Title: SYSTEM AND METHOD FOR CORRELATION-AWARE CACHE-AIDED CODED MULTICAST (CA-CACM)
Abstract:
Requests are received from destination devices for files of a plurality of data files, each of the requested files including at least one file-packet. A conflict graph is built using popularity information and a joint probability distribution of the plurality of date files. The conflict graph is colored. A coded multicast is computed using the colored conflict graph. A corresponding unicast refinement is computed using the colored conflict graph and the joint probability distribution of the plurality of data files. The coded multicast and the corresponding unicast is concatenated. The requested files are transmitted to respective destination devices of the plurality of destination devices.
