On the Stable Throughput of Cooperative Cognitive Radio Networks with Finite Relaying Buffer
Adel M. Elmahdy, Amr El-Keyi, Tamer ElBatt +1
In this paper, we study the problem of cooperative communications in cognitive radio systems where the secondary user has limited relaying room for the overheard primary packets. M…
A Probabilistic MAC for Cognitive Radio Systems with Energy Harvesting Nodes
Ramy E. Ali, Fadel F. Digham, Karim G. Seddik +3
In this paper, we consider a cognitive radio (CR) system where the secondary user (SU) harvests energy from both the nature resources and the primary user (PU) radio frequency(RF)…
Maximum Throughput of a Secondary User Cooperating with an Energy-Aware Primary User
Ahmed El Shafie, Ahmed Sultan, Tamer Khattab
This paper proposes a cooperation protocol between a secondary user (SU) and a primary user (PU) which dedicates a free frequency subband for the SU if cooperation results in energ…
Probabilistic Band-Splitting for a Buffered Cooperative Cognitive Terminal
Ahmed El Shafie, Ahmed Sultan, Tamer Khattab
In this paper, we propose a cognitive protocol that involves cooperation between the primary and secondary users. In addition to its own queue, the secondary user (SU) has a queue…
