Enhancing the Users' Experience in a Discontinuous Coverage Architecture

The progress of wireless communication technologies allows the implementation of high rate applications. Users want to use their mobile devices, equipped with a wireless interface, to watch videos and capture images and video clips. Indeed, these high rate applications can quickly consume the available radio bandwidth. In this context, classical mobile networks provide a throughput which is expensive in terms of costs and is not, in most cases, sufficient to serve a large number of users. The purpose of this work is to study the performance of the discontinuous coverage architecture based on caching within centralized entities. Mainly, a popularity system is proposed to enhance the users' quality of experience in the up-link.
