Fundamental Limits of Decentralized Caching in Fog-RANs with Wireless Fronthaul [PDF]

2018 IEEE International Symposium on Information Theory (ISIT), 2018
This paper aims to characterize the synergy of distributed caching and wireless fronthaul in a fog radio access network (Fog-RAN) where all edge nodes (ENs) and user equipments (UEs) have a local cache and store contents independently at random. The network operates in two phases, a file-splitting based decentralized cache placement phase and a ...
