Wireless communication has grown by leaps and bounds in recent decades, with huge social and societal impact. This is nowhere near saturation, especially with the ongoing emergence of the Internet of Things. Underlying this technology are fundamental questions: what is the capacity of wireless networks, what are methods to achieve it, how to efficiently configure and adapt communication links, organize access to the medium, overcome interference, and disseminate information.
Different schools of thought have arisen to tackle these fundamental questions. These come from different backgrounds, involving different types of mathematical and practical tools and different approaches and outlooks. The goals of this Dagstuhl Seminar are twofold: first, to bring together top researchers from these different research communities to review and discuss models and methods in order to obtain a better understanding of the capabilities and limitations of modern wireless networks. Second, to formulate more realistic models, new algorithm and protocol design approaches, and new system ideas for future wireless networks that may be subsequently investigated in joint research projects.
One source of bifurcation within the various theory camps is whether to model the environment as a stochastic process with known or unknown parameters (typical in the EE information theory and network control/optimization theory communities) or as a worst-case adversary (typical in the CS theory community). These perspectives sometimes yield very similar algorithms but different guarantees.
Another challenging topic where multiple viewpoints are evident is the lack of constancy, or the frequent changes in reception conditions. One particular type of time-varying interference is due to other networks, typically under separate control. These changes and interferences can be treated or modeled in different ways. In particular, they can be viewed either as stochastic, oblivious, or adversarial. This is an area that could particularly benefit from cross-discipline discussions.
A completely different way of dealing with interference is to co-opt it. Sophisticated schemes have been developed to exploit interference from simultaneously transmitting relays to significantly increase throughput and reliability, including interference alignment, quantize-map-forward relaying, distributed MIMO, beamforming and interference cancellation. All these techniques call for very different approaches to fundamental dissemination problems. The practical implementability in the context of large-scale distributed systems of many of these schemes is still unclear. We hope that the conversations in this seminar will drive collaborations around new kinds of practical measurements and experiments (e.g., new implementations of physical- and link-layer approaches).
An important part of the seminar is to actively promote a dialog between different communities. As a result, we seek researchers that are by nature open to different perspectives and have enough self-confidence to welcome research of a different nature. The objective is for each participant to consciously reflect on and articulate the implicit values, identity, shared understandings and skill set that people in his/her community expect.
