This article provides an overview of a network-based model of power consumption in Internet infrastructure. This model provides insight into how different parts of the Internet will contribute to network power as Internet access increase over time. The model shows that today the access network dominates the Internet's power consumption and, as access speeds(More)
In this paper, we present a new method for the estimation of blocking probabilities in bufferless optical burst or packet switched networks. In such networks, deflection routing is used to reduce blocking probability. However, it requires certain wastage due to trunk reservation that must be used to avoid instability. We provide a wide range of simulation(More)
| Network-based cloud computing is rapidly expanding as an alternative to conventional office-based computing. As cloud computing becomes more widespread, the energy consumption of the network and computing resources that underpin the cloud will grow. This is happening at a time when there is increasing attention being paid to the need to manage energy(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)
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)
As Cloud computing is being adopted widely and usage of internet services is increasing day by day, which gives rise to built large scale data centers. In cloud computing, a lot of research has been done on energy saving programs for reducing the energy consumption of large scale data centers. As large scale data centers consumes large amount of electrical(More)
Network based cloud computing is an alternative to office-based computing. As cloud computing is expanding day by day, energy consumption within cloud is also growing. So there is a need for the management of energy consumption in technology (information and communication) section. Data centers have received more attention in case of energy consumption.(More)
