Co-Operative and Hybrid Replacement Caching for Multi-Access Mobile Edge Computing

Abstract

Multi-Access Mobile Edge Computing (MEC) is proclaimed as a key technology for reducing service processing delays in 5G networks. Caching on MEC will decrease service latency and improve data access by allowing direct content delivery through the edge without fetching content from the remote server, Caching on MEC is also deemed as an effective approach that guarantees more reachability due to proximity to end-users. This paper proposes a novel hybrid content caching replacement algorithm in MEC to increase its caching efficiency where future request references are predicted using a polynomial fit algorithm along with Lagrange interpolation. Additionally, a distributed co-operative caching algorithm to improve data access within MECs. Experimental results have shown that the proposed scheme obtains more cache hits and lesser average CPU utilization due to its selective caching approach when compared with existing traditional cache replacement algorithms.
