Abstract:
Many problems of distributed computing can be reduced to monitoring the value of a function defined over a set of distributed data streams with respect to a threshold. Precisely, given an arbitrary (not necessarily linear) function, a threshold, and a set of distributed data streams out of which the input of the function is determined, we want to detect the event of the function value crossing the threshold. The state-of-the-art approach for function monitoring relies on geometric insights to decompose the monitoring process to a set of local constraints for each stream. In this talk, I will present this approach and summarize our ongoing work based on it.

Short Bio:
Odysseas Papapetrou is currently a postdoctoral researcher at the Technical University of Crete, working on P2P networks and distributed streams. He received his PhD in Computer Science from University of Hannover, while collaborating with the L3S Research Center. He also obtained an M.Sc. from Saarland University in Germany, supported by an IMPRS scholarship, and a B.Sc. and M.Sc. from the University of Cyprus.
