A Signaling-based Incentive Mechanism for Device-to-Device Content Sharing in Cellular Networks

摘要

In this letter, we model the Device-to-device (D2D)udcontent sharing problem as a labor market where the base stationud(BS) acts as the principal and content providers serve as agents.udA signaling-based content-sharing incentive (SCSI) mechanism isuddesigned to encourage candidate content providers to participateudin content sharing, and the optimal strategy for each contentudprovider is derived to maximize their utility (monetary profit)udwhile guaranteeing a non-negative utility for the BS. Simulationudresults show that the proposed SCSI mechanism can increase theudcontent provider’s utility and participating enthusiasm in D2Dudcontent sharing.
