I joined the working group Computer Systems & Telematics (CST) at the Institute of Computer Science, Freie Universität Berlin in January 2006, after receiving my M.Sc. in 2005 and my B.Sc. in 2003 from the same university. I completed my Ph.D. in September 2010.

Research Activities
My research is focused on wireless ad hoc networking. I'm particularly interested in the topics of service placement, distributed event detection in Wireless Sensor Networks (WSNs), and accuracy of wireless network simulations.
Projects
| SPi | Taking an application-centric view on ad hoc networks, cooperation between devices is structured by application-level clients and servers, i.e., certain nodes requesting services provided by other nodes. This gives rise to the question in how far the performance of the network can be increased by intelligently selecting which nodes are to host a particular service. The process of identifying the appropriate nodes to act as servers is referred to as service placement and invesigated using our SPi service placement framework. More information is available on the SPi homepage. |
| AVS-Extrem / Fence Monitoring |
The AVS-Extrem (formerly Fence Monitoring) project is a use case for Wireless Sensor Networks (WSNs) focused on collaborative, in-network data processing. The goal is to develop a distributed event detection algorithm that can reliably report security relevant incidents (e.g. a person climbing over a fence) to a base station. The vision is that through cooperation of many sensor nodes the accuracy of event detection can be greatly improved, while at the same time saving energy by reducing multi-hop communication with the base station. More information about the AVS-Extrem project is available on the AVS-Extrem homepage. |
| ScatterWeb on ns-2 | In order to ease
development and for later simulation purposes, we have decided to port the
ScatterWeb software to the
ns-2 network simulator.
Implemented as a layer of glue code, it allows for applications written
against the ScatterWeb API to be run without changes on both the simulator
and the real-world sensor nodes. More information about ScatterWeb on ns-2 is
available on the
ScatterWeb on ns-2 homepage. |
| FACTS | FACTS is a middleware architecture for wireless sensor networks (WSN). It is build around an event and data centric programming paradigm inspired by expert systems. Sensor readings and system information are both represented as facts that are processed by rules. More information about FACTS is available on the FACTS homepage. |
