Contents Caching Scheme in D2D Caching Systems when Incentives are Provided to Users

Abstract

In wireless networks with coverage and backhaul issues, install content caches on devices and use device-to-device (D2D) communication technology to deal with increased mobile traffic and content on other devices D2D cache system technology that provides is under active research. In this paper, a special device that can supply content to other devices that have a largecapacity cache is called a helper, in order to increase the hit ratio of the content stored in the helper. We are considering a solution of providing rewards to users. We proposed that what content needs to be saved and what effects can be obtained through compensation to the user.
