Abstract
The rapid growth of data service promotes the construction of the electric power telecommunication in smart grids. With the objective of energy savings, we determine the optimal location of the data center with the minimal energy cost within all possible positions. An Integer Linear Program (ILP) is formulated and we also propose the corresponding algorithms, mainly including Green Optical Bypass Energy Saving Grooming Algorithm (GOBEGA) and Green Non-Bypass Energy Saving Grooming Algorithm (GNBEGA). Simulation results demonstrate that the proposed algorithms have the good performance of energy savings, and GOBEGA has the lower energy cost compared with GNBEGA.
