EE / YINS Seminar: Cross-Layering in Future Wireless Networks: From Compact Full-duplex Radios to City-Scale Experimentation with Tingjun Chen (Columbia/Yale)


Future wireless networks will feature the technology “sweet spot” of high bandwidth, low latency, and powerful edge computing, thereby enabling a broad new class of applications such as augmented reality, autonomous vehicles, and smart cities. Realizing this vision requires theoretical and experimental research efforts focusing on emerging communication technologies (e.g., full-duplex wireless, beamforming, millimeter-wave, and fiber-optics) and their interactions with the higher layers in the network stack.

ACM SIGMETRICS selected Dr. Leandros Tassiulas of Yale University (and the Yasle Institute for Network Science) as the recipient of the 2020 ACM SIGMETRICS Achievement Award in recognition of his influential contributions to the foundations of network control and optimization with applications in computer and communication networks.  

Dr. Tassiulas is John C Malone Professor of Electrical Engineering at Yale University and member of the Yale Institute for Network Science since 2014. He received a Diploma in Electrical Engineering from the Aristotelian University of Thessaloniki in 1987 and a PhD in Electrical Engineering from the University of Maryland in 1991. He held faculty positions at the Polytechnic University of New York, University of Maryland and University of Thessaly, Greece.  

His research interests are in the field of computer and communication networks with emphasis on fundamental mathematical models and algorithms of complex networks, architectures and protocols of wireless systems, sensor networks, novel internet architectures, network economics and experimental platforms for network research. He pioneered the use of Lyapunov stability analysis for network control design and optimization. Based on this approach he proposed the max-weight scheduling algorithm and the back-pressure network control policy, as well as opportunistic scheduling in wireless. These advances influenced the design of internet switches, cross-layer architectures in wireless networks, resource allocation in cloud computing and more recently logistics and modern approaches to vehicular transport networks. Other notable contributions include the maximum lifetime approach for wireless network energy management, and the consideration of joint access control and antenna transmission management in multiple antenna wireless systems. He co-authored the book Resource allocation and cross-layer control in wireless networks (Now publishers 2006).  

Dr. Tassiulas has received numerous honors for his work over the years including the IEEE Kobayashi Award for Computer Communication (2016), the IEEE INFOCOM achievement award (2007) and several best paper awards.

“Solving the Blockchain Trilemma”

Speaker: David Tse, Thomas Kailath and Guanghan Xu Professor of Electrical Engineering, Stanford University

Description: The blockchain trilemma is a conjecture which states that it is impossible to build a fully decentralized blockchain system whose security and transaction throughput both scale linearly with the number of nodes in the network. We provide a resolution to the conjecture.
