Towards A Framework For Modelling Multimedia Conferencing Calls In The Next Generation Network, Gavin Byrne, Declan Barber Nov 2015

Towards A Framework For Modelling Multimedia Conferencing Calls In The Next Generation Network, Gavin Byrne, Declan Barber

The ITB Journal

This paper is concerned with the creation of a multiparty multimedia conferencing application which can be used in Next Generation Networks. It begins by suggesting ways in which conferencing can be modeled with a focus on separating signaling and media transfer functionality. Enabling technologies which could support the modeling framework derived and which are compatible with Next Generation Network (NGN) principles are reviewed. Finally, a design and implementation for a simple multimedia conferencing application are described.


Embedded Systems In A Mobile Distributed Ip Network, Conor Gildea, Declan Barber Nov 2015

Embedded Systems In A Mobile Distributed Ip Network, Conor Gildea, Declan Barber

The ITB Journal

This paper describes an approach to the internetworking of mobile IP sensor nodes in a converged network environment. This preliminary investigation of sensory network models is driven by a joint applied research project between ITB and Teagasc (Grange) which seeks to establish the feasibility of the real-time remote monitoring of animal welfare while in transit between Ireland, Europe and the Middle East. The paper examines traditional system architectures, messaging paradigms and protocols with a view to establishing how the trend towards convergence in telecommunications and the emergence of new Internet Protocols could support the creation of new modes of operation ...


Unified Messaging Systems: An Evolutionary Overview, Declan Barber Nov 2015

Unified Messaging Systems: An Evolutionary Overview, Declan Barber

The ITB Journal

Over the last decade, the widespread demand and use of the internet has changed the direction of the telecommunications industry as it was recognised that the internet could be used as an inexpensive way to handle not only data but also voice communications. This convergence of traditional voice and data technologies towards an IP-based open architecture has been paralleled by a convergence of the internet and mobile communications. As a result of these convergences, unified messaging has emerged as a technically viable service. Integrated messaging services that offer partial unification of different message types are already in the marketplace. This ...


An Xml Framework For The Structured Data Exchange Between Medical Devices, Ulrich Neuhaus, Paul Walsh Nov 2015

An Xml Framework For The Structured Data Exchange Between Medical Devices, Ulrich Neuhaus, Paul Walsh

The ITB Journal

This paper describes an XML framework for the exchange of data between medical devices and software systems. XML technologies offer an extensible data format, which is easy to both create and process and simplifies the exchange of data. Different XML standards are defined within the framework in order to provide a practical solution for both device manufacturers and software developers. The structure and benefits of XML documents are discussed and an XML framework for ophthalmology is described.


Longer Than A Telephone Wire - Voice Firewalls To Counter Ubiquitous Lie Detection, Carl Reynolds, Matt Smith, Mark Woodman Nov 2015

Longer Than A Telephone Wire - Voice Firewalls To Counter Ubiquitous Lie Detection, Carl Reynolds, Matt Smith, Mark Woodman

The ITB Journal

Mobile computing and communication devices are open to surreptitious privacy attacks using emotion detection techniques; largely utilising work carried out in the area of voice stress analysis (VSA). This paper extends some work in the area of removing emotion cues in the voice, specifically focusing on lie detection and presents the results of a pilot study indicating that the use of mobile phones in situations of stress is common and that awareness of VSA is low. Existing strategies for the removal or modification of emotion cues, based on models of synthesis are considered and weaknesses are identified.


Globalcom, Declan Barber, Conor Gildea, Gavin Byrne Nov 2015

Globalcom, Declan Barber, Conor Gildea, Gavin Byrne

The ITB Journal

The objective of this developed application is to provide a company with a means of communicating with its employees no matter where they are physically located and what communication resources they may have at any particular time. The core focus of this application is to provide a Unified Messaging System using synchronous and asynchronous forms.


The Role Of Cryptography In Security For Electronic Commerce, Ann Murphy, David Murphy Nov 2015

The Role Of Cryptography In Security For Electronic Commerce, Ann Murphy, David Murphy

The ITB Journal

Many businesses and consumers are wary of conducting business over the Internet due to a perceived lack of security. Electronic business is subject to a variety of threats such as unauthorised access, misappropriation, alteration and destruction of both data and systems. This paper explores the major security concerns of businesses and users and describes the cryptographic techniques used to reduce such risks.


Xml For Business To Business Data Exchange, Geraldine Gray, David Kerwick Nov 2015

Xml For Business To Business Data Exchange, Geraldine Gray, David Kerwick

The ITB Journal

This paper examines to use of XML for business to business data exchange. Starting with creating an XML document from an existing data source and transmitting that document, we explain some of the supporting standards for XML which facilitate automated processing and transformation of an XML document. Finally we look at the advantages of using XML, and why it is expected to revolutionise electronic data interchange.
