As smart phones are getting prevalent in mobile industry, they are expected to replace application-specific sensors. Wireless connectivity, GPS-based localization capability, and OS can provide a platform for general-purpose sensors. Furthermore, smart phones carried by users add mobility to static sensors, covering a dynamic range.
To stimulate user participation, we design and evaluate novel auction-based dynamic pricing incentive mechanisms where users can sell their sensing data to a service provider with users’ claimed bid prices. The proposed incentive mechanism should focus on minimizing and stabilizing the incentive cost while maintaining an adequate level of participants by preventing users from dropping out of participatory sensing applications.
