Next generation wireless access networks (5G and beyond) are being designed to support mobile edge cloud services with tight latency constraints.  In this talk, we consider the design challenges of realizing low latency applications such as augmented/virtual reality (AR/VR) and cyber-physical systems, starting with an identification of bottlenecks associated with current technologies.  An end-to-end approach for latency reduction is proposed via improvements to the radio access layer, the mobile core network architecture and the edge cloud subsystem.  Specific techniques for reducing latency are discussed, including redesign of the mobile core network with fast optical technology and elimination of centralized gateways, virtual network protocols with application aware routing, and real-time scheduling and orchestration of cloud tasks.  The talk concludes with a brief overview of the COSMOS testbed currently being deployed in New York City for the purpose of supporting experimental research on emerging edge-cloud enhanced wireless systems. 

Dipankar Raychaudhuri is Distinguished Professor, Electrical & Computer Engineering and Director, WINLAB (Wireless Information Network Lab) at Rutgers University. As WINLAB's Director, he is responsible for an internationally recognized industry-university research center specializing in wireless technology. He has served (or is serving) as principal investigator for several large U.S. National Science Foundation funded projects including the "ORBIT" wireless testbed, the “MobilityFirst” future Internet architecture, and the COSMOS city-scale platform for advanced wireless research.

Dr. Raychaudhuri has previously held corporate R&D positions including: Chief Scientist, Iospan Wireless (2000-01), Assistant General Manager & Department Head, NEC Laboratories (1993-99) and Head, Broadband Communications, Sarnoff Corp (1990-92).  He obtained the B.Tech (Hons) from IIT Kharagpur in 1976 and the M.S. and Ph.D degrees from SUNY, Stony Brook in 1978, 79. He is a Fellow of the IEEE and the recipient of several professional awards including the Rutgers School of Engineering Faculty of the Year Award (2017), IEEE Donald J. Fink Award (2014),  Indian Institute of Technology, Kharagpur, Distinguished Alumni Award (2012), and the Schwarzkopf Prize for Technological Innovation (2008).
