A cooperative Q-learning approach for distributed resource allocation in multi-user femtocell networks
Saad H.; Mohamed A.; El Batt T. ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)This paper studies distributed interference management for femtocells that share the same frequency band with macrocells. We propose a multi-agent learning technique based on distributed Q-learning, called subcarrier-based ... -
Cognitive Radio Networks with Probabilistic Relaying: Stable Throughput and Delay Tradeoffs
Ashour M.; El-Sherif A.A.; ElBatt T.; Mohamed A. ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Article)This paper studies fundamental throughput and delay tradeoffs in cognitive radio systems with cooperative secondary users. We focus on randomized cooperative policies, whereby the secondary user (SU) serves either its own ... -
Cooperative Q-learning techniques for distributed online power allocation in femtocell networks
Saad, H.; Mohamed, A.; ElBatt, T. ( John Wiley & Sons, Ltd. , 2015 , Article)In this paper, we address the problem of distributed interference management of femtocells that share the same frequency band with macrocells using distributed multi-agent Q-learning. We formulate and solve two problems ... -
Effective capacity of cognitive radio links: Accessing primary feedback erroneously
Butt M.M.; Anwar A.H.; Mohamed A.; El Batt T. ( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference Paper)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 the effective capacity (EC) to quantify ...
