Wireless networks have been evolving towards great heterogeneity of radio access technologies, spectrum usage regimes, and resource ownership models. This kind of heterogeneity, combined with densification and greater decision-making autonomy for wireless devices, make game theory especially suited to model such systems. Game theory allows us to predict the outcomes of autonomous decisions by intelligent players (in our case, radios), as well as to design resource usage etiquettes in wireless networks that will lead to desirable outcomes. In this talk, we will outline some ways in which cooperative and non-cooperative game theory can help us understand the complex interactions that will characterize future wireless networks. We will discuss the use of game theory in a variety of scenarios, including dynamic sharing between incumbents and secondary users of spectrum, device-to-device communications, and resource sharing among mobile operators.
Historically, optimization tools have been largely applied to design and operate electricity systems. A typical problem is the so-called “Unit-Commitment” [Tahanan2015]. It consists in scheduling at a minimal cost electricity production units – often before real-time – to satisfy the equality constraint between production and – often forecasted – consumption at all time. Now, the context in electricity systems is rapidly changing, leading to more competition between – newly created – stakeholders, a “more local” management of the production-consumption constraint, and stochastic aspects with the integration of – local – renewable energy sources with very uncertain generation. In this context, many new problems can be tackled using the tools of game theory [Saad2012]. This course proposes a few of such illustrative examples, linking practical crucial issues of electricity systems operators to wellknown classes of games (routing, potential [Mohsenian-Rad2010, Beaude2016, Jacquot2017], matching [Zeng2016], auctions [Bhattacharya 2014, Horta2017]). This will highlight the vitality of the field of “game-theory applied to Smart Grids”, and potential avenues to improve this link.
