WiOpt main symposium
Abstract: Multi-hop wireless networks are wireless systems in which wireless nodes are capable of relaying other nodes' transmissions. The ability to relay can significantly improve network performance over single hop transmissions. Further, these networks can often be implemented with minimal infrastructure needs and find a myriad of applications that have been extensively studied (e.g., mesh, sensor, MANET systems). While multi-hopping improves performance, it also significantly complicates network design, and traditional ad hoc approaches often result in poor overall performance. Thus, there is a pressing need to develop an analytical foundation that is mathematically rigorous, conceptually unifying, and leads to the development of low-complexity and practically-implementable resource allocation algorithms. In this talk, I will briefly overview some of the recent breakthroughs that have taken place in the development of such an analytical framework noting that a rigorous approach to design that accounts for complexity and scalability can lead to substantial performance gains over traditional approaches used in the state-of-the-art design of wireless systems. While substantial strides have been made in achieving "first order metrics of performance" such as throughput and stability, many interesting and practically critical problems are still open. In the course of this talk I will describe some of these critical open problems, the various challenges that they pose, and some preliminary work approaches to resolve them.

His research interests span the areas of wireless and wireline communication networks. He is especially interested in fundamental problems in the design, control, performance, pricing, and security of these networks. Dr. Shroff is a past editor for IEEE/ACM Trans. on Networking and the IEEE Communication Letters. He currently serves on the editorial board of the Computer Networks Journal. He has chaired various conferences and workshops and co-organized workshops for NSF to chart the future of communication networks. Dr. Shroff is a Fellow of the IEEE and an NSF CAREER awardee. He has received numerous best paper awards for his research, e.g., at IEEE INFOCOM 2008, IEEE INFOCOM 2006, IEEE IWQoS 2006, Journal of Communication and Networking 2005, Computer Networks 2003, and one of two runner-up papers at IEEE INFOCOM 2005.
Abstract: The emergence of programmable wireless platforms is opening the door for experimental research with wireless designs that were previously only considered in theoretical and simulation studies. In this talk, I will describe emerging wireless implementations and the experimental and theoretical research questions they pose. I will address multiple applications including WLANs, urban access networks, and vehicular networks.
Bio: Edward Knightly is a Professor of Electrical and Computer Engineering at Rice University in Houston, Texas. He received his Ph.D. and M.S. from the University of California at Berkeley and his B.S. from Auburn University. He is an IEEE Fellow, a Sloan Fellow, and a recipient of the National Science Foundation CAREER Award. He received the best paper award from ACM MobiCom 2008. Professor Knightly's research interests are in the areas of mobile and wireless networks and high-performance and denial-of-service resilient protocol design. He leads the Rice Networks Group. The group's current projects include deployment, operation, and management of a large-scale urban multi-hop multi-tier IEEE 802.11 network in a Houston under-resourced community. This network, TFA Wireless, is serving over 4,000 users in several square kilometers and employs custom-built programmable and observable access points. The group is also developing a clean-slate-design hardware platform for high-performance multi-hop wireless. The TAPs/WARP platform is now operational, and ongoing research includes cross-layer protocol design and implementation.
Abstract: The talk will discuss U.S wireless industry trends and opportunities in optimizing management of growing multi-generational networks (2G, 3G and 4G/LTE) that support diverse services and devices including M2M, smart phones, e-readers, data cards etc. Control plane and user plane traffic engineering required will be discussed along with cross-layer optimization for performance. Finally, approaches in scaling network instrumentation and performance management to enable economic and effective network operations will be presented.
