Past Projects

• Analyzing BitTorrent with the Bro IDS
  

  In the context of a student project I wrote a BitTorrent protocol analyzer for the Bro Network Intrusion Detection System, which became part of the official Bro release. Bro is being developed by Vern Paxson at Lawrence Berkeley National Laboratory and the International Computer Science Institute.

• Mesh routing with the Click Modular Router
  

  As a part of my Diploma thesis I implemented the Simple Opportunistic Adaptive Routing Protocol (SOAR) for wireless mesh networks as an element for the Click Modular Router. My implementation is based on the IEEE WiMesh Workshop paper by Eric Rozner et al., September 2006. There is a revised publication on SOAR available.
