Invited by the High Performance Network Laboratory of IACAS, Prof. XUE Guoliang from the Arizona State University gave a lecture on May. 15, introducing his published paper in MobiCom(the annual international conference on mobile computing and networking) 2012. The title of the paper is "Crowdsourcing to smartphones: incentive mechanism design for mobile phone sensing”.

In XUE’s lecture, he presented his design of incentive mechanisms for mobile phone sensing for smartphone users to participate in crowdsourcing.

XUE introduced two system models of the mechanisms: the platform-centric model where the platform provides a reward shared by participating users, and the user-centric model where users have more control over the payment they will receive.

For the platform-centric model, an incentive mechanism using a Stackelberg game, where the platform is the leader while the users are the followers is designed. About the user-centric model, an auction-based incentive mechanism is designed, which is computationally efficient, individually rational, profitable, and truthful.

Smartphones are lightweight and provide extensive communication, computation, and sensing capabilities. These features make smartphones ideal for crowdsourcing, which is a new computing paradigm for human centric computing with collective intelligence.
