Wireless sensor networks for activity monitoring in safety critical applications

Rednic R., Gaura E.I., Brusey J., Coventry University, UK

The ability to monitor posture is essential to many application areas, including virtual reality, health, and sports applications. The work here focuses on the use of postural monitoring monitoring in safety critical missions such as [...]

Priority Based Message Transmission over Unreliable Wireless Links for Safety Critical Monitoring Applications

Fei X., Kemp J., Gaura E.I., Brusey J., Cogent Computing Applied Research Centre, Coventry University, UK

In our prior work, a Body Sensor Network (BSN) system aimed at increasing safety of bomb disposal operatives during missions has been developed. Although this system served well the application at hand in terms of [...]

A down-to-earth case for autonomy in massively plural sensor systems

Newman R.M., Gaura E.I., Brusey J.P., Coventry University, UK

The role of autonomy in wireless sensor networks remains something of a controversial issue. Although most of the early work in the field, and the subsequent research agenda, has implicitly assumed the use of autonomous [...]

Size does matter – the case for big motes

Newman R.M., Gaura E.I., Coventry University, UK

An account is given of the two scools of mote design for wireless sensor networks, the maxi-mote and the mini-mote. Both approaches have their advantages, but it is argued that the maxi-mote approach is more [...]

Experimental Localization with MICA2 Motes

Allen M.P., Gaura E.I., Newman R.M., Mount S.N.I., Coventry University, UK

As research into Wireless Sensor Networks (WSNs) increases, it becomes more and more apparent that knowledge of sensors’ physical position within a network is a necessity. A sensor’s data are only useful if put in [...]

A Simulation Tool for System Services in Ad-Hoc Wireless Sensor Networks

Mount S.N.I., Newman R.M., Gaura E.I., Coventry University, UK

Whilst the physical design and instrumentation of ad-hoc wireless sensor networks (WSNs) has recently received a lot of attention, it is often assumed that the system software for such devices will simply copy the design [...]

A Realistic Dream – a Top-Down Feasibility Study for MEMS Planetary Exploration

Newman R.M., Gaura E.I., Tabor J., Mount S., Coventry University, UK

A feasibility study of a 'dream application', detailing the technological requirements, and using them to produce the design of a sensor node in a top-down manner, in order to establish the feasibility of the scenario [...]

System Issues in Arrays of Autonomous Intelligent Sensors

Newman R.M., Gaura E.I., Conventry University, UK

This paper considers some of the systems level issues of concerned when building of large scale sensing systems composed of a large number of autonomous intelligent sensors. The work is motivated by the potential offered [...]

Closed-Loop, Neural Network Controlled Accelerometer Design

Gaura E.I., Ferreira N., Rider R.J., Steele N., Coventry University, UK

In this paper, a closed-loop, smart transducer design is proposed, based on artificial neural network (ANN) techniques. The design aims to improve the performance of open-loop, off-the-shelf capacitive acceleration sensors and increase their robustness to [...]

A Neural Network Approach for the Identification of Micromachined Accelerometers

Gaura E.I., Steele N., Rider R.J., Coventry University, UK

The paper presents the identification procedure for a nonlinear accelerometer using a neural network. Simulation results obtained in SPICE and Matlab show good agreement between the behaviour of the sensor over its entire working range [...]
