Adapting Data Popularity in Mobility-Based Proactive Caching Decisions for Heterogeneous Wireless Networks
Journal Title: EAI Endorsed Transactions on Cloud Systems - Year 2016, Vol 2, Issue 7
Abstract
The current paper presents extensions to a distributed user mobility-based proactive caching scheme that supports individual users’ requests, and a brief discussion of the benefits from exploiting user-centric features. The approach applies to Heterogeneous Wireless Networks (HWNs) for offloading traffic volumes to small cells and for reducing delay for specific categories of mobile users and mobile application scenarios through Efficient Proactive Caching (EPC) decisions at small cells. The approach is designed to support mobile users’ requests for content not treated by popularity-based caching. Here, we discuss how proactive caching decisions can jointly utilize individual user mobility and data popularity to enhance the benefits of cache decisions for individuals to a broader set of mobiles requesting the same data.
