The main planned technical outputs of the TEAHA Project, are:
Specification of an open and secure framework for seamless interoperability in a global European home platform
• Development of an advanced RF solution and of an ultra low-cost powercord solution supporting seamless interworking
• Development of advanced residential gateway susbystems
Project achieved and expected results will be presented into detail during the various events which Project representatives will attend or which the TEAHA Consortium will organise, among them the annual open Forum organised in co-location with the Net-atHome™ Conference and Exhibition.
These results can also be accessed below, through the public Deliverables the Project will produce along its lifetime (zipped pdf files).
From an academic and research point of views, a number of publications on TEAHA-related topics have been released, as an exploitation effort from the partners involved in the Project and a result of a close cooperation between the industrial partners and the universities.
The following list is representative for publications on TEAHA related subjects at the University of Twente:
This paper describes the TEAHA architecture in general and the secure service discovery proces in detail:
Scholten, J and van Dijk, H.W. and De Cock, D. and Preneel, B. and Kung, A. and d'Hooge, M. (2006) Secure Service Discovery in Home Networks. In: 2006 IEEE International Conference on Consumer Electronics, 8-12 Jan 2006, Las Vegas, Nevada, USA. pp. 115-116. IEEE. ISBN 0-7803-9459-3
When home network configurations change, when new devices are added, or when devices or network directories shut down, the network must maintain a consistent state, or must be made consistent again:

This paper describes the performance of FRODO, a new service discovery protocol for home networks:

Conf. on Communication System Software and Middleware (COMSWARE), New Delhi, India. IEEE Computer Society Press.
Every service discovery protocol for home networks should be designed to function according a number of rules. These functional principles will guarantee that the system will always be, or become, in a consistent state:

A home network should maintain certain levels of QoS, even if it is used for a mix of real-time and non-real-time communications. This paper proposes such a network:

Conf. on Autonomic and Autonomous Systems and Int. Conf. on Networking and Services (ICAS/ICNS), Papeete, French Polynesia. IEEE Computer Society Press. ISBN 0-7695-2450-8
This paper presents a survey of state-of-the-art service discovery protocols:

In this paper a new dependable service discovery protocol for home networks is presented. This protocol is directory based and allows heterogeneous devices to work together:
