Transmit and receive cooperative cognition: Protocol design and stability analysis
El Shafie, Ahmed; El-Keyi, Amr; Khattab, Tamer; Nafie, Mohamed ( IEEE Computer Society , 2013 , Conference Paper)In this paper, we investigate the stability of a cooperative cognitive system. We propose a cooperative secondary transmitter-receiver system (CSTR), where, the secondary transmitter (ST) and the secondary receiver (SR) ... -
Underlay cognitive radio : What is the impact of carrier aggregation and relaying on throughput ?
Diamantoulakis, Panagiotis D.; Pappi, Koralia N.; Muhaidat, Sami; Karagiannidis, George K.; Khattab, Tamer ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)In this paper, we investigate joint relay selection and optimal power allocation, as a means to maximize the achievable rate of an underlay cooperative cognitive radio with carrier aggregation, taking into account the ... -

Unleashing the secure potential of the wireless physical layer: Secret key generation methods
Badawy, Ahmed; Elfouly, Tarek; Khattab, Tamer; Mohamed, Amr; Guizani, Mohsen ( Elsevier B.V. , 2016 , Report)Within the paradigm of physical layer security, a physical layer characteristic is used as a common source of randomness to generate the secret key. This key is then used to encrypt the data to hide information from ... -
