Energy and Latency Efficient Caching in Mobile Edge Networks: Survey, Solutions, and Challenges

Future wireless networks provide research challenges with many fold increase of smart devices and the exponential growth in mobile data traffic. The advent highly computational real-time applications cause huge expansion traffic volume. emerging need to bring closer users minimizing off macrocell base station introduces use caches at edge networks. Storing most popular files (MENs) user terminals (UTs) small stations is a promising approach that face data-rich Caching UT allows obtain requested contents directly from its nearby UTs through device-to-device (D2D) communication. In this survey article, solutions for computing caching terms energy latency are presented. MENs comparisons between different techniques An illustration cache development apply intelligent learning specific domain their design We summarize system MENs. Finally, some future directions discussed placement access delivery
