It also uses this process to proactively suggest to nodes located lower in the network hierarchy the caching of relevant content. The state-of-the-art analysis reveals Nuoxus as the first model to explore the nodes&#8217; request history to perform proactive caching without relying on external and centralized components. Furthermore, the developed proof-of-concept shows significant gains when compared to other caching strategies.<\/p>\n<p><a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S0167739X18302449\">Future Generation Computer Systems<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>One of the most recently proposed 5G architectures, Fog Radio Access Network or F-RAN, has the same cloud computing-based approach of C-RANs while giving additional storage and processing power to the edge nodes so that they can address network activities.
