【Abstract】Virtual reality (VR) streaming is becoming a popular mobile application that requires ultralow latency and active participation of devices. Meanwhile, blockchain is a promising paradigm to decentralize the traditional ledger of a single trusted entity. In this article, a deep deterministic policy gradient (DDPG)-based scheme is proposed to tackle the joint resource allocation and replica selection challenge of VR streaming in blockchain-enabled fog radio access networks (F-RANs). The proposed scheme balances the load on VR streaming and blockchain maintenance and fully exploits the edge caching and computing resources on fog-based access points (F-APs). Thus, less energy is consumed compared with other learning schemes based on extensive simulations.
