Cognitive Radio Networks with Probabilistic Relaying: Stable Throughput and Delay Tradeoffs
( 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 access in cognitive radio networks: Stable throughput and delay tradeoffs
( IEEE , 2014 , Conference Paper)In this paper, we study and analyze fundamental throughput-delay tradeoffs in cooperative multiple access for cognitive radio systems. We focus on the class of randomized cooperative policies, whereby the secondary user ... -
Energy-Aware Cooperative Wireless Networks with Multiple Cognitive Users
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)In this paper, we study and analyze cooperative cognitive radio networks with arbitrary number of secondary users (SUs). Each SU is considered a prospective relay for the primary user (PU) besides having its own data ... -
On the power efficiency for cognitive radio networks with multiple relays
( IEEE , 2014 , Conference Paper)In this paper, we study and analyze cooperative cognitive radio networks with multiple secondary users (SUs). Each SU is considered a prospective relay for the primary user (PU) besides having its own data demand. The ... -
Understanding probabilistic cognitive relaying communication with experimental implementation and performance analysis
( MDPI AG , 2019 , Article)Efficiently use of the limited wireless spectrum can be achieved by cooperative cognitive relaying, where secondary users (SUs), who do not pay for the licensed spectrum and have better channel condition to the primary ...
