  2. What is CRAWDAD? Community Resource for Archiving Wireless Data At Dartmouth • Co-led by David Kotz and Tristan Henderson • Hosted by the Center for Mobile Computing at Dartmouth College • Funded by US National Science Foundation • Archive • Wireless-network traces • Tools for trace collection • HOWTO documents in wiki • Support for the research community • Event calendar • Bibliography • Specialist groups (MANET, Education) • Annual Workshop (free!)

  3. Why CRAWDAD? • Get access to real wireless data • Understand real network usage and identify the real problem • Evaluate solutions better than simulation • Data is hard to collect – leverage effort to benefit all • Make our field more scientific • Reusing/sharing data is good practice • More appreciation (citations!) if you share data • Learn from others’ experience • Learn in more ways than from a paper

  4. CRAWDAD is growing! (as of March 2007) • 541 users from 327 institutions around the world • 23 data sets • 802.11, MANET, VANET, Sensor-net, DTN, mobility • 12 tools • collect, process, sanitize, analyze, … • 70 papers • Staff: • full-time programmer plus 2 undergrads • contact: crawdad@cs.dartmouth.edu

  5. CRAWDAD for GENI • CRAWDAD as archive for GENI wireless data • Provide traces from production networks to drive experiments on GENI testbeds • Archive measurements from testbed experiments • Indexing,annotating, and sanitizing for sharing • Why? • CRAWDAD is already the “go-to” site for wireless • Improve the scientific process through data sharing • Encourage repeatability • Encourage new analysis of prior work • Encourage proper comparison with prior work • Encourage production of common tools and formats

  6. CRAWDAD “At a minimum, we in the CRAWDAD project would be happy to become the official data-sharing site for wireless experimental data exported from GENI experiments. We may also be interested in expanding our services to link more closely into the GENI's archival system itself, to support wireless measurement and experimental-data storage, to ease the annotation and export of experimental data into public archives.” – David Kotz and Tristan Henderson
