For processing large amounts of data, management and switching of communications may contribute significantly to energy consumption and cloud computing seems to be an alternative to office-based computing. ABSTRACT | Network-based cloud computing is rapidly expanding as an alternative to conventional office-based computing. As cloud computing becomes more(More)
he Internet has become an integral component of the economies of all developed and developing nations. The virtual cycle of improvements in telecommunications supporting economic growth, which, in turn, supports growth in telecommunications infrastructure has served many nations very well. However, this cycle cannot continue without end because all(More)
—We develop a new analytical model for the estimation of blocking probabilities in OPS and OBS networks. The model is used to analyze the performance of a new deflection method that uses multiple wavelength channel reservation thresholds, and gives network designers greater control over the performance of the network. The accuracy of the analytical model is(More)
— We consider a telecommunication competition model involving an incumbent and one or more new entrants who only choose to serve the most profitable traffic. The contribution of this paper is a new analysis that studies the effect of traffic shifts, which are common in the Internet era, on the distribution of market share. Introducing and using a new(More)
— One promising approach to Peak to Average Power Ratio (PAPR) reduction for Orthogonal Frequency Division Multiple Access (OFDMA) is the use of reserved tones, which are modulated so as to reduce the PAPR. One problem with this approach is the computationally efficient determination of reserved tone signals that best reduce the PAPR. In this paper we(More)
