Keynote Speech: Pathways towards Next
Generation Cognitive Ubiquitous Networks
ABSTRACT: Over the past decade, wireless communications has seen an
exponential growth and will certainly continue to witness
spectacular developments due to the emergence of new interactive
multimedia applications and highly integrated systems driven by the
rapid growth in information services and microelectronic devices. So
far, most of the current mobile systems are mainly targeted to voice
communications with low transmission rates. In the near future,
however, broadband data access at high transmission rates will be
needed to provide users packet-based connectivity to a plethora of
services. It is also almost certain that the neXt Generation (XG)
wireless systems will consist of complementary systems with a set of
different standards and technologies along with different
requirements and complementary capabilities that will offer users
ubiquitous wireless connectivity between mobile and desktop
computers, machines, game systems, cellular phones, consumer
electronic products, and other hand-held devices. A key requirement
in future wireless systems is their ability to provide broadband
connectivity with end-to-end Quality of Service (QoS), a high
network capacity, and throughput at a low cost.
This talk will present an overview of the most recent trends along
with the evolution of wireless systems. It will also describe and
discuss the challenges facing the XG broadband systems with a
special interest on cognitive ubiquitous communications networks,
cooperative communications, dynamic resource allocation, along with
cross-layer design and optimization.

Keynote Speech: Evolution and Applications
of Wireless Sensor Networks
ABSTRACT: Advances in low cost wireless and processing hardware have
stimulated a range of wireless sensor networks (WSNs) research and
their subsequent deployment in a number of applications. Since cost
is an essential factor in any development, their designs are driven
according to issues such as restricted memory size, limited
computation power and low power consumption. However advanced
applications such as those demanded by the medical/health care,
military and surveillance sectors require higher levels of network
performance supporting time sensitive, guaranteed and secure high
quality data delivery. These demanding applications drive the need
to enhance first generation WSN concepts.
The presentation will address the basic characteristics of WSN
solutions and highlight some of the applications that have been
addressed. It will then go on to consider some of the near term
enhancements such as network management, mobility support, secure
and high quality data delivery. Utilising ‘cognitive’ techniques
will aid in the management of complex network environments through
observing, providing feedback, learning, and making decisions that
optimize performance; mobility support is important for the
applications characetrised by frequent topological change. This
approach not only facilitates the establishment of robust routing
paths for mobile nodes but also provides a time-varying topological
view to a manager that has beneficial effects on data collection
tasks. The transport layer, the lowest layer that secures the
end-to-end communication and is responsible for congestion
avoidance, can be addressed to yield secure data delivery at a
pre-defined quality of service level. There are obvious
ramifications of implementing these features placing severe demands
on the existing hardware platforms; therefore, a new hardware
designs are required. Taking into consideration the demand for these
applications, it is reasonable to expect that the cost of deploying
these enhancements will be higher than that of traditional WSN based
solutions.

Plenary Speech: Microstructured Optical Fibers
and Their Use in Communications and Sensing Applications
Perry Ping SHUM and Yehuda LEVIATAN
ABSTRACT: Specialty
fibers have been widely investigated over the past few years
worldwide. In the past decade, they have moved from being an
intriguing laboratory curiosity to become a new frontier in the
development of optical fibers. These new fibers have micron-scale –
or even nanoscale – air-holes running down their length, which
influence or define their waveguiding characteristics. The inclusion
of such air holes in an optical fiber has resulted in a wide range
of novel waveguiding designs and effects, greatly extending the
possibilities of some fields while making others possible for the
first time. Generalized models such as FDM, FDTD, and SMT for modal
analysis of PCF have been developed. Photonic bandgap fibers,
record-breaking low-loss all solid fibers, multicore structures, and
even nanostructure core fibers have been proposed and fabricated.
Novel fiber based devices, ranging from gratings, couplers, and
sensors have been explored for application of optical communication
systems as well as sensing technologies.
