Abstract: In radio access networks, mobile devices access internet content through base stations, which are connected to the internet via gateway routers. A number of studies have been carried out to improve the performance of internet access by mobile hosts. Among these, caching of popular web documents at locations close to the mobile clients is an effective method. The benefits of caching data in the core network of mobile carrier have been investigated in the literature. There has been some research in caching of videos for online video sites like YouTube, which aims at improving the performance of the mobile internet access networks. Caching of Most Popular Videos (MPV) together with LRU (Least Recently Used) - replacing the least recently used video when cache is full- algorithm is an efficient method for large sized caches which are only possible for internet content delivery networks. Caching algorithms for ad-hoc networks has also been developed. These are not applicable for radio access networks. This paper investigates the effectiveness of placing caches at base stations in cellular networks and considers the UPP (User Preference Profile) of each cell-site for caching of videos.
