A proactive caching approach in 5G networks

Abstract

One of the key challenges of emerging networking technologies e.g. 5G, is handling a large number of user requests. Network caching is a well-experienced approach to addressing this challenge, through which frequently requested files are cached at the network edge to reduce the latency and traffic load of the network. Here, a Multilevel Proactive Caching (MPC) approach is suggested, which creatively exploits the effect of time on the file fame, denoted as a parameter called "boost". Boost as well as some other parameters like fame and conent volume are utilized to determine an individual parameter called precedence. The results indicate that the suggested approach, significantly enhances the cache hit ratio, backhaul load and file access latency of the network.
