Abstract
This paper studies the cellular traffic offloading in a content sharing network (CSN) where some mobile devices functioned as caching contributors can provide the nearby devices with popular contents on demand via D2D communication links. In consideration of the inherent selfishness of mobile users, the main challenge turns to be how to urge the device to maximize content sharing actively acting as the contributory caching device (CCD) via D2D link. To facilitate content sharing, a contribution-based incentive mechanism is introduced to encourage the CCDs. We formulate selectively caching as a matching problem and put forward a caching strategy to determine whether to cache some particular contents using Kuhn-Munkres algorithm. And the performances are validated by the numerical results.
