On Maximizing the Probability of Achieving Deadlines in Communication Networks

Autor: Benjamin Becker, Christian Oberli, Tobias Meuser, Ralf Steinmetz

Publikováno v: Journal of Sensor and Actuator Networks, Vol 13, Iss 1, p 9 (2024)

We consider the problem of meeting deadline constraints in wireless communication networks. Fulfilling deadlines depends heavily on the routing algorithm used. We study this dependence generically for a broad class of routing algorithms. For analyzin

Autor: Viktor Wendel, Marc-André Bär, Robert Hahn, Benedict Jahn, Max Mehltretter, Stefan Göbel, Ralf Steinmetz

Publikováno v: EAI Endorsed Transactions on Serious Games, Vol 1, Iss 4, Pp 1-10 (2015)

One major Serious Games challenge is adaptation of game-based learning environments towards the needs of players with heterogeneous player and learner traits. For both an instructor or an algorithmic adaptation mechanism it is vital to have knowledge

A Survey on Security in Mobile Peer-to-Peer Architectures—Overlay-Based vs. Underlay-Based Approaches

Autor: Christian Gottron, André König, Ralf Steinmetz

Publikováno v: Future Internet, Vol 2, Iss 4, Pp 505-532 (2010)

Mobile Ad hoc networks (MANET) and Peer-to-Peer (P2P) networks share central characteristics such as their distributed and decentralized nature. Combining both networking paradigms results in a Mobile Peer-to-Peer (MP2P) system that operates independ

The Two-Step P2P Simulation Approach

Autor: Hannes Birck, Oliver Heckmann, Andreas Mauthe, Ralf Steinmetz

Publikováno v: Journal of Communications Software and Systems, Vol 1, Iss 1, Pp 4-12 (2005)

In this article a framework is introduced that can be used to analyse the effects & requirements of P2P applications onapplication and on network layer. P2P applications are complex and deployed on a large scale, pure packet level simulations do not

Handwriting: Feature Correlation Analysis for Biometric Hashes

Autor: Ralf Steinmetz, Claus Vielhauer

Publikováno v: EURASIP Journal on Advances in Signal Processing, Vol 2004, Iss 4, Pp 542-558 (2004)

In the application domain of electronic commerce, biometric authentication can provide one possible solution for the key management problem. Besides server-based approaches, methods of deriving digital keys directly from biometric measures appear to
