Surveillance service on the open mobile cloud

Mobile Vehicular Clouds are emerging as systems architectures suitable to provide services to both drivers and external customers. The paper describes a Pics-on-Wheel architecture and prototype implementation based on the idea of open mobile cloud. A simulation study based on San Francisco taxi cab traces shows that the Pics-on-Wheel service yields latencies in the order of 5 minutes in well frequented areas even with a modest number of vehicles. The results also show that by introducing incentives for active driver participation, even minimal detours noticeably reduce latencies.
