Professor Walke received his diploma and doctor's degree in 1965 and
1975, both from the Department of Electrical and Electronics
Engineering, University of Stuttgart, FRG.
From 1965 to 1983, he first served at the AEG-TELEFUNKEN Research
Institute at Ulm/FRG and later as a department head in the AEG
Division for High Frequency Techniques, where he evaluated performance
of computer systems and designed computer based data communications
networks.
1983 he joined the Department of Electrical and Electronics
Engineering at FernUniversity of Hagen as a full professor for
Dataprocessing Techniques, where he established a research group of
about 10 scientists, most of them funded by external sources.
1990 Dr. Walke joined Aachen University of Technology as a full
professor for Communication Networks (COMNETS) and took over
responsibility for lectures in Applied Computer Science, Datacommunication
Networks & Protocols, Traffic Theory for Performance Analysis, and for
Mobile Radio Networks. He currently leads a research group working in
the areas of
mobile radio and fixed network services and protocols,
queueing theory and stochastic simulation for performance evaluation,
design and formal specification (SDL) of communication protocols.
His research interests are in formal specification, modeling,
mathematical and simulative analysis, and pilot implementation of
protocols and services for communications networks. Current work
covers
mobile radio propagation modeling,
mobile cellular and satellite communications protocols,
dynamic channel assignment,
handover control in multilayer cellular systems,
design tools for mobile radio networks,
wireless ATM for residentials, LANs, cellular,
single/multi-hop packet radio,
N-/B-ISDN modeling & protocol analysis,
radio networks for transport support,
local and metropolitan area networks.
75% of the scientific research personnel is funded
externally. Research projects, currently, are granted by
Deutsche Forschungsgemeinschaft, DFG,
ACTS and Telematics programmes of the European Union,
German communications industry,
Federal Ministry of Research and Development,
Ministry of Research and Development of North Rhine Westfalia,
Federal Office of Post and Telecommunications,
others.
The research staff at COMNETS currently has 29 full-time members and
about 30 students assistants. About 60 diploma theses are finished per
year.
Prof. Walke's scientific work comprises about 80 scientific papers
and four textbooks, in the fields of modelling and performance
evaluation of computer and communication systems. 1975 he earned the
ITG-Best Paper Award.

1982 as a member of GI (German Computer Society) Technical
Committee 3.2.,
1988 as a member of ITG (German Information Technology Society)
Technical Committee 4.1,
1988 to 1992 as Technical Auditor in the RACE programme (later
as Evaluator also),
1993 as programme committee chairman for ITG-Conference ``Mobile
Radio Communications'',
1993 as programme committee chairman for GI/ITG-Conference on
Measurement, Modelling and Performance Evaluation of Computer and
Communications Systems,
1994 as member of the programme committee of IEEE Conference on
Personal and Indoors Mobile Radio Communications (PIMRC),
1994 as a member of Board of the German Information Society
(ITG),
1994 as a member of the German Branch of the International
Informatization Academy, Moscow, Russia,
1994 as a Vice Dean of the Faculty of Electrical and Electronics
Engineering, Aachen University of Technology,
1995 as the speaker of the Focusprojekt Mobilkommunikation, a
division of ITG,
1996 as the Leader of the Systems Definition Group of the German
national research programme ATMmobil (Wireless ATM systems for
multimedia applications),
1996 as the chairman of the Programme Committee of EPMCC'97, the
2. European Personal and mobile radio Communications Conference.
1989 he served to the German Minister of Post and Telecommunications
as a technical evaluator of the proposed system designs submitted by
industry consortia competing for the license of the GSM-based D2
network in Germany. 1992 he served in the Central Group of the German
Minister of Post and Telecommunications, responsible to grant a
licence for the GSM-based E1 network. 1995 he consulted the German
Minister of Post and Telecommunications in the preparation phase of
licensing DECT to be used for the Wireless Local Loop.
