Cooperative access in cognitive radio networks: Stable throughput and delay tradeoffs
Ashour, Mahmoud; El-Sherif, Amr A.; Elbatt, Tamer; Mohamed, Amr ( 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
Ashour, Mahmoud; Butt, Muhammad Majid; Mohamed, Amr; ElBatt, Tamer; Krunz, Marwan ( 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 ... -
MIMO vehicle to vehicle channels: An experimental study
Ashour, Mahmoud; Attia, Ahmed; Elmoslimany, Ahmad; Mohasseb, Yahya; El-Keyi, Amr ( IEEE , 2014 , Conference Paper)In this paper, a platform for measuring the impulse response of wireless multiple-input-multiple-output (MIMO) vehicle-to-vehicle (V2V) channels is presented. The platform is developed using Rice University Wireless ... -
On the power efficiency for cognitive radio networks with multiple relays
Ashour, Mahmoud; Butt, M. Majid; Mohamed, Amr ( 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 ...
