Femtocells and Games: Towards self-organizing small-cell networks
Walid Saad, University of Miami, USA


The deployment of small cells serviced by low-cost, low-power femtocell access point is envisioned to significantly improve the performance of next-generation wireless networks. The key to a successful deployment of femtocells lies in the design of novel algorithms and techniques that ensure an efficient co-existence between the femtocell tier and the existing macro-cell wireless infrastructure. In this talk, we study the potential of applying game-theoretic techniques for addressing various challenges in femtocell networks such as interference management and self-organization. In particular, we focus on three important problems:
(i) Noncooperative games for strategic access policies,(ii)- Cooperative games for spectrum leasing and interference management, and (iii)- Matching games for user-to-access point association. For each problem, we present the key concepts, discuss the proposed solutions, and shed a light on future opportunities.


Walid Saad received his B.E. degree in Computer and Communications Engineering from the Lebanese University, Faculty of Engineering, in 2004, his M.E. in Computer and Communications Engineering from the American University of Beirut (AUB) in 2007, and his Ph.D degree from the University of Oslo in 2010.  From August 2008 till July 2009 he was a visiting scholar in the Coordinated Science Laboratory at the University of Illinois at Urbana Champaign.  From January 2011 till July 2011, he was a Postdoctoral Research Associate at the Electrical and Computer Engineering Department at Princeton University.

Currently, he is an Assistant Professor at the Electrical and Computer Engineering Department at the University of Miami. His research interests include applications of game theory in wireless networks, small cell networks, cognitive radio, wireless communication systems (UMTS, WiMAX, LTE, etc), and smart grids. He was the first author of the papers that received the Best Paper Award at the 7th International Symposium on Modeling and Optimization in Mobile, Ad Hoc and Wireless Networks (WiOpt), in June 2009 and  at the 5th International Conference on Internet Monitoring and Protection (ICIMP) in May 2010.

There is much energy within the community to develop more advanced BWA technologies - activities span the wireless domain, ranging from more advanced antenna technologies to cooperative relays to mesh networking systems and many more: future networks will likely employ some mix of thdifferent mechanisms. We anticipate that this 4th workshop will continue the series of successful workshops, providing a forum for new research results and reports on practical experience working with innovative technologies in the domain of Broadband Wireless Access. The workshop, then, is soliciting contributions including but not limited to topics listed belo
