Online Learning Models for Content Popularity Prediction in Wireless Edge Caching

Abstract: Caching popular contents in advance is an important technique to achieve the low latency requirement and to reduce the backhaul costs in future wireless communications. Considering a network with base stations distributed as a Poisson point process (PPP), optimal content placement caching probabilities are derived for known popularity profile, which is unknown in practice. In this paper, online prediction (OP) and online learning (OL) methods are presented based on popularity prediction model (PPM) and Grassma… Show more

“…In addition, to understand the benefits of multipoint multicast caching, we compare to single point caching. In [6], [24], each user is served by its nearest caching BS, and bandwidth is not allocated among files. Hence, for any file request, all BSs which cache that file, except the nearest BS, interfere with the desired signal.…”

“…In this case each BS can simultaneously transmit several files in disjoint radio resources, so L can be greater than one. Using the outage probability expression in [24], the overall outage probability and its corresponding optimization problem can be formulated and used to obtain the optimum cache policy.…”

“…Content update statistics evolved to become a fundamental component in the design and study of any communication network where caching and prefetching play a central role, such as content delivery networks (CDNs) and Information-centric networks (ICNs) [3][4][5], 5G networks [6][7][8][9], and wireless networks [10]. Indeed, accurate estimation of inter-update distribution is an important issue.…”
