Diamond Message Set Groupcasting: From an Inner Bound for the DM Broadcast Channel to the Capacity Region of the Combination Network
Mohamed Salman, Mahesh K. Varanasi
Multiple groupcasting over the broadcast channel (BC) is studied. In particular, an inner bound is obtained for the -receiver discrete memoryless (DM) BC for the diamond message…
Capacity Results for the K-User Broadcast Channel with Two Nested Multicast Messages
Mohamed Salman, Mahesh K. Varanasi
The K-user discrete memoryless (DM) broadcast channel (BC) with two nested multicast messages is studied in which one common message is to be multicast to all receivers and the sec…
The K-User DM Broadcast Channel with Two Groupcast Messages: Achievable Rate Regions and the Combination Network as a Case Study
Mohamed Salman, Mahesh K. Varanasi
A novel class of achievable rate regions is obtained for the K-receiver broadcast channel with two groupcast messages. The associated achievability schemes are parameterized by an…
Sensing/Decision-Based Cooperative Relaying Schemes With Multi-Access Transmission: Stability Region And Average Delay Characterization
Mohamed Salman, Amr El-Keyi, Mohammed Nafie +1
We consider a cooperative relaying system which consists of a number of source terminals, one shared relay, and a common destination with multi-packet reception (MPR) capability. I…
