Dynamic content updates in heterogeneous wireless networks
Content storage at the network edge is a promising solution to mitigate the
excessive traffic load due to on-demand streaming applications as well as to
reduce the streaming delay. To this end, cache-enabled cellular architectures
can be utilized to increase the provided quality-of-service (QoS) and to reduce
the network cost. However, there are certain issues to be considered in the
design of the content storage strategy such that the contents should be
refreshed in order to responds user`s expectations. Using a frequent cache
refreshment strategy the ratio of satisfied users can be increased at an
increasing network cost. In this paper, we introduce a cache refreshment
strategy via leveraging learning techniques so that users' tolerance to the age
of content is learned and the content is refreshed accordingly
