Outband D2D Communication for Layered Video Delivery in ICN Enabled Cellular Network

D2D communication has brought a paradigm shift to cellular networks. Video streaming is always been a bandwidth killer for the networks. With high speed internet connectivity through advanced cellular networks, mobile users demand for watching high quality video is also increasing. In this paper we propose a model for offloading layered video streaming in cellular network with Information Centric Networking concept using outband D2D communication. The proposed mechanism makes D2D pairs on the basis of mutual benefits or benefits from the service provider. In case both the users watch the same video (like time shifted TV or live sports events etc.), they cooperatively schedule video offloading and sharing via outband D2D link to get higher quality video. In the analysis we have shown that our proposed mechanism increases network coverage throughput and hence QoE.
