Abstract
Sentient computing is a form of ubiquitous computing which emphasizes the use
of sensors to perceive its environment and react accordingly. It interacts cl
osely with people and performs intelligent actions which affect and benefit pe
ople. Ultra Wide Band (UWB) technology, with characteristics such as low power
consumption, capability for high and low data rate wireless communications an
d accurate localization, is an excellent wireless technology for sentient comp
uting. In April 2006, the Science & Engineering Research Council (SERC) of the
Agency for Science, Technology and Research (A*STAR) of Singapore approved th
e funding of the Ultra Wide Band-enabled Sentient Computing (UWB-SC) Thematic
Strategic Research Programme (TSRP) which covers eight areas of research: UWB
antennas, RF transceivers, digital signal processing, baseband signal design a
nd processing, localization and identification, MAC with Quality of Service (
QoS) for sensor networks, intelligent audio and video processing for smart spa
ces and context-aware middleware. Research is being carried out by about 42 re
searchers at the Institute for Infocomm Research (I2R), Institute of Microelec
tronics (IME), Nanyang Technological University (NTU) and National University
of Singapore (NUS). While this TSRP strives to achieve good system performanc
e in terms of high data rate, long transmission range, and accurate event dete
ction, significant emphasis has been placed on low power designs, energy effic
iency/robustness through advanced resource management, and agility to support
sentient applications through a context-aware infrastructure. The core techno
logies and research outcomes have been demonstrated using a homecare scenario
and a personalized shopping scenario as the primary demonstrable vehicle. This talk first overview the UWB-SC program and its current status, then focus
es the presentation on the research and development of Coalition – a context
aware system infrastructure for the UWB-SC. The motivation of the project will
be presented, the design objectives and several design considerations will be
explained next, following by the presentation of the system architecture, the
design of a prototype, and a summary of results obtained so far. Lastly, an
overview of the status of the UWB-SC program will also be given. Bio-data of the Speaker:
Dr Hung Keng Pung received his BSc in Communications Engineering and his PhD i
n Electronics from the University of Kent at Canterbury, UK, in 1981 and 1985,
respectively. Since 1986 he has been with the School of Computing (SoC) of th
e National University of Singapore, and is an Associate Professor. He was a me
mber of the executive committee of SingAREN (2004-2007 ), a co-founder of the
IEEE International Conference on Networks (ICON), a member of IEEE and ACM, an
d a past deputy chairman of IEEE Singapore Section. He is as a guest editor fo
r International Journal on Network Management (Wiley), Computer Communications
and LNCS of Springer.
Dr Pung currently heads the Networks Systems and Services Laboratory as well a
s holding a joint appointment as a Principal Research Scientist at the Institu
te of Infocomm Research (I2R) in Singapore. He teaches courses in ‘mobile and
multimedia networking’ and ‘advanced topics in networking’ at senior under
graduate level and postgraduate level respectively. His areas of research have
spanned from MAC protocols, distributed systems design, wireless and multimed
ia networking and quality of service management, to context-aware systems and
ubiquitous pervasive computing. He has published approximately 150 papers in i
nternational journal and conferences, has two USA patents pending, and is a te
chnical advisor to a mobile e-commerce start-up company.
