Abstract

The focus of this paper is to outline the research undertaken of Wireless Sensor Net-works and how they can be used to assist in home health and safety applications. The
particular area of interest is a computer controlled system that tracks a wireless sensor attached to a child indoors for the purpose of alarming when the child enters a prede-termined unsafe area. The system must also define boundaries and have the ability to alert a parent/guardian in the case of the boundaries being breached.

A thorough review of the available literature was undertaken which gave the author background information as to techniques for localisation and their suitability in indoor applications.

An empirical approach to localisation using the Profiling/Fingerprinting method was used. A centralised system design was implemented and an application called Adapt-able Infant Monitoring System was written and tested to perform the localisation and boundary alarming and to provide the ability for remote location retrieval via storing relevant data in a database.

Algorithms were proposed to reduce the localisation error. These algorithms have been rigorously tested in two scenarios. A baseline test was applied to create a benchmark, then testing was applied to a real residential situation. The results are analysed and discussed.

The results concluded that localisation using the specified hardware and the finger-printing technique was inadequate for the application domain. Factors attributing to the localisation error have been discussed including irregular radio signal propogation which has been earmarked for further work.

The localisation accuracy does not render the research work invalid. Providing an omni-directional radio signal and additional research and testing will see the full potential of the system design.
The system proposed in this research allows for user-defined boundaries to be set for the alarming mechanism. This feature alone provides, versatility and expandability which is one of a kind and has potiential to enter the market-place covering unlimited application scenarios.
