9. Sponsored by the National Science Foundation 9 November 3, 2010 ParkNet with GENI GENI has proven valuable by –Allowing cost effective experimentation with delay-tolerant data collection protocols on Wimax/4G cellular networks –Battle-hardened hardware and relevant domain knowledge –Providing tools for executing and orchestrating experiments across a set of mobile nodes –Tools to deploy and keep alive long running experiments (almost hands-off) –Monitoring & instrumentation plane to obtain and manage large amounts of measurements (data) Results to date Science: MobiSys best paper award Outreach: MIT Tech Review, CBC Online, etc We look forward to experimenting at more WiMAX sites and with more vehicles as GENI grows
