Emeritus Professor Zygmunt J. Haas recently delivered a talk at the KTH Royal Institute of Technology in Stockholm, Sweden as part of the ACCESS Distinguished Lecture Series. The invited lecture, “Reconfigurable Distributed MIMO for Physical-layer Security in Mobile Networks,” was presented on September 13, 2018.
In his talk, Haas discussed the model and performance of the distributed MIMO architecture for mobile networks, which is referred to as Reconfigurable Distributed MIMO (RD-MIMO). In RD-MIMO, the communicating mobile nodes temporarily recruit adjacent nodes to operate as distributed antenna arrays. To best serve the communicating nodes, the node clusters are continuously reconfigured due to the node mobility and the varying channel conditions. The frequency of reconfiguration depends on the required system performance, exhibiting a tradeoff between performance and complexity. Owing to the diversity and differring-in-time channel conditions, Haas postulated that the RD-MIMO architecture may be especially well suited to physical-layer security in future systems, such as in Vehicular Networks and in Internet of Things. This work has been funded by ARL grant number W911NF-18-1-0406.
ACCESS Distinguished Lecture Series brings eminent speakers from prestigious universities to KTH from around the world. As part of ACCESS mission to interface with society many of these lectures extend to broader popular areas of interest, such as the sub-prime crisis, the roles that popularity and novelty play in eliciting attention in the Web or systems for intelligent buildings and environmental monitoring.
Haas received the Ph.D. degree in electrical engineering from Stanford University, Stanford, CA, USA, in 1988. In 1988, he joined AT&T Bell Laboratories in the Network Research Area, where he pursued research in wireless communications, mobility management, fast protocols, optical networks, and optical switching. In August 1995, he joined the faculty of the School of Electrical and Computer Engineering, Cornell University, Ithaca, NY, USA, where he is currently a Professor Emeritus. As of October 2013, he is also a Distinguished Chair in Computer Science at the University of Texas at Dallas. He is a Fellow of the IEEE.
Dr. Haas heads the Wireless Network Laboratory (WNL), a research group with extensive contributions and international recognition, focusing on the area of wireless ad hoc networks and sensor networks. He has authored over 200 technical conference and journal papers and holds 20 patents in the areas of wireless networks and wireless communications, optical switching and optical networks, and high-speed networking protocols. His research interests include protocols for mobile and wireless communication and networks, secure communications, and modeling and performance evaluation of large and complex systems.
