Resource Allocation problems in edge wireless networks

Abstract: In this talk, we will discuss two problems we have been working on recently.

In the first one, we study the problem of optimal caching of 360-degree video streams. The difference from conventional video is that the video panorama is divided into tiles. Each tile may need to be cached simultaneously at multiple resolutions, since it may appear in different positions at different viewports, and the time proportions of these positions are dictated by users' viewing statistics.

In the second one, we consider the problem of investment and use of shared network infrastructures.
We study the interaction of a set of self-interested, budget-limited Service Providers (SPs), each of which invests a portion of its budget towards building a common network infrastructure, which is then shared among SPs for offering services. SPs pay an infrastructure Operator (IO) for leasing resource slices and then obtain revenue from services. We characterize and study various aspects of the ensuing game.

We will also briefly overview the current research threads of our group spanning areas such as mobile crowdsensing, behavioral science, and recommender systems.

Bio: Iordanis Koutsopoulos is an Associate Professor at the Department of Informatics of Athens University of Economics and Business (AUEB) in Athens, Greece since 2016. He received the Diploma degree in Electrical and Computer Engineering from the National Technical University of Athens (NTUA), Greece, in 1997 and the M.Sc. and Ph.D. degrees in Electrical and Computer Engineering from the University of Maryland, College Park (UMCP), MD, USA, in 1999 and 2002, respectively.

He has served as Assistant Professor (2013-2016) with AUEB, and Assistant Professor (2010-2013) and Lecturer (2005-2010) with the Department of Electrical and Computer Engineering, University of Thessaly. His research interests are in the general area of network control and optimization and on applications of machine learning, with application areas such as mobile crowdsensing, edge computing, online platforms, and the smart energy grid.
