A Novel Cost Optimization Framework for Multi-Cloudlet Environment over Optical Access Networks

Abstract

In the post-4G era, "low latency" has become one of the most important network requirements along with support for ultra-high capacity and ultra-high reliability. This has led to the evolution of "cloudlets" to support similar services provided by legacy cloud technology viz., storage capacity and computational capability. In this paper, we propose a novel framework for cloudlet-empowered-cloud network design and planning, based on optical access infrastructures. Our focus is on network planning to optimize network infrastructure cost by formulating a nonlinear programming model to identify placement locations of cloudlet servers subjected to capacity and latency constraints. We demonstrate ..
