The inter-domain QoS control employing a session-based resource management capability of next generation networks (NGN) is demonstrated for the first time. For a video-on-demand application, the extended resource and admission control function (RACF) is applied and the resource reservation over different NGN-domains is successfully conducted.
In this paper, we propose new methods to reduce the handoff blocking probability in LTE wireless networks. This reduction is based on an adaptive call admission control scheme that provides quality of service (QoS) guarantees and gives the priority of handoff call (HC) over new call (NC) in admission. The performances of the proposed schemes are compared with other method by simulation. Our new method...
In this paper, we propose a set of dimensioning rules, which deliver high quality session-based services over an NGN network based IP/MPLS transport infrastructure. In particular, we develop a detailed dimensioning methodology for achieving a target QoS requirement, expressed in terms of per-service traffic flow throughput and delay. The proposed methodology outlines an optimal equipment allocation...
IEEE P1900.4 is an emerging standard for optimized radio resource utilization where cognitive radio technologies are used for efficient spectrum utilization. In this paper, we design and implement a cognitive wireless network system based on open documents of IEEE P1900.4, and evaluate its performance using UDP streaming and HTTP download. Our experiments show interesting results that total network...
In this paper, we introduce a pricing model that ensures efficient resource allocation that provides guaranteed quality of service while maximizing profit in multiservice networks. Specifically, a dynamic allocation policy is examined that relies on online measurements while each service class operates under a probabilistic bound delay constraint. We present a rigorous analysis of the properties of...
As Grid networks grows, the complexity of resource management in Grid networks dramatically increases. To manage the Grid resources efficiently, policy based resource management system is suitable. However, the policy which made at a moment could not be appropriate to other time because the condition of the grid resources with time space changes. Thus, in this paper, we propose asynchronous policy-based...
