Kshitiz Verma, Shmuel Zaks, Alberto Garcia-Martinez

TL;DR
This paper proposes a cost-effective, energy-efficient access network design for developing countries, modeling user access patterns, formulating an NP-hard optimization problem, and providing a heuristic that reduces energy use by up to 22%.
Contribution
It introduces a novel network design model tailored for developing regions, including a heuristic solution and real-world evaluation, to minimize costs and energy consumption.
Findings
Energy consumption reduced by up to 22%
Design cost offset within less than a year
Effective in residential and office environments
Abstract
Internet is growing rapidly in the developing world now. Our survey of four networks in India, all having at least one thousand users, suggest that both installation cost and recurring cost due to power consumption pose a challenge in its deployment in developing countries. In this paper, we first model the access design problem by dividing the users in two types 1) those that may access the network anytime and 2) those who need it only during office hours on working days. The problem is formulated as a binary integer linear program which turns out to be NP-hard. We then give a distributed heuristic for network design. We evaluate our model and heuristic using real data collected from IIT Kanpur LAN for more than 50 days. Results show that even in a tree topology -- which is a common characteristic of all networks who participated in our study, our design can reduce the energy…
