5G Wireless Backhaul Networks: Challenges and Research Advance
Xiaohu Ge, H. Cheng, M. Guizani +1
5G networks are expected to achieve gigabit-level throughput in future cellular networks. However, it is a great challenge to treat 5G wireless backhaul traffic in an effective way…
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…
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…
Generalized Area Spectral Efficiency: An Effective Performance Metric for Green Wireless Communications
Lei Zhang, Hong-Chuan Yang, Mazen O. Hasna
Area spectral efficiency (ASE) was introduced as a metric to quantify the spectral utilization efficiency of cellular systems. Unlike other performance metrics, ASE takes into acco…
