Virtualization Technology has been employed increasingly widely in modern data centers in order to improve its energy efficiency. In particular, the capability of virtual machine(VM) migration brings multiple benefits for such as resources(CPU, memory, et al.) distribution, energy aware consolidation. However, the migration of virtual machines itself brings extra power consumption. For this reason,...
In this paper, we discuss resource management in modern wireless communications with the objective of minimizing power consumption, and carry out an analysis of simultaneous transmission and orthogonal transmission schemes in an FDMA (Frequency Division Multiple Access) framework. Based on a two-link line model with path-loss only, the performance of these two schemes for network power minimization...
