Optimizing MDS Codes for Caching at the Edge

  title={Optimizing MDS Codes for Caching at the Edge},
  author={Valerio Bioglio and Frederic Gabry and Ingmar Land},
  journal={2015 IEEE Global Communications Conference (GLOBECOM)},
In this paper we investigate the problem of optimal MDS-encoded cache placement at the wireless edge to minimize the backhaul rate in heterogeneous networks. We derive the backhaul rate performance of any caching scheme based on file splitting and MDS encoding and we formulate the optimal caching scheme as a convex optimization problem. We then thoroughly investigate the performance of this optimal scheme for an important heterogeneous network scenario. We compare it to several other caching… CONTINUE READING
