Title: Green Cellular Communications: What Are the Potential Gains and How to Achieve Them?

10:00-12:00, Monday, Feb. 16, 2015


Conventional cellular wireless networks were designed with the purpose of providing high throughput for the user and high capacity for the service provider, without any provisions of energy efficiency. As a result, these networks have an enormous Carbon footprint. For example, only in the United States, the Carbon footprint of the cellular wireless industry is equal to that of about 3/4 million cars. In addition, the cellular network is highly inefficient and therefore a large part of the energy dissipated is wasted.

In this lecture, we first analyze the energy dissipation in cellular wireless networks and point to sources of major inefficiency. We also discuss how much more mobile traffic is expected to increase so that this Carbon footprint will increase tremendously more. We then discuss potential sources of improvement at the physical layer as well as at higher layers of the communication protocol hierarchy. For the physical layer, we discuss new modulation formats and new device technologies and what they may bring in terms of energy efficiency gain. At higher layers, considering that most of the energy inefficiency in cellular wireless networks is at the base stations, we discuss multi-tier networks and point to the potential of exploiting mobility patterns in order to use base station energy judiciously. We discuss link adaptation and point to why energy efficiency, and not power efficiency should be pursued and what it means for the choice of link rates. We show how much gain is possible by energy-efficient link rate adaptation. We describe the gains due to the exploitation of nonuniform traffic in space, relays and cooperation, device-to-device communications, multiple antenna technques, and in particular coordinated multipoint and massive MIMO, sleeping modes for the base stations, the techniques of cell breathing and cell zooming, the energy trap problem for the mobile terminals, and the potential approaches for video that provide energy efficiency. We also review several survey papers and books published on this topic.

By a consideration of the combination of all potential gains, we conclude that an improvement in energy consumption in cellular wireless networks by orders of magnitude is possible. The lecture will present in detail where to concentrate research to achieve the largest gains.

Title: Wireless 5G: Challenges from Technical & Services Aspects  (PPT)

16:00-18:00, Monday, Feb. 16, 2015


Right after iPhone was released on June 29, 2007, Steve Jobs’ Un-equilibrium Relationship occurs immediately (i.e. Create a fascinating market gap of a “Demands >> Supply” scenario for consumers), and then affect the “Quality of Services” seriously for many wireless operators ultimately. Now the number of wireless subscribers who use smart phones for video streaming applications and high-speed wireless data usage keeps increasing every day. It has been estimated that the traffic volumes will be increased by at least 10X ~ 1000X from 2010 to 2020. The requirement for energy consumptions will also be sharply increased accordingly. Although more and more wireless operators are now starting to deploy the wireless 4G-LTE systems around the globe, but it is clear that the current technologies could not fulfill many of the demanded emerging services (e.g. Internet of Vehicles), the new type of social media enabled traffic pattern, and specifically the anticipated data storm ahead of us.

The Next-Generation Mobile Networks (NGMN) Alliance has established a Wireless 5G Initiative early this year and will announce their Wireless 5G White paper as guidelines and references for the future Wireless 5G next year. From Services and Applications point-of-view, this talk will first describe the reasons WHY we need to have “ wireless 5G” initiated now, HOW we will pursue it and WHAT will be the final results which we could anticipate to have. A few proposed features (such as Small Cell Networks, Extremely Low Latency Delay for End-to-End Wireless Networks, Smart Data Pricing, Fog Networking-based Vehicular Networks and Telematics Applications) for the future wireless 5G will be discussed.

It can be anticipated that Wireless 5G will bring consumers many disruptive technologies, applications, and services in the foreseeable future. Using IoV as an example, the speaker will present his view on opportunities, challenges, and potential solutions. He will propose a few functional features for the future wireless 5G Networking Systems. It will directly benefit to the Internet of Vehicles (IoV) and the next generation High Speed Rail (HSR) Train applications & services.

Title: Fast Data Retrieval and Processing in Cloud Storage and Computing Systems

10:00-12:00, Thursday, Feb. 19, 2015


We are in the midst of a data revolution. The total data generated by humans from the dawn of civilization upto 2003 (5 Exabytes) is now being generated every other day! Driven by a wide range of data-intensive devices and applications, this growth is expected to continue its astonishing march. To exploit the low-cost services offered by these resource-rich data centers, application developers are pushing computing and storage away from the end-devices and instead deeper into the data-centers. Hence, the end-users' experience is now  dependent on the performance of the algorithms used for data retrieval, and job scheduling within the data-centers. Our goal has been to develop the analytical foundations and methodologies to enable cloud storage and computing solutions that result in low-latency services that are so important to the end user's experience. In this talk, I will overview some of our recent research efforts at fast data retrieval and fast data processing in these large-scale data center systems. Specifically, our focus will be on the new tools and techniques required to address these challenging issues, the progress made, and the open challenges that remain.

Amir Said (IEEE Fellow)

Principal Researcher, LG Electronics, USA

Title: Future Challenges in the Implementation and Deployment of Media Processing and Compression

16:00-18:00, Thursday, Feb. 19, 2015


The dream of being “immersed” into different realities has always fascinated people, as shown by the excitement that the fictional “Holodeck” has created. However, while dreams are excellent for inspiration, professionals need to identify what is technologically feasible. In this talk we consider how technology is moving us nearer to this dream, but that to move further we need advances in many disciplines. For instance, “outside the box” issues range from human physiology and psychology to plain physics, while “inside the box” technologies range from signal processing, representation, and compression, to communications and parallel computation. We discuss some current trends, including ultra-high-definition and high-dynamic range displays, virtual reality, and light field displays, and how they are made possible by new processor architectures. Besides covering some technical problems that tend to be grossly underestimated, we also discuss the importance of not ignoring that, if not done right, immersion can produce terrible “side-effects,” like headaches and nausea.

Title: Semantics of Visual Discrimination  (PPT)

13:30-15:30, Thursday, Feb. 19, 2015


The multimedia and vision community is making great progress on image recognition using data-driven machine learning techniques.  However, given that image recognition capabilities are starting to work at a more significant scale, it is time to focus on more meaningful formulation of visual discrimination tasks.  What this requires is more careful design and modeling of the visual semantic space that supports multiple facets of visual content description across semantic concepts of people, objects, scenes, actions, activities, events, etc.  We highlight a number of semantic modeling issues related to inheritance, mutual exclusivity and completeness across the visual semantic space and discuss their important role for effective visual discriminative learning.  We demonstrate results that explore different semantic modeling techniques and study their effect on visual discrimination in different image and video data domains.
