Modern day's User Equipments (UEs) are equipped with rich resources which encourage them to be used for more sophisticated applications. On the other hand, with these equipments in hand, users demand for high-quality video on the move is increasing day-by-day. Moreover, Information/Content Centric Networking (ICN/CCN) has changed the network dynamics by getting the desired contents regardless of the location. Unused memory in UEs can be used to cache the contents and provide it to the other nearby users on demand. In this paper, we propose to provide the requested video to users from other users cache, using D2D link, if it is present there. Our objective is to reduce the download delay for the users' requested video. We formulate the problem as a matching game in which the resources are assigned to the users in the uplink period. The UEs select the content node for D2D communication and the suitable channel. We have evaluated the proposed mechanism by implementing it in Matlab and have compared it with greedy approach and no D2D communication scheme. The experimental results show the effectiveness of our proposed mechanism.
