Each tutorial duration will be half day.
T1: Interference Alignment: A new look at Signal Dimensions in Interference Networks (Tuesday AM)
Presenter: Syed A. Jafar, University of California Irvine, USA
The Shannon capacity of wireless networks is the holy grail of network information theory. Recently, this area has seen a burst of activity leading to remarkable progress on a variety of problems including the capacity of interference networks, X networks, cellular networks, multicast and compound broadcast networks, tactical communication networks with secrecy and jamming issues, cooperative communication networks, cognitive radio networks, and network coding for multiple unicast networks and distributed data storage networks. While each communication scenario has its own peculiarities, a common thread running through a vast number these recent developments is the new idea of interference alignment. Read more here ...
T2: Heterogeneous Cellular Networks: WCDMA, LTE and Beyond (Tuesday PM)
Presenter: Mark C. Reed, Australian National University/UNSW, Australia
Wireless broadband is forecast to increase by 26 times in the next 4 years (Cisco). Current outdoor wireless networks will not be able to scale to this demand. Industry and research has recognised that small cell technology (femtocells) can provide significant data offload while using the same frequencies. Heterogeneous wireless cellular networks are an evolution of this and utilize multiple tiers of cells to serve users. Leveraging the low-cost femtocell technology (essentially a low-power wireless access points for cellular technology) that operate in licensed spectrum to connect standard mobile devices to a mobile operator’s network. Heterogeneous wireless networks enable a much lower cost wireless deployment architecture with orders of magnitude increase in overall data throughput per unit area. Read more here ...
T3: Wireless Body Area Networks: Forming a Wearable Intranet (Tuesday PM)
Presenter: David Smith, National ICT Australia, Australia
Wireless Body-area-networks (BAN's) represent the humanization of the internet of things – moving wireless sensor networks onto and even inside the human body. Applications of BAN's touch every aspect of health, fitness, occupational and everyday living, and include critical care, elite/amateur sports, military personnel and consumer entertainment. With the promise of such networks to improve human monitoring, comes the challenge of making unobtrusive and reliable ambient wireless systems. The aim of this tutorial is to provide a context of wireless standardization (in particular the recently approved IEEE 802.15.6) and research challenges that impact on body-area-networking. The requirements and motivation of BAN's based on several real-world scenarios will be outlined. Interaction between application layers and wireless protocols and radio schemes required to service them will be shown. Read more here ...
T4: Base Station Cooperation in Cellular Networks (Tuesday PM)
Presenter: Stephen Hanly, Macquarie University, Australia
In this tutorial, we will cover the exciting new area of Network MIMO. In recent years, much attention has been focused on the poor cell edge user who requires more transmit power, gets more interference, and typically receives a lower quality of service. "Network MIMO", or "Cooperating Base Stations", provides a way to avoid all the problems of the cell edge user, as well as increase coverage, lower energy consumption, and improve total capacity, all at the same time. However, most of this has been shown in theory, and there are practical constraints to consider, such as complexity, backhaul bandwidth, and channel state measurement and feedback. Nevertheless, such approaches are indeed under consideration for next generation cellular systems, for example so-called Coordinated Multipoint (CoMP) in 3GPP LTE-Advanced. Read more here ...
T5: Wireless Sensor Networks for a Sustainable Future (Tuesday AM)
Presenters: Elena Gaura and James Brusey, Coventry University, UK
Wireless Sensor Networks (WSNs) have repeatedly proven themselves as enablers of understanding in a variety of science and society domains characterized by spatio-temporal, multivariate complexity. Examples abound of WSN deployments which have enriched the knowledge base and contributed to better scientific characterization of habitats, glaciers and climate change, volcanoes and ocean floors. Whilst not yet widespread in the industrial world, the use of WSN systems for monitoring, evaluation and control of processes and structures is growing. And with it, the designers’ ability to deliver reliable WSN products has grown exponentially over the past few years. When widely adopted, the WSN technology, supported by miniature sensors and cheap computing power is likely to induce a new information revolution. Read more here ...
