Channel-aware caching-aided coded multicast

A computer-implemented method for transmitting data from a network element interconnected with a plurality of receiver devices via a wireless Content Delivery Network (CDN), the method comprising:

• receiving a request from the plurality of receiver devices for a data segment over the wireless CDN;
• computing a number of descriptors of the data segment scheduled to be delivered to each of the plurality of receiver devices for the requested data segment, the number of descriptors being determined for each of the plurality of receiver devices based on channel conditions between the network element and the plurality of receiver devices;
• cluster a set of descriptors for each of the plurality of receiver devices into a minimum number of Generalized Independent Sets (GISs) based on the computed number of descriptors and the channel conditions between the network element and each of the plurality of receiver devices;
• generate channel codewords encoding the clustered descriptors for each of the plurality of receiver devices using the minimum number of GISs and based on the channel conditions;
• generate a multicast codeword from the generated channel codewords for transmission to each of the plurality of receiver devices;
• and
• transmit the multicast codeword to each of the plurality of receiver devices in response to the received request in order to allow each of the plurality of receiver devices to decode the multicast codeword into the requested data segment.
