Wireless sensor area network

Thursday 28 August 2008, The University of Auckland

*Abstract:*A network of short-range wireless, Bluetooth-enabled sensor devices with a
Backbone scaleable communication network using routers is proposed. A
topology that allows redundancy in communications has been shown by
simulation to offer more than two orders-of-magnitude improvement in
real-time packet data reliability. This is important for medical and other
systems where sensor alarms and real-time data must be reliable. A
Wireless Sensor Area Network may be integrated to the mobile telephone
system and hence the World-Wide Web. This enables remote sensing across
the world.

Example applications of networked sensors suitable for integrating to the
cellular mobile telephone system are: Voice over Internet Protocol, mobile
cameras, safe pill-dispensing using RFID tags, position determination
including Kalman filtering, UHF-RFID access monitoring and. inventory
control.

Biography: Dr. John Pollard is in the Department of Electronics at Queen Mary,
University of London, where he does research and teaching in conjunction
with Beijing University of Posts and Telecommunications (one of the top
three Universities in China). He obtained a PhD in Electronics from
Southampton University in 1968 and an MSc in Computing from Macquarie
University, Australia in 1986. He worked for 18 years in the Department
of Electronics and Electrical Engineering at University College London.

His background is in the design of Integrated Circuits, communication
systems and software systems. His theoretical work has included graph
colouring to solve routing problems in Wave Division Multiplexed optical
networks and Galois Field analysis to choose data sets for multilevel
transmission system testing. In recent years, he has been interested in
the use of the World-Wide Web as an enabling technology for teaching and
for distributed modelling and simulation software. An integrated
combination of hardware and software is necessary to connect a distributed
system of computers and mobile input/output electronics ("thin clients":
mobile telephones and Bluetooth-enabled devices) with databases and real,
physical apparatus.
