DEPLOY is a successful technology demonstration project showing how state of the art technology can be implemented to achieve, continuous, real‐time monitoring of a river catchment.
The DEPLOY system is a wide area network of monitoring stations delivering data in near real‐time. The demonstration sites chosen are based in the River Lee, which flows through Ireland's second largest city, Cork. The sites include monitoring stations in five zones considered typical of significant river systems and demonstrate the versatility of the technology available. Data were collected from stations at pre‐programmed intervals and transmitted to the DEPLOY servers either by short range ISM band radio or directly via the GSM GPRS network. The data were then processed and made available in a controlled manner at www.deploy.ie Findings – The project demonstrates the capability of multi‐sensor systems to remotely monitor temporal and spatial variations in water quality, through the identification of short‐term events. A system like DEPLOY could be used as a decision support tool by regulatory bodies in managing our aquatic environment with the potential to cut overall monitoring costs and provide better coverage representing long‐term trends in fluctuations of pollutant concentrations.
The demonstration of a truly heterogeneous water quality monitoring networked system was one of the first of its kind in Ireland. Based on the collected data DEPLOY can provide recommendations for water quality monitoring systems from various perspectives, technical, operational and strategic.

This paper aims to describe the simulation, design, development and characterisation of antennas for wireless sensor networks operating in a variety of environments, including an under water submarine application and more usual “open air” deployments.
The experimental test methodology, fixtures, conditions and results used to characterize the performance of these antennas (both state of the art commercially available and those developed in‐house) are presented.
The underwater test results show a near omni‐directional pattern about the three principal axes, thus showing that a spherical field has been achieved for localisation purposes (with a certain loss of resolution).
The paper focuses on the development of a new antenna scheme to enable under water communications between robotic agents.

To describe the development of a three dimensional programmable transceiver system of modular design for use as a development tool for a variety of wireless sensor node applications.
As a stepping‐stone towards the development of wireless nodes, sensor networks programme was put in place to develop a 25 mm cube module, which was modular in construction, programmable and miniaturised in form factor. This was to facilitate the development of wireless sensor networks for a variety of different applications. The nodes are used as a platform for sensing and actuating through various parameters, for use in scalable, reconfigurable distributed autonomous sensing networks in a number of research projects currently underway in the Tyndall Institute, as well as other institutes and in a variety of research programs in the area of wireless sensor networks.
The modular construction enables the heterogeneous implementation of a variety of technologies required in the arena of wireless sensor networks: Intelligence, numerical processing, memory, sensors, power supply and conditioning, all in a similar form factor. This enables rapid deployment of different sensor network nodes in an application specific fashion.
Characterisation of the transceiver module is ongoing, particularly in the field of the wireless communication platform utilized, and its capabilities.
A rapid prototyping and development cycle of application specific wireless sensor networks has been enabled by the development of this modular system.
This paper provides information about the development work and some potential application areas made available by the implementation of a miniaturised modular wireless sensor node for use in a variety of application scenarios.
With spaces at a premium at the SMART Group symposium in Newport, Gwent, on 5 June it is anticipated that a new ‘SMART Group Wales & West’ division may be formed to service the technical needs of the Welsh and West electronics manufacturing community. Congregating at the Stakis Hotel, a total of 55 individuals from electronics sites across Wales and the West were treated to a complimentary presentation and demonstration of ball grid array (BGA) technology, followed by an open forum discussion on general electronics assembly.
