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 ...
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 ...
