Abstract EN
Content caching at the base station of the Radio Access Network (RAN) is a way to reduce backhaul transmission and improve the quality of experience.
So it is crucial to manage such massive microcaches to store the contents in a coordinated manner, in order to increase the overall mobile network capacity to support more number of requests.
We achieve this goal in this paper with a novel caching scheme, which reduces the repeating traffic by request filtration and asynchronous multicast in a RAN.
Request filtration can make the best use of the limited bandwidth and in turn ensure the good performance of the coordinated caching.
Moreover, the storage at the mobile devices is also considered to be used to further reduce the backhaul traffic and improve the users’ experience.
In addition, we drive the optimal cache division in this paper with the aim of reducing the average latency user perceived.
The simulation results show that the proposed scheme outperforms existing algorithms.
