講師:黃崇明 特聘教授
Chung-Ming Huang received the B.S. degree in electrical engineering from National Taiwan University on 1984/6, and the M.S. and Ph.D. degrees in computer and information science from The Ohio State University on 1988/12 and 1991/6 respectively. He is currently a Distinguished Professor of Dept. of Computer Science and Information Engineering, National Cheng Kung University, Tainan, Taiwan, R.O.C. He (i) was Chair of Dept. of Computer Science and Information Engineering and Director of Institute of Medical Informatics, National Cheng Kung University, Taiwan, R.O.C. and (ii) served as the Chair of IEEE Vehicular Technology Society Tainan Chapter. He has published more than 300 referred journal and conference papers in wireless and mobile communication protocols, interactive multimedia systems, audio and video streaming and formal modeling of communication protocols. His research interests include wireless and mobile network protocol design and analysis, green computing and communication, media processing and streaming, and innovative network applications and services. He a senior member of IEEE (SM’07) and ACM (SM’12).
Data offloading plays an important role for the mobile data explosion problem that occurs in cellular networks. In the past, data offloading was considered in the mobile-to-infrastructure scenario, e.g., regular smart phone’s data offloading from 4G cellular network to Wi Fi network and VANET’s V2I data offloading. In the next generation of wireless mobile network, i.e., 5G and Beyond 5G (B5G), V2V communication would use cellular network to communicate with each using cellular network. Thus, how to have data offloading from cellular network to IEEE 802.11p vehicular ad hoc network for V2V communication needs to be considered and resolved. In this talk, an idea and control scheme for offloading vehicular communication traffic from the cellular network to V2V paths that can exist in IEEE 802.11p vehicular ad hoc networks (VANETs) are presented. A software defined network (SDN) inside the mobile edge computing (MEC) architecture, which is abbreviated as the SDNi-MEC server, is devised to tackle the complicated issues of VANET V2V offloading. Using the proposed SDNi-MEC architecture, each vehicle reports its contextual information to the context database of the SDNi-MEC server, and the SDN controller of the SDNi-MEC server calculates whether there is a V2V path between the two vehicles that are currently communicating with each other through the cellular network. This proposed method (1) uses each vehicle’s context, (2) adopts a centralized management strategy for calculation and notification, and (3) tries to establish a VANET routing path for paired vehicles that are currently communicating with each other using a cellular network. The performance analysis for the proposed offloading control scheme based on the SDNi-MEC server architecture shows that it has better throughput in both the cellular networking link and the V2V ad hoc paths when the vehicle’s density is in the middle.

講師:蔡欣穆 副教授
Hsin-Mu (Michael) Tsai is Jen-Min Young Scholar Chair (Associate) Professor in Department of Computer Science and Information Engineering at National Taiwan University, Taipei, Taiwan. He received his B.S.E in Computer Science and Information Engineering from National Taiwan University and his M.S. and Ph.D. in Electrical and Computer Engineering from Carnegie Mellon University. He spent a year in General Motors Research and Development as an intern researcher during his Ph.D. study. From 2013 to 2015, Dr. Tsai co-led the intelligent transportation system group in the Intel-NTU Connected Context Computing Center, a research center jointly established by Intel, National Taiwan University, and National Science Council, Taiwan, to address research challenges in Internet of Things.
Dr. Tsai's recognitions include 2015 ACM Taipei Chapter’s K. T. Li Young Researcher Award, 2014 Intel Labs Distinguished Collaborative Research Award, 2013 Intel Early Career Faculty Award (the first to receive this honor outside of North America and Europe), and 2013 National Taiwan University's Distinguished Teaching Award (awarded to top 1% teaching faculty at the university). He serves as General co-chair for IEEE Vehicular Networking Conference (VNC) 2018, and has served as TPC co-chairs for ACM CarSys 2017, IEEE VNC 2016, ACM VANET 2013, and as a founding co-chair for ACM Visible Light Communication System (VLCS) Workshop in 2014. His research interests include vehicular networking and communications, intelligent transportation systems, visible light communications, and wireless channel and link measurements.  
Connecting vehicles with wireless communications creates new opportunities to enable a new spectrum of vehicular applications, as well as to significantly improve the performance of transportation, for example, in terms of road capacity and energy efficiency. However, vehicle-to-vehicle communications required for such cooperative systems also poses new technical and non-technical challenges, which is not yet completely addressed by existing radio frequency (RF) based solutions. In this talk, I will present Vehicular Visible Light Communications (V2LC). Utilizing optical signals to carry information, V2LC uses automotive LED lights as the transmitter and a camera or a photodiode module as the receiver. I will also give a number of examples of automotive applications that can be supported by V2LC. Finally, I will also elaborate on why V2LC is an attractive solution that can address the challenges faced by vehicular communications.
