It is a great pleasure for us to announce a talk from Prof. Kenji Leibnitz from the University of Osaka, Japan.

Abstract of the Talk

Biological systems have the inherent ability to self-organize and self-adapt when facing changes in the environmental conditions. Mostly, self-organization in nature is achieved through positive and negative feedback control and local interactions among individuals, as well as by exploiting the ambient fluctuations and noise within the system. Due to such mechanisms, biological systems exhibit a high robustness towards failure and high adaptability to changes in the environment, however, at the potential cost of a slower adaptation speed. Recently, several concepts inspired by biological phenomena have been successfully adopted in the field of communication networks, for example routing protocols based on the foraging behavior of ants. With the vastly growing efforts towards ambient and future generation wireless networks such approaches are expected to gain even more in importance. In this presentation, we will discuss the fundamental properties and concepts of biological self-organization, as well as provide examples of how such approaches can be successfully applied to information and communication networks to improve their robustness and resilience. The presented work is obtained from studies within the frameworks of the "Yuragi Project" (http://www.yuragi.osaka-u.ac.jp/) and the "Center of Excellence for Founding Ambient Information Society Infrastructure" (http://www.ist.osaka-u.ac.jp/GlobalCOE) at Osaka University, Japan, which are both highly interdisciplinary projects involving researchers from diverse areas, such as bio-engineering, nano-technology, robotics, information science, as well as collaborators from industry.


Kenji Leibnitz studied information science at the University of Würzburg in Germany where he obtained his master's and PhD degrees. In 2004, he joined the Advanced Network Architecture Laboratory at the Graduate School of Information Science and Technology of Osaka University, where he is currently a Specially Appointed Associate Professor, working on the application of biologically-inspired methods to information networks within the Yuragi-project.
