Expertise:

Phuoc Tran-Gia is the head of the Dept. of Distributed Systems.
The research activities of the department focus on performance
analysis, dimensioning, and optimization of distributed systems.
Three major topics are currently matter of research using queuing
theory, probability theory, stochastic processes, simulation, and
optimization theory: (1) performance evaluation of broadband
communication systems and future IP networks, (2) planning and
analysis of mobile communication systems, (3) modelling and
analysis of manufacturing systems. With regard to the action of
COST 290 the expertise of the department lies in the traffic
modelling of Internet applications and in the performance
evaluation and planning of mobile networks. In these areas the
department had numerous cooperations with the industry including
Siemens (ICN and ICM), Nortel Networks, Vodafone Netherlands
(former Libertel), T-Mobile International, etc. Further, the
department was, with Phuoc Tran-Gia as chairman, Germany's official
representative in the European COST-257 project, which focused on
the impact of new services on the performance of broadband
networks. Now, the department participates actively in the
successor project COST-279 where Phuoc Tran-Gia serves as
vice-chairman.

Activity:
- Traffic Modelling
- Radio Network Planning
- Simulation and Performance Analysis of GPRS/UMTS networks
- congestion and admission control

Activity related to the proposed action:

Expertise:

Dirk Staehle is working at the Dept. of Distr. Systems at the Univ.
of Würzburg since 1999. During this time he was active in two
research projects with the strategic radio network planning groups
of Vodafone Netherlands (former Libertel) and T-Mobile
International. The research topic of the first project was the
Source Traffic Modelling of Wireless Applications and a simulative
study of the performance of the Internet access with GPRS based on
this traffic model. The focus of the ongoing project with
T-Mobile International is on UMTS radio network planning where
analytic methods were developed in order to derive coverage and capacity of UMTS
networks for circuit- and packet-switched traffic.

Furthermore, he is active in the COST 279 project where his focus is
also on the performance evaluation of the UMTS radio network.

Activity:
- Traffic Modelling
- Radio Network Planning
- Simulation and Performance Analysis of GPRS/UMTS networks
- congestion and admission control

Working group interest: WG1 and/or WG2
