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
