From Self-Organizing Systems Group

Björn Saballus is PhD student [Wissenschaftlicher Mitarbeiter] in the Self-Organizing Systems Group of Thomas Fuhrmann since 2006. He started to study "General Engineering Science" at the Technical University of Hamburg-Harburg (TUHH) where he received his Bachelor Degree. Afterwards he continued to study Electrical Engineering with a major in Computer Engineering at the TUHH where he received his Dipl.-Ing. in Electrical Engineering.

Before changing to TUM in 2009, Björn was already a team member of Thomas Fuhrmann in Karlsruhe at the IBDS.

Since 2007 Björn is a member of the CeDoSIA/TUM Graduate School program of the TUM.

Research interests

I am interested in the following research questions: My main topic is to investigate self-organization mechanisms used in common peer-to-peer network scenarios and apply them to clusters of multi-core processors.

My current work is an enhancement of the scalable source routing (SSR) protocol, a distributed hash table (DHT)-inspired routing protocol. This protocol shall be used to address globally accessible objects (GAO). It can ensure that a processor core can access a GAO after it has been migrated to another node. It does so without the need for any centralized entities. Besides the work on SSR and GAOs, I plan to investigate the use of object replica to deal with node failures.
