In this paper we propose a novel framework for the dynamic allocation of jobs in grid-like environments, in which such jobs are dispatched to the machines of the grid by a centralized scheduler. We apply a new, full resource-driven approach to the scheduling task: jobs are allocated and (possibly) relocated on the basis of the matching between their resource requirements and the characteristics...

It is increasingly difficult to satisfy growing demands for spectrum with the conventional policy of fixed spectrum allocation. To overcome this problem, flexible/dynamic spectrum sharing methods that can significantly improve spectrum utilization of the spectrum have gained increasing interest recently. This paper presents two dynamic spectrum sharing approaches, a centralized and a decentrali...

Internal capital market theory is one of the most essential theories for studying internal management enterprises. It fundamentally solves problem information asymmetry in external and optimizes resource allocation enterprises while reducing transaction costs. This paper analyzes impact endogenous financing from perspective which improve centralized corporate enhance overall value groups.

This chapter studies the problem of decentralized resource allocation among competing users in communication networks. The growth in the scale of communication networks and the newly emerging interactions between administrative domains and end-users with different needs and quality of service requirements necessitate new approaches to the modeling and control of communication networks that reco...

The downlink of a hybrid system with regenerative relaying (cellular extended by means of fixed wireless router) is studied in terms infrastructure costs. Using a static linear cost model, the feasibility of the hybrid system is analyzed by comparing the infrastructure cost of providing a predefined service level with a traditional single hop system and with a hybrid system, respectively. The a...

This paper describes the network architecture and provides a performance analysis of a passive optical network named SONATA, which has been proposed and will be demonstrated in the context of the European Union ACTS Program. In this nation-wide all-optical network, end-terminals access a single passive routing node via PONs using a TDMA/WDMA access scheme based on slot reservations. The central...

The Multi Carrier Code Division Multiple Access (MC-CDMA) system with time division duplex mode, adopting unbalanced slot allocation between uplink and downlink, is a good solution for asymmetric multimedia traffic. A centralized common slot allocation to minimize inter-cell interference is not feasible as neighboring cells may carry different rates of traffic load. In this paper, we investigat...

Computational grids have the potential for solving large-scale scientific problems using heterogeneous and geographically distributed resources. However, a number of the major technical hurdles must overcome before this potential can be realized. One problem that is critical to effective utilization of computational grids and gives a certain Quality of Service (QoS) for grid users is the effici...

Conventional resource management systems use a system model to describe resources and a centralized scheduler to control their allocation. We argue that this paradigm does not adapt well to distributed systems, particularly those built to support high-throughput computing. Obstacles include heterogeneity of resources, which make uniform allocation algorithms difficult to formulate, and distribu...
