Motivation: Cruising for Parking
• US: $78 billion cost of congestion (time & gasoline)
• Cruising for Parking:• Brooklyn: 45%• Soho: 28%
• LA – Westwood village (small business district):• 730 tons CO2• 47,000 gal gasoline• 950,000 VMT• Source: D. Shoup

What if … Real-time Parking Availability Statistics?
• Drivers: Guide drivers to regions with available parking
• Cities:– Setting prices– maximum stays– where to install parking
meters• More informed travel
decisions: public transit vs carpool vs car

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
