Technology Lecture on Adaptive Self-Organisation, Navigation, and Sampling for Mobile Wireless Sensor Networks

Date: 13 May 2009 - 13 May 2009

Venue: Auditorium, Level 3, SIMTech Tower Block

Abstract
Wireless sensor networks (WSN) may consist of heterogeneous nodes, including mobile units, fixed ground sensors, and human user nodes.  WSN should be deployable and quickly programmable with multiple missions for security assessment and event alarm capability.  A WSN is a distributed computing grid that should be as easy to program as a laptop PC.  WSN should have certain self-organising and autonomous adaptive features so that it can be useful to humans and not burden the user with unnecessary details and unneeded decisions.  The WSN should function as a decision and alarm aid to effectively extend the range and situation awareness of human users to distances impossible for human sensing and modalities not sensed by humans (e.g. ultrasound, IR).

Topics to be covered include:
- several aspects of self-organising and autonomous behaviour in WSN developed at Automation & Robotics Research Institute (ARRI), University of Texas (UTA), by Dan Popa and F L Lewis. The goal is a complete dynamical framework that allows fast programming of deployable WSN, and facilitates both computer simulation analysis and efficient on-line implementation
- novel methods for dynamic Adaptive Localisation, whereby a WSN self-configures on deployment to form a coordinate system for reference of events and targets subsequently perceived by the sensor network
- Adaptive Sampling, whereby the mobile nodes of the WSN are sent to the most useful locales to quickly estimate sensor fields such as temperatures, water contaminants and salinity, etc.
- a method of cross-layer navigation is detailed that allows achievement of goals, obstacle avoidance, battery conservation, and guaranteed communications under a common framework
- some issues about sensor placement and coverage, and WSN lifetimes
- a method for multi-static radar target tracking using Ultra-Wideband (UWB)
- the WSN Distributed Intelligence and Autonomy Lab (DIAL) at ARRI, giving some ideas for developing a complete WSN testbed
Many of the above ideas have actually been implemented on the DIAL WSN
