Stochastic Optimization and Future Wireless Networks
Abstract: Wireless networks are permeated by uncertainty, and meeting the many objectives of modern and future wireless networks requires a stochastic orientation. In this talk, we will describe the tools of stochastic optimization and some of the motivations for using this set of tools to formulate and solve problems in wireless networking. Then we will examine two coverage problems using a stochastic optimization frame. In the first problem, we look at the challenge of covering users in an indoor space using a set of directional millimeter wave access points, given that user orientations are stochastic and that millimeter wave channels are potentially blocked by human bodies. In the second problem, we look at the construction of a virtualized wireless network and how a metric from stochastic geometry can be adapted to frame (and later solve) this problem.
