Wireless edge caching networks: turning storage into bandwidth

Abstract: In wireless networks, edge nodes are the base stations who are directly connected to users. In the recent years, the statistics have revealed the cause of backhaul and fronthaul congestion is due to the users’ repetitive demands of the popular (e.g. multimedia) content. Moreover, the data limits provided by the network operators are not enough for sustainable data and its rates required for a multimedia content. Therefore, next generation networks are being evolved based on edge caching, where popular contents are placed in edge nodes for scalable and quick access to a large number of users, and the cache storage is updated regularly.

Further, since popularity of different contents changes over time, a dynamic caching scheme based on assessing future and present popularities are preferable. In this context, the machine learning approaches are investigated. However, due to huge number of contents over the internet, we present scalable online learning solutions, which includes reinforcement learning and its function approximated learning approaches as well.
