Project Overview

NOMAD logo

The NOMAD (Next-generation wireless software services: Modelling and Developing usable applications) consortium was formed, which combined research groupings from three Institutes of Technology: The Centre for Creative Technologies and Applications (CCTA) at IADT; The Telecommunications Software Systems Group (TSSG) at Waterford IT; and The Software Technology Research Centre (SToRC) at Dundalk IT. The rationale behind the consortium, which received €350,000 in funding, was to address new application areas where there is a strong emphasis on supporting creative activities at a time and place of the user’s choosing.

NOMAD’s first trial ran in IADT between the 10th or February 2004 and the 19th of February. The preparation of the trial involved heavy cooperation between all partners including a number of meetings one of which was held in TSSG. TSSG was primarily involved in software platform development and trial infrastructure. The software development was closely tied to the software services development going on in Dundalk IT and both teams were in constant contact. On the infrastructure side, TSSG specified the PDA hardware to be bought and also specified the wireless equipment as well purchased it. TSSG loaned the server for hosting the software components to IADT for the duration of the trial.

Just before the trial TSSG personnel supported by IADT staff installed the wireless network on the IADT campus. During the trial TSSG provided software and hardware support to the IADT trial coordinator. As the trial was coming to its conclusion TSSG arranged publicity on a number of major news web sites and in some local press. In autumn 2004, two postgraduate students partially involved in NOMAD finished their Masters.

Darach Cawley discussed the “Development of Smart Services for Smart Spaces”. For developing these smart services, he proposed a Smart Engine, which provides the ability to gather, collate and evaluate context information, on behalf of traditional, non-context-aware services. The implementation, testing and integration of the Smart Engine and the developed traditional services were part of his work.

Stephen Greene discussed “Context-Aware Wireless Service System Infrastructure and Implementation”. This system, CAWSS, takes advantage of context information in order to tailor its operations and provides this information to any services that request it. It also offers a large library of user/service management functionality to the services. Communication functionality provides services with the capability to send messages to users and other services via a number of different channels.

In preparation of the second trial, where the TSSG team focuses 2005 on the delivery of positioning information from a variety of sources, a Synergetic Positioning Architecture for Location-dependent Services has been designed. It allows to combine multiple methods to recalibrate each other by means of data fusion. A novel architecture processes the data from pervasive devices penetrating everyday objects to the cheapest level. The synergetic heterogeneity of completely different recognition principles allows to tailor the perceived positioning probability to the specific requirements of the target application.

Two postgraduate students worked on these topics. Andrew Betson analysed in his thesis the centralisation of the data collection from multiple systems, opening up the potential to fuse different data sources together to achieve a level of accuracy not available using individual systems alone. Kieran Sullivan investigated the fusion algorithms available and evaluates their suitability for massive, heterogeneous data input.


The project ran from October 2002 and was completed December 2005.

Project Achievements

Since the collection of context and location data rises privacy issues, several approaches to maintain privacy and security were pursued. This comprises a number of obfuscation methods, dependent on the requirements of the specific application, such as anonymisation, or dilution of location resolution.
