We propose a distributed dynamic frequency allocation algorithm that achieves performance close to that of a centralized optimal algorithm. In our network model, nodes are grouped into a number of clusters. Each cluster chooses its transmission frequency band based on its knowledge of the interference that it experiences. The convergence of the proposed distributed algorithm to a sub-optimal fr...

In this paper we study the scalability issue in the design of a centralized bandwidth broker model for dynamic control and management of QoS provisioning. We propose and develop a path-oriented, quota-based dynamic bandwidth allocation mechanism for efficient admission control operations under the centralized bandwidth broker model. We demonstrate that this dynamic bandwidth allocation mechanis...

Application layer networks are software architectures that allow the provisioning of services requiring a huge amount of resources by connecting large numbers of individual computers like in Grid or Peer to Peer computing Controlling the resource allocation in those net works is nearly impossible using a centralized arbitrator The network simulation project CATNET will evaluate a decentralized ...

Network slicing is a key enabler for providing new services to industry verticals. In order enable network slice provisioning, it important study the type allocation different device types in real industrial case. Furthermore, costs of required virtualization infrastructure need be analyzed various cloud deployment scenarios. this paper, cost model needed provisioning developed and subsequently...

Wireless Mesh Networks (WMNs) built with commodity 802.11 radios are a cost-effective means of providing last mile broadband Internet access. Their multihop architecture allows for rapid deployment and organic growth of these networks. 802.11 radios are an important building block in WMNs. These low cost radios are readily available, and can be used globally in license-exempt frequency bands. H...

Current processor allocation techniques for highly parallel systems are based on centralized front-end based algorithms. As a result, the applied strategies are restricted to static allocation, low parallelism and weak fault tolerance. To lift these restrictions we are investigating a distributed approach to the processor allocation problem in large meshconnected multicomputers. A noncontiguous...

In this article, we propose a semi-distributed resource allocation framework for the resource optimization in multicell uplink cooperative orthogonal frequency division multiplexing systems. Specifically, we model the resource allocation framework as an optimal problem. This optimization problem is divided into two steps. First, using integer programming, we achieve the joint relay selection an...
