We propose a network-based endpoint admission control system for scalable QoS guaranteed real-time communication services. This system is based on a sink tree-based resource management strategy, and is particularly well suited for differentiated-services based architectures. By performing the admission decision at the endpoints, the flow setup latency and the signaling overhead are kept to a mi...

Review of theoretical models for cost-effectiveness and of procedures currently being used by different levels of decision makers to evaluate the projects or alternatives is the main objective of this article. To come to some conclusion that which theoretical model would be more effective to be applied for allocating the limited resources among different projects. the performance evaluation pro...

Business Process Management Systems (BPMS) is a complex information system that provides designing, administrating, and improving the business processes. Task allocation to human resources is one of the most important issues which should be managed more efficiently in BPMS. Task allocation algorithms are defined in order to meet the various policies of organizations. The most important of these...

In this paper we propose a Two-Tier resource management model for the global Internet. Our solution resembles the current two-tier routing hierarchy and allows individual administrative domains to independently make their own decisions on strategies and protocols to use for internal resource management and QoS support. The aggregate traffic crossing domain borders is served according to relativ...

Many desired features of computing platforms, such as increased fault tolerance, variable quality of service, and improved energy efficiency, can be achieved by postponing resource management decisions from design-time to run-time. While multiprocessing has been widespread in embedded systems for quite some time, allocation of (shared) resources is typically done at design-time to meet the cons...

in the market for factors of production usually the equilibrium will be stablished on the based of the equality between the value of marginal products of output and their relative price level. on the other hand the value of marginal product of output is a function of observed rate productivity of output and the market capacity of factors of production. thus the fluctuation in the rate of produc...

The growing fields of wireless networks and asynchronous transfer mode (ATM) are merging to form wireless ATM networks. This paper addresses dynamic bandwidth allocation, connection admission procedures, routing, and location management strategies in wifeless ATM. More precisely, we investigate the issue of extending the private Network to Network Interface, PNNI, and protocols to support mobil...
