CRAWDAD is the Community Resource for Archiving Wireless Data At Dartmouth, a wireless network data resource for the research community. This archive has the capacity to store wireless trace data from many contributing locations, and staff to develop better tools for collecting, anonymizing, and analyzing the data. We work with community leaders to ensure that the archive meets the needs of the research community.
Please join us! You can download data or tools, contribute your data (why?), or simply join our crawdad-news mailing list. You can also follow us on Twitter, or take a look at the world map of CRAWDAD users.
CRAWDAD is sponsored by ACM SIGMOBILE, Intel Corporation, and the National Science Foundation.
