Invited Talk 1: ”Open Source oneM2M Platforms”
Mr. Jaeho Kim, Director, KETI
Abstract:
The Internet of Things (IoT) is gaining ground in various vertical domains such as healthcare, home automation and public services. Since IoT connects all smart objects and enables them to communicate with each other, the intelligent services introduced by IoT will provide a huge impact on our everyday life. However, this requires a common and open platform satisfying all different needs from various stakeholders and verticals. In order for such a common service platform to be useful, an international standard is required to support interoperability. This talk, therefore, will provide the effort of oneM2M standardization activities for IoT/M2M common service platforms. Finally, this talk will introduce an open source IoT service platform, which is called Mobius, implementing oneM2M standards and establishing a global IoT ecosystem with the global use of IoT/M2M devices and software.

Dr. Bekay (Byung Keun) Lim, Vice President, InterDigital Asia
Abstract:
Internet of things (IoT) has been known as one of the inevitable business solutions of the next generation communication services. And we know that there are a lot of technologies, standards, and products providing the IoT services from the chips to servers, from personal scale services to enterprise scale services regardless of the past story. On the other hand, many of the key experts in the market players are skeptical about the IoT business, since there are no concrete and visible solutions making money and backup of the investment of the IoT business yet. Similarly, we are continuously being concerned about the future of the IoT business even though we believe that the IoT will be the key services of the next generation communication networks. Considering the concerns, this talk investigates and analyzes the barriers and enablers of the IoT business in terms of the services, regulations and products through the ecosystems of the IoT business. This talk also introduces how to define and analyze the possibility of success of the IoT services among a myriad of services. Lastly, we suggest several key enablers making the IoT business become the money making business against current technologies, regulations, and market situations.

Invited Talk 6: ”Optical Camera Communication based D2D Services”
Dr. Yu Zeng, Research Manager, Beijing Research Institute, China Telecom
Abstract:
China Telecom operates the world's largest fixed network, CDMA2000 mobile network and broadband networks, gained strong technical strength on mobile communications, network gateways, and IPv6 technologies. China Telecom started the visible light communication (VLC) research in 2013, and actively participated in industry, domestic and international standard organizations including the IEEE 802.15.7. China Telecom is one of the first operators to get involved in VLC standards, continue to contribute to VLC-related IEEE 802 standards and promote viable VLC techniques. For mobile devices, projects “e-trans” and “dynamic QR code” paved the way for possible VLC applications. Demonstrations were developed using different screen coding. The link can achieve transfer data rate up to 80Mb/s. This will provide possible solutions for VLC systems. For industrial applications, large shopping malls, banks and stations can take advantages of LED lighting bulbs, and be treated as small "hot spots", deliver capabilities such as advertising and promotion vouchers, membership information, store APP client and even indoor navigation. VLC can also bring more possibilities to public transport service companies. VLC systems are economical, convenient, interference free and can be easily applied within the constrained space. For the tourism industry, using VLC technology enables better information delivery when other connection methods are limited, and can also provide statistical analysis through mobile applications. The VLC technology is one of the future trends for short range communications. The industry can take advantages from the knowledge and experience provided by telecom operators.

Invited Talk 7: “Spectrum Management based on Spectrum Database for the 5G and beyond Wireless World”
Dr. Takeo Fujii, Professor, Advanced Wireless and Communication Research Center, The University of Electro-Communications, Japan
Abstract:
The spectrum management is a key issue for sustainable growth of future wireless communication systems. Due to the rapidly increasing number of wireless devices, not only smart phones but also terminals for IoT, the scarcity of the spectrum suitable for mobile communications becomes a serious problem in the 5G and beyond wireless world. Currently, each spectrum band is allocated to an individual system without any spectrum sharing in the same area except for the very limited spectrum, e.g., the spectrum for the wireless LAN. However, this kind of monopolized spectrum allocation policy degrades the spectrum efficiency because lots of unused spectrum remained in the temporal domain and the spatial domain. In future wireless communication systems, we need to consider dynamic sharing of the spectrum among multiple systems for realizing the highly efficient spectrum utilization. In 5G mobile communications, it is required to consider spectrum sharing such as authorized shared access (ASA), unsilenced LTE (U-LTE), TV white space, and public safety. Moreover, dynamic autonomous spectrum management shifted from the fixed spectrum allocation is an important issue for creating a new wireless world. In this presentation, to effectively manage the limited resource of spectrum, we show the concept of hierarchical spectrum database where a hierarchical structure is considered. A lower layer database collects information about the local radio and network environment like measured received power, connectivity of terminals, type of data packets and so on by user terminals, and the information is statistically stored. By using the information, the spectrum and network environment can be known. This kind of information is transferred and summarized at the higher layer and dynamical spectrum management considering the demands of users and also spectrum efficiency can be achieved. Therefore, more flexible and dynamic spectrum allocation can be realized. At the highest layer, a global spectrum allocation policy can be defined for deciding the basic spectrum utilization policy managed by regulators. A spectrum management of the hierarchical spectrum database is based on big data of radio and network environment collected by a huge amount of user terminals. The spectrum database can help the channel management of not only the current spectrum shared bands like 2.4GHz and 5GHz but also the new spectrum shared bands based on ASA and other future spectrum sharing system with new technologies.

Invited Talk 10: “System Architectures, Mathematical Modeling, and Algorithms for Holographic Three-Dimensional Displays”
Dr. Hwi Kim, Professor, Dept. of Electronics and Information Engineering, Korea University
Abstract:
Holographic three-dimensional (3D) display technology is considered as the ultimate form of realistic three-dimensional displays. However, the development status is at the very initial stage, so it is expected that the practical realization of high quality holographic 3D displays will not be seen in the near future. There are still several fundamental issues in almost all aspects of holographic 3D displays, which have to be resolved with a ground-breaking research. In this presentation, the system architectures that have been researched in our country are reviewed, and a research on mathematical modeling and simulation techniques for those holographic 3D displays is introduced. The holographic content generation is a key technology in this field. Broadly speaking, holographic 3D display is considered as one of computational displays because the content generation is carried out by non-intuitive complicated numerical algorithms. The design concepts of computational algorithms and concrete case studies of computer-generated holograms (CGHs) are presented. A fundamental study on the wave optic understanding of human eyes and perception of three-dimensional scene and theoretical analysis on the information capacity of holograms in terms of space-bandwidth-product (SBP) are also discussed. In order to display CGHs contents with the real light field, we have developed several holographic display architectures. Underlying design concepts, characteristic features, and limitations of several system architectures are briefly introduced. Perspectives on system architecture and algorithms of CGHs will also be addressed.

Invited Talk 11: “Holography-like High Density Multiview 3D Display for Realistic Visual Effect”
Dr. Sung Kyu Kim, Principal Research Scientist, Imaging Media Center, Korea Institute of Science and Technology
Abstract:
Autostereoscopic 3D display technology which removes the need for special eye glasses for 3D image and multiview 3D is being developed for commercialization nowadays. Integral Photography (IP) and Super Multi-View (SMV) will be the next generation of multiview type 3D display, and holographic 3D display is considered as the final goal technology of 3D display. There have been many attempts for the mass product commercialization of multiview 3D technology. Parallax barrier and lenticular types are the usual approaches, while the light field 3D technology has emerged as a new kind of multiview 3D display. Multiview 3D display has several problems that hinder popular utilization such as low quality and high crosstalk of 3D image, narrow viewing area caused by the limited number of viewpoints, low resolution of each viewpoint image, and eye fatigue phenomenon. Some of these problems can be solved by using real-time face or eye tracking technology, when 3D display for a single viewer is considered. However multi-user viewing and eye fatigue are still important problems. SMV 3D technology is developed to overcome those problems and High Density Multiview (HDM) 3D technology resembles characteristics of the light field and SMV types. In this talk, we introduce recent developments in HDM 3D displays.

Invited Talk 12: “Core Technologies and Challenges in Augmented Reality and Virtual Reality”
Dr. Jong-Il Park, Professor, Dept. of Computer Science and Engineering, Hanyang University
Abstract:
Augmented Reality (AR) and Virtual Reality (VR) are emerging fast as a practical way of enriching our everyday lives. AR is a live view of a real-world environment where some of the useful information is carefully augmented by a computer. In contrast, VR replaces the real world with a simulated world as if the user is immersed in the virtual world. In this talk, the concept of AR/VR is explained and recent trends are overviewed first. Then, the core technologies for realizing the AR/VR are introduced. Critical enabling technology of AR/VR has been camera tracking for long time. Owing to the rapid progress in computer vision technology, camera tracking is getting matured in many ordinary situations. Object recognition and tracking are also key technologies for intelligent services. Moreover, seamless compositing of real and virtual worlds is very important as presence and immersion are essential in AR/VR. Through this presentation, important technical issues in core technologies are illuminated. Finally, the future of our life is discussed in relation to AR/VR.

Invited Talk 13: “Joint Mobile Power Management for OS, Network, and Service“
Dr. Young-June Choi, Professor, Dept. of Computer Engineering, Ajou University
Abstract:
Mobile systems are very sensitive to the drainage of battery energy as the performance of mobile application processors is evolving dramatically. Due to the battery constraint, mobile systems deploy many solutions such as dynamic voltage and frequency scaling (DVFS) and multi-core technologies. Also, network connectivity drives mobile devices to waste much energy regardless of user activities. To resolve this, LTE networks use an energy efficiency solution such as connection management and discontinuous reception (DRX). In this talk, we discuss joint solutions that consider energy efficiency of three domains: OS, network, and service.

Invited Talk 14: “Cellular Terminal Modem Development Trends and Future Prospects”
Dr. Chaehag Steve Yi, Master (VP), Samsung Electronics
Abstract:
An easy and active sharing of information is a main success factor of a data-driven world, where all individuals have become active participants. In the data-driven world, mobile devices such as smart-phones, tablets, and wearables have become indispensable to users for their everyday life. Major enablers of this data-driven world are advances in cellular and connectivity technologies which support wireless capacity enough to accommodate data traffic surge. Cellular mobile communications systems have been evolving, is evolving, and will evolve continuously. All cellular systems have been unified into the LTE system which introduces new features without pause such as D2D (Device-to-Device), LAA (Licensed Assisted Access), and FD-MIMO (Full Dimension-MIMO). Therefore, in the development of cellular terminal modem chipsets, one of the most important things is to implement new features on time and to respond to the market requirements. In other sides, to prepare mid/low end markets which become dominant markets, various types of integration of major components of smart-phone, such as application processor, baseband modem, RF device, power management, and wireless connectivity, have been attempted to make cost reduction. Furthermore, it becomes more important to provide hardware and software turn-key solutions.

Invited Talk 15: “Wi-Fi Offloading: Mobile CDN’s Perspective”
Dr. Yung Yi, Professor. Dept. of Electrical Engineering, KAIST
Abstract:
This talk presents our recent research on Wi-Fi offloading. Wi-Fi offloading has been typically applied as a way of augmenting cellular networks’ capacity, but our research proposes a new angle taken from the mobile CDN system’s perspective. Exploiting people’s diverse mobility and traffic diversity that often allows delay tolerant delivery, time can be used as an important resource of reliably and cheaply delivering mobile contents. We have built a Wi-Fi offloading based mobile CDN system as well as an example application, and this talk summarizes the major challenges in doing so and how we solve them. Through this system development, we also discuss how to build up a good mobile ecosystem where users, content providers, and mobile network operators are all happy in the future.

Invited Talk 16: “Enabling Real-time Centralized Optimization for Global-Scale Video Delivery”
Dr. Dongsu Han, Professor, Dept. of Electrical Engineering, KAIST
Abstract:
Live video delivery is a rapidly growing business and its traffic is expected to reach a peak of 50 Tbps this year. Popularization of personal broadcasting and streaming mega-events are leading the trend. This surging popularity, however, can potentially challenge how Internet video delivery is done. Traditional video delivery networks (e.g., content delivery networks) are facing challenges because they must meet users’ demands for fast join times, high bitrates, and low buffering ratios, while minimizing their own cost of delivery and responding to issues in real-time. Wide-area latency, loss, and failures, as well as varied workloads (“mega-events” to long-tail), make meeting these demands more challenging. A recent analysis of video sessions suggested that a centralized controller could improve user experience by controlling the resource globally. However, enabling the centralized control raises many design and implementation issues due to the difficulty of quickly handling failures, a requirement of both operators and users. In this talk, we explore how we might enable the centralized control over a globally distributed network with real-time requirements. Our key approach is to utilize both centralized and decentralized control, while minimizing negative interactions between the two. To provide a concrete example, we present VDN, a practical approach to a video delivery network that uses a centralized algorithm for live video optimization. VDN provides CDN operators with real-time, fine-grained control. Despite of challenges resulting from the wide-area (e.g., state inconsistency, partitions, failures), we show that using a hybrid control plane increases video quality and decreases the delivery cost. This work is a joint work between KAIST and Carnegie Mellon University.
