Title: Modeling and Analysis of Next-Generation Cellular Networks Using
Stochastic Geometry


Cellular networks are becoming increasingly irregular and heterogeneous, and advanced communication and interference mitigation techniques make the notion of a conventional cell obsolete, where there exists a hard association of a user to a single base station. In view of these developments, new modeling and analysis techniques are needed that permit general statements on the network performance and provide answers to fundamental questions on how to engineer future cellular systems. Stochastic geometry provides both the models and the mathematical tools for their analysis, often resulting in closed-form expressions for the distribution of fundamental quantities such as the signal-to-interference ratios (SIRs) and coverage probabilities. Starting from a basic Poisson model, we will present different refinements of models for heterogeneous cellular systems, and we will derive the SIR distribution and analyze different forms of base station cooperation. It turns out that the mean interference-to-signal ratio plays a crucial role in determining the SIRs for different architectures and transmission schemes.


Martin Haenggi is a Professor of Electrical Engineering and a Concurrent Professor of Applied and Computational Mathematics and Statistics at the University of Notre Dame, Indiana, USA. Currently he is also an Invited Professor at the Swiss Federal Institute ofTechnology in Lausanne (EPFL). He received the Dipl.Ing. (M.Sc.) and Dr.sc.techn. (Ph.D.) degrees in electrical engineering from the Swiss Federal Institute of Technology in Zurich (ETH) in 1995 and 1999, respectively. He served on the Editorial Boards of the Journal of Ad Hoc Networks, the IEEE Transactions on Mobile Computing, the IEEE Journal on Selected Areas in Communications, the IEEE Trans. on Vehicular Technology,and the ACM Trans. on Sensor Networks. Currently he is the chair of the Executive Editorial Committee of the IEEE Trans. on Wireless Communications. He was a Distinguished Lecturer for the IEEE Circuits and Systems Society in 2005-06, and he authored the monograph "Interference in Large Wireless Networks" (NOW Publishers, 2008) and the textbook "Stochastic Geometry for Wireless Networks" (Cambridge, 2012), and more than 200 articles in international journals and conferences.  He is a Fellow of the IEEE, and he received the ETH Medal for both his M.Sc. and Ph.D. theses, a CAREER award from the U.S. National Science Foundation in 2005, and the 2010 IEEE Communications Society Best Tutorial Paper award.
