More objects are becoming embedded with sensors and gaining the ability to communicate. The resulting information networks promise to create new business models, improve business processes, and reduce costs and risks.

Wireless sensor networks on the street know which parking spots are free and will direct you straight to a free space. Then the city uses that real-time information for dynamic meter pricing, discouraging driving when car traffic is too high. San Francisco is already trying the idea. If it works, it will be good for motorists, for the city, and for the environment.
