Bio

Ruben is a Senior Innovation Engineer and Technical Expert in Mobile Networking in the Strategy & Innovation Group of Swisscom where he works on product innovation and development. From 2008 to 2012, he was a Senior Research Scientist in the Internet Network Architecture group of (Deutsche) Telekom Innovation Laboratories in Berlin, Germany.

He earned his PhD and MSc in Communication Systems from the School of Computer and Communication Systems, EPFL in 2008 and 2003, respectively.

In 2001, he interned as a software engineer for Fast Forward Networks in San Francisco, California. From August 2002 to March 2003, he carried out his Master thesis at the Department of Electrical Engineering, Indian Institute of Technology, Delhi (IITD) in India. He was then a PhD student at LCA from 2003 to 2008, under the supervision of Professor Jean-Yves Le Boudec. He was awarded a best student paper award at the 2005 IEEE International Conference on Ultra-Wideband (ICU 2005) and a best demo award at the 2006 MICS Scientific Conference for the demo "An Impulse-Radio Ultra-Wide Band Testbed with Interference".

Research

I'm broadly intested in networked systems, with an emphasis on wireless networks. In general I enjoy designing, modeling and running performance evaluations of wireless systems. Recently, I've spent most of my time working on home networking and cellular access systems. When it comes to performance evaluation, I tend to use whatever tool or technique is the most appropriate, either via simulation, analytical techniques or testbed deployments.

Ongoing Projects

  • Odin: an experimental SDN framework for enterprise wireless networks ( Lalith's blog post on Odin).
  • SAW: distributed spectrum assignements for WLANs. This is a collaboration with Julien Herzen and Patrick Thiran at EPFL.
  • Interference management for femtocell networks. Collaboration with Raymond Knopp at Eurecom, more details soon.

Older Projects

  • Berlin Open Wireless Lab (BOWL): The BOWL project operates a campus-wide, close to production, wireless research network for experimentation in a realistic environment. It is a unique infrastructure since (1) live traffic can be safely transported over a research network running experimental protocols, (2) its reconfiguration capabilities allow researchers to use the network with different operational modes (for instance, an infrastructure network or a mesh network), and (3) researchers can easily design and evaluate protocols at the network layer and above.
  • Enhance & Explore: an adaptive algorithm to maximize the utility of wireless networks. This is a really cool algorithm that can maximize the utility of a wireless network, without the need to explicitely characterize the capacity. This is a collaboration with Adel Aziz, Julien Herzen and Patrick Thiran at EPFL.
  • OFELIA: OpenFlow in Europe - linking infrastructure and applications
  • ns-3 network simulator: testbed in a simulator | ns-3-click (GSOC 2010 mentorship - summary) | ns-3 Minstrel integration (GSOC 2009 mentorship - summary)
  • Ultra-Wide Band (UWB) Networking
