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…
Effective Capacity of Cognitive Radio Links: Accessing Primary Feedback Erroneously
M. Majid Butt, Ahmed Anwar, Amr Mohamed +1
We study the performance of a cognitive system modeled by one secondary and one primary link and operating under statistical quality of service (QoS) delay constraints. We analyze…
Cognitive Radio Networks with Probabilistic Relaying: Stable Throughput and Delay Tradeoffs
Mahmoud Ashour, Amr A. El-Sherif, Tamer ElBatt +1
In this paper, we study and analyze fundamental throughput and delay tradeoffs in cooperative multiple access for cognitive radio systems. We focus on the class of randomized coope…
Interference-Based Optimal Power-Efficient Access Scheme for Cognitive Radio Networks
Ahmed H. Anwar, Ahmed El Shafie, Amr Mohamed +2
In this paper, we propose a new optimization-based access strategy of multipacket reception (MPR) channel for multiple secondary users (SUs) accessing the primary user (PU) spectru…
