Multi-RAT Bandwidth Aggregation Mechanism and its Implementation with SDN

Abstract:

Smart mobile devices have become popular in the recent years, which drive the mobile traffic growth rapidly. To deal with the traffic explosion, heterogeneous radio network integration is considered as a cost-effective solution for mobile operators to reduce network congestion. Most existing smart mobile devices are equipped with multiple radio interfaces, including Long Term Evolution (LTE), Wi-Fi, Wideband Code Division Multiple Access (WCDMA), and so on. Therefore, multiple radio access technology (multi-RAT) is a viable solution that combines, for example, Wi-Fi and cellular technology to fulfill the explosive growth of user data traffic. Many mobile operators have deployed Wi-Fi hotspots integrated with mobile networks. Such bandwidth aggregation is a solution that enhances the performance of high-bandwidth applications by aggregating the offered bandwidth from multiple RATs. This talk considers bandwidth aggregation based on service flows, that is, different network interfaces are used to transmit different service flows (e.g., use LTE to transmit VoIP service and Wi-Fi to transmit File Transfer Protocol; FTP service). Hence, we can utilize the network capabilities properly (e.g., the LTE network can guarantee the transmission bit rate and is suitable for transmitting VoIP service). Furthermore, we extend the concept of bandwidth aggregation on multi-RAT to an emerging proposed network architecture called software-defined networking (SDN). In our approach, the SDN controller is installed an Aggregation Control Bundle (ACB) for handling multi-RAT bandwidth aggregation. We show good performance with this architecture.

Title of Presentation:

Socially Enabled Wireless Networks

Abstract:

Emerging online social networks significantly change the way of content distribution and information dissemination, while the traffic of social networks dominates Internet traffic in the communication networks. Therefore, it is vital to design future wireless networks and 5G mobile communications by properly leveraging the properties of social networks. In 2003, Chen, Chiang, and Poor suggested the importance of understanding the interplay between social network and technological networks. We shall further look into the fundamentals of network science and subsequent social network analysis, and the abstract ways to utilize the nature of social networks to design wireless networks, supplying with successful engineering examples. It shall open a new scenario in the technology development of wireless networks and wireless communications.

Biography

Kwang-Cheng Chen received the B.S. from the National Taiwan University in 1983, and the M.S. and Ph.D from the University of Maryland, College Park, United States, in 1987 and 1989, all in electrical engineering. From 1987 to 1998, Dr. Chen worked with SSE, COMSAT, IBM Thomas J. Watson Research Center, and National Tsing Hua University, in mobile communications and networks. Since 1998, Dr. Chen has been with National Taiwan University, Taipei, Taiwan, ROC, and is the Distinguished Professor in the College of Electrical Engineering and Computer Science, National Taiwan University. He is visiting the Research Lab. of Electronics at the Massachusetts Institute of Technology, 2015-2016. Dr. Chen was with the STAG, Executive Yuan, to engineering Taiwan’s telecommunication deregulation and to plan nation’s regulator (today’s NCC) in 1990’s. He founded INPROCOMM Inc. in 2001, which was acquired by MediaTek Inc. in 2004. He has been actively involving in the organization of various IEEE conferences as General/TPC chair/co-chair, serving editorships with a few IEEE journals, and various IEEE volunteer services with IEEE Fellow Committee, IEEE VTS Fellow Evaluation Committee, Asia Pacific Board, etc. Most recently, he founds and chairs the Technical Committee on Social Networks in the IEEE Communications Society. Dr. Chen also has contributed essential technology to various international standards like IEEE 802 wireless LANs, Bluetooth, LTE (4G wireless communications) and LTE-A. He has authored and co-authored 250 IEEE papers and more than 20 granted US patents. He co-edited (with R. DeMarca) the book Mobile WiMAX published by Wiley in 2008, and authored the book Principles of Communications published by River in 2009, and co-authored (with R. Prasad) another book Cognitive Radio Networks published by Wiley in 2009. Dr. Chen is an IEEE Fellow and has received a number of awards including very recent 2011 IEEE COMSOC Wireless Communication Recognition Award, 2014 IEEE Jack Neubauer Memorial Award, 2014 IEEE COMSOC AP Outstanding Paper Award. Dr. Chen’s current research interests include wireless communications, network science, and data analytics.
