5G Network Architecture and the Future Mobile Internet
Guest Speaker: Dipankar Raychaudhuri, Rutgers University
Host: Sujit Dey, Director, CWC
This special seminar with Rutgers professor Dipankar Raychaudhuri is organized by the Center for Wireless Communications (CWC).
This talk provides a discussion of one of the central design challenges associated with next-generation “5G” wireless systems - that of effectively converging 3GPP-based mobile networks with the global Internet. Although the trend towards “flat” IP-based architectures for cellular networks is well under way with LTE, significant architectural evolution will be needed to achieve the goal of supporting the needs of mobile devices and applications as “first-class” services on the Internet. Several emerging mobility service scenarios including hetnet/small cell, multi-network access, mobile cloud, IoT (Internet-of- Things) and V2V (vehicleto-vehicle) are examined and related network service requirements such as user mobility, disruption tolerance, multi-homing, content/service addressability and context-aware delivery are identified. Drawing from our experience with the ongoing NSF-sponsored “MobilityFirst” future Internet architecture project, we outline a “named-object” protocol solution based on the “GUID (Globally Unique Identifier) Service Layer” which enables a clean separation of naming and addressing, and provides intrinsic support for a wide variety of mobility services. The talk concludes with a brief outline of the MobilityFirst proof-of- concept prototype currently being deployed on the GENI meso-scale networking testbed.
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 is also PI for several large U.S. National Science Foundation funded projects including the "ORBIT" wireless testbed and the “MobilityFirst” future Internet architecture. Dr. Raychaudhuri has previously held corporate R&D positions including: Chief Scientist, Iospan Wireless (2000-01), AGM & Dept 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.
