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

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
Sponsored by the National Science Foundation
• 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
