"Message Identification and Its Role in Molecular Communication Systems"
ABSTRACT: The concept of message identification was introduced by Ahlswede and Dueck in 1989, building on earlier ideas by Jaja in 1985. Their results in the field of information-theoretic analysis were quite surprising: unlike traditional communication, where the number of messages grows exponentially, they showed that in identification, the message set grows doubly exponentially. Since then, the concept of identification has found its way into practical applications, particularly within research projects. The most prominent applications have emerged in alarm and control systems. Another promising direction is the use of identification within the context of molecular communication. Initial studies focused on deterministic identification, but recent work has extended to include randomized identification as well. This tutorial will begin with an introduction to the theory of message identification and conclude with a discussion of its applications in the context of molecular communication.
BIO: Christian Deppe received his Dipl.-Math. degree in mathematics from the University of Bielefeld in 1996 and his Dr.-math. degree, also from the University of Bielefeld, in 1998. He then worked there until 2010 as a research associate and assistant at the Faculty of Mathematics, Bielefeld. In 2011, he took over the management of the project "Safety and Robustness of the Quantum Repeater" from the Federal Ministry of Education and Research at the Faculty of Mathematics, Bielefeld University, for two years. In 2014, Christian Deppe was funded by a DFG project at the Chair of Theoretical Information Technology, Technical University of Munich. At the Friedrich Schiller University in Jena, Christian Deppe took up a temporary professorship at the Faculty of Mathematics and Computer Science in 2015. Until 2023, he worked for six years at the Chair of Communications Engineering at the Technical University of Munich and since January 2024 has taken on new tasks at the Institute of Communications Engineering at the TU Braunschweig. He is project leader of several projects funded by the BMBF and the DFG.
