SPCN: Providing smart support for proactive caching in mobile scenario

摘要

In recent years, the ever-growing number of mobile users and demands for mobile services exert great pressure on wireless content transmission. It is still a challenge to provide high-quality service in mobile scenario. To improve the quality of mobile service, proactive caching is proposed to push popular and requested service content to the nearest base stations or access points from mobile users through mobility prediction and content prefteching and caching. Despite a lot of proactive caching algorithms have been proposed, there is few research has been done to design and establish a network architecture which is capable of providing smart and native support for proactive caching. Therefore, in this paper, a Smart Proactive Caching Network (SPCN) is proposed to fill the gap. The architecture and working procedure of SPCN is presented and network model is established. The performance is also evaluated.
