SUMMARY:Competitive Caching of Contents in 5G Edge Cloud Networks
DESCRIPTION:The surge of mobile data traffic forces network operators to
 cope with capacity shortage. The deployment of small cells in 5G networks
 is meant to increase radio access capacity. Mobile edge computing
 technologies\, in turn\, can be used in order to manage dedicated cache
 space memory inside the radio access network\, thus reducing latency and
 backhaul traffic. Mobile network operators will be able to provision
 content providers with new caching services to enhance the quality of
 experience of their customers on the move. Cache memory in the mobile edge
 network will become a shared resource.We study a competitive caching scheme
 where contents are stored at given price set by the mobile network
 operator. We first formulate a resource allocation problem for a tagged
 content provider seeking to minimize the expected missed cache rate. The
 optimal caching policy is derived accounting for popularity and
 availability of contents\, the spatial distribution of small cells\, and
 the caching strategies of competing content providers. It is showed to
 induce a specific order on contents to be cached based on their popularity
 and availability.Next\, we study a game among content providers in the form
 of a generalized Kelly mechanism with bounded strategy sets and
 heterogeneous players. Existence and uniqueness of the Nash equilibrium are
 proved. Numerical results validate and characterize the performance of the
 system and the convergence to the Nash equilibrium.
