Cherish Every Joule: Maximizing Throughput With an Eye on Network-Wide Energy Consumption

Free registration required

Executive Summary

Conserving network-wide energy consumption is becoming an increasingly important concern for network operators. In this paper, the authors study network-wide energy conservation problem which they hope will offer insights to both network operators and users. In this paper, they study how to maximize throughput under a network-wide energy constraint. They formulate this problem as a Mixed-Integer Non-Linear Program (MINLP). They propose a novel piece-wise linear approximation to transform the nonlinear constraints into linear constraints. They prove that the solution developed under this approach is near-optimal with guaranteed performance bound. They generalize the problem in the first part by exploring throughput and network-wide energy optimization via a multi-criteria optimization framework.
