Abstract

Due to the recent advancement in motion capture hardware and motion-based applications, human motion analysis has become an increasingly popular research area. Its core problem is to model human motion in a meaningful way, such that we can generalize knowledge to recognize, analyze and synthesize movement. Motion related applications nowadays such as motion-based gaming, 3D character animation, autonomous surveillance and smart robots are the results of the area. The problem of human motion analysis is important as it connects different research fields. Taking an example of motion gaming with the Microsoft Kinect, the system first applies computer vision techniques to identify human body parts. Then, artificial intelligence is introduced to understand the meaning of the movement and perform human-computer interaction. Virtual reality techniques based on movement are sometimes used to enhance gaming immersiveness. Character animation and graphical rendering algorithms are implemented to render the controlled virtual character. In this talk, I will discuss the importance of human motion analysis in computer science. With the support of my research projects, I will demonstrate how motion analysis can connect different research fields, including computer graphics, games and vision. I will show how my projects achieve impact in research and the society, and conclude my presentation with future opportunities and potential directions.

Lecture Meeting (IEEE ComSoc Distinguished Lecturer Tour (DLT)): Apr 17, 2017

Title

Customized Mobile Networking in 5G

Lecturer

Prof. Tarik Taleb
School of Electrical Engineering,
Aalto University, Finland

Abstract

The telecom industry keeps reinventing itself. Soon, the world will be experiencing the 5th generation mobile networks (5G). These 5G mobile systems are expected to meet different strict requirements beyond the traditional operator use cases. Major obstacles to overcome in 5G systems are principally the highly-centralized architecture of mobile networks along with the static provisioning and configuration of network nodes built on dedicated hardware components. This has resulted in lack of elasticity and flexibility in deployment of mobile networks; rendering their run-time management costly, cumbersome and time-consuming.

On the other hand, mobile networks are nowadays architected to serve all mobile users; ensuring some degree of service-level differentiation, by making decisions on different user profiles, but with no specific tailoring of the functioning to the specific user needs. However, statistics demonstrate that users do not behave all in the same way. Furthermore, a single mobile network usually ensures the communication for all service types, regardless of the suitability of its available functionality to deliver these services with acceptable Quality of Experience and network efficiency. It becomes then apparent that having the same mobile network architecture serving all mobile users, let alone all mobile applications, despite the diversity they exhibit in their attitudinal response to mobile services, have to be rethought.

5G systems need to accommodate elasticity, flexibility, dynamicity, scalability, manageability, agility and customization along with different levels of service delivery parameters according with the service requirements. For this purpose, different requirements have to be met and numerous associated challenges have to be subsequently tackled. This talk will touch upon the recent trends the mobile telecommunications market is experiencing and discuss the challenges these trends are representing to mobile network operators. To cope with these trends, the talk will then showcase the feasibility of on-demand creation of cloud-based elastic mobile networks, along with their lifecycle management. The talk will introduce a set of technologies and key architectural elements to realize such vision, turning end-to-end mobile networking into software engineering. The talk will particularly showcase the need for the deep customization of mobile networks at different granularity levels: per network, per application, per group of users, per individual users and even per data of users. The talk will also assess the potential of Network Function Virtualization, Software Defined Networking and Network Slicing to provide the appropriate customization and highlights the technology challenges. The talk will also elaborate on a high level architectural solution addressing a massive multi-slice environment.

Title

Research into Radio Environment Maps for Emerging 5G and IoT Networks

Lecturer

Eryk Dutkiewicz, Dr., Professor
School of Computing and Communications
University of Technology Sydney, Australia

Abstract

The high demand for wireless Internet including emerging Internet of Things (IoT) applications is putting extreme pressure on better utilisation of the available radio spectrum. The expected spectrum "crunch" requires highly efficient radio resource management schemes with low complexity and high responsiveness to the changing network conditions. Spectrum sharing is regarded as an essential approach to regaining access to otherwise unused spectrum and it is considered an essential component in the development of IoT and 5G networks. Spectrum sharing can be conducted at different time scales. As the time scale of the operation of spectrum sharing decreases, the possibility for utilising more available spectrum holes increases. However, the shorter time scale brings with it challenges. Efficient decisions regarding the use of spectrum sharing require accurate knowledge of the spatial and temporal spectrum use in a geographical area of interest. This knowledge can be represented in Radio Environment Maps which need to be generated efficiently and accurately. In this presentation we give an overview of the spectrum sharing concept and its emergence in standards activities for IoT and 5G networks. We also present our research on spectrum sharing including theoretical methods for efficient and accurate generation of Radio Environmental Maps and radio spectrum measurements campaigns on UTS campus in Sydney to enable Smart Building and Smart City IoT applications.

Title

Markov Modelling: from Wi-Fi to 5G and Beyond

Lecturer

Ren Ping Liu, Dr., Professor
School of Computing and Communications
University of Technology Sydney, Australia

Abstract

Markov chain is the main analytical tool for IEEE 802.11 modelling and analysis. However, existing 2-dimensional (2-D) Markov chain models of Wi-Fi systems are unable to capture the complete QoS performance and queueing behaviour due to the lack of an adequate finite buffer model. We propose a 3-dimensional (3-D) Markov chain that integrates the 802.11 system contention resolution and queueing processes into one model. The 3rd dimension, that models the queue length, allows us to accurately capture important QoS measures, delay and loss, plus throughput and queue length, for realistic 802.11 systems with finite buffer under finite load.

The Markov theory has since been extended and applied in other areas, leading to many research outcomes, including vehicular networks (VANET), WiFi localization, energy efficient design in the Internet of Things (IoT), and recently coexistence design and analysis of LTE in unlicensed spectrum under the LAA/5G framework.

Title

Achieving High-Speed Aerial Backbone Transmission for Air-Space-Ground Integrated Information Networks

Lecturer

Xiaojing Huang, Dr., Professor
School of Computing and Communications
University of Technology Sydney, Australia

Abstract

Air-space-ground integrated communication and networking is one of the most important targets of global research and development efforts. High-speed aerial backbones are the key components of such space information networks since they interconnect the spaceborne, airborne and ground based transmission platforms to form a seamless communications system. Currently, there have been some significant advances in spaceborne based communications networks. As the 5G mobile system emerges, ground based networks are also becoming more and more mature. However, there are still significant challenges in achieving high-speed aerial backbone links for the airborne based communications networks. This presentation gives a brief overview of current state-of-the-art in airborne based backbone technologies, and discusses how to realize high-speed transmission for air-to-air links and air-to-ground links from a high-altitude aerial platform using millimetre wave, multiple input multiple output, and full-duplex technologies. Research directions for achieving low cost and high flexibility aerial backbones using unmanned aerial vehicles are also suggested.

Abstract

The wireless communication systems have dramatically changed the world by connecting people and devices in recent years. We are currently standing at the 4th generation (4G) in the evolution and drawing the picture for the next generation (5G) wireless communication systems. For which, we are aiming at 1000x increase of the capacity. Despite all efforts on the coding and modulation techniques, the growth of capacity is physically restricted by the limited spectrum resource. Therefore, spectrum sharing has been proposed to break this constraint. Our work on the current spectrum sharing frameworks includes two main spectrum sharing frameworks: Spectrum Access System (SAS) in U.S and Licensed Shared Access (LSA) in Europe. We address the common and differing factors then propose access and interference mitigation methods for SAS and LSA. SAS is a hierarchical access model with three tiers of users – incumbents, Priority Access Licensees (PAL) and General Authorised Access (GAA) users. We propose a PAL-GAA co-channel interference mitigation technique that does not expose base station locations. The distribution of the aggregated interference is derived using Probability Density Function and Characteristic Function. The optimal exclusion zone size is found through an approximation of a convex problem and our approach reduces the exclusion zone size substantially. We also propose the access and coexistence methods between different tiers in LSA and SAS.

Abstract

Radio Frequency (RF) energy harvesting has experienced a rapid development in recent years due to the increasing number of RF transmitter sources producing an abundant ambient microwave energy waste. Furthermore, the development of wireless power transmission (WPT) technologies has triggered impetus for RF energy harvesting. Hence, RF energy scavenging is a promising solution as it has the potential to provide a sustainable energy source to meet upcoming demands. Efficient ambient RF energy scavenging is a very challenging issue, as it deals with the low RF power levels available in the environment. The scavengeable power levels are generally unknown and can vary unpredictably; therefore sparking research interest to develop highly sensitive RF energy scavengers to capture ambient RF signals over a range of low input power levels. Her research focuses on a real life RF energy scavenging approach to generate electrical power in urban environments. During my PhD, I developed highly sensitive and efficient ambient RF energy scavenging system and method to harvest a broad range of very low level ambient RF power.
