This paper addresses an energy-efficiency (EE) maximized resource allocation (RA) problem for a downlink orthogonal frequency division multiple-access (OFDMA) network, when the system's total power (including transmission power and fixed circuit power) is constrained below a peak value. The EE is evaluated by the number of message bits delivered corresponding to per Joule energy consumed by the whole...
Computational grid is a cooperative computing environment which collects all kinds of high performance software and hardware computing resources distributed in WAN and provides networked computing services. The computational grid systems that have been the focus of much research activities in the past years for controlled sharing of resources across institutional boundaries. Credit is one major concern...
