelength-Division Multiplexing (WDM) networks should not only support flexible resource-provisioning, but also transport various services with regulated end-to-end delay. In large-scale backbone networks with dynamic lightpath provisioning, the resource reservation overhead is high due to the latencies involved, thus limiting the capability of end-to-end delay guaranteed service provis...

Cloud computing changed the way of computing as utility services offered through public network. Selecting multiple providers for various computational requirements improves performance and minimizes cost of cloud services than choosing a single cloud provider. Federated cloud improves scalability, cost minimization, performance maximization, collaboration with other providers, multi-site deplo...

The aim of Green Cloud Computing is to achieve a balance between resource consumption and quality of service. In order to achieve this objective and to maintain the flexibility of the Cloud, dynamic provisioning and allocation strategies are needed to manage the internal settings of the Cloud, addressing oscillatory peaks of workload. In this context, we propose strategies to optimize the use o...

Wireless mesh networks are now being used to deploy radio coverage in a large variety of outdoor applications. One of the major obstacles that these networks face is that of providing the nodes with electrical power and wired network connections. Solar powered mesh nodes are increasingly used to eliminate the need for these types of connections, making the nodes truly tether-less. In these type...

Providing end-to-end performance guarantees for QoS-based services, such as interactive voice and video, is a challenging task in the current Internet. In most cases, it involves the cooperation of multiple administrative domains, for the correct resource provisioning along the end-to-end path. Although some QoS standards have emerged in the last years, together with a trend for covering Intern...

Efficiently operating and managing large scale distributed and federated systems is an extremely challenging problem. Current solutions are a combination of centralized management and significant over-provisioning of the infrastructure. With the explosion of new resource-intensive media applications and services, over provisioning of the infrastructure is no longer a viable option. Timely and a...

In the future, we are likely to see a tremendous rise in mobile computing and communications as ubiquitous applications incorporate multimedia information. These mobile multimedia applications will have QoS requirements; resource provisioning algorithms utilize current system resource availability information to ensure that these applications meet their QoS requirements. Information collection ...
