Adaptive bit-loading in relay-aided cognitive radio network
Siddiqi, Muhammad Zain; Furqan, Haji Muhammad; Jabeen, Tayyaba; Ali, Zain; Sidhu, Guftaar Ahmad Sardar (Institute of Electrical and Electronics Engineers Inc., 2017)In this work, we consider a joint power allocation and bit loading problem in an orthogonal frequency division multiplexing (OFDM) based cognitive radio (CR) network. The objective is to maximize the end-to-end rate in a ... -
An efficient security method based on exploiting channel state information (CSI)
Hamamreh, Jehad M.; Furqan, Haji Muhammad; Ali, Zain; Sidhu, Guftaar Ahmad Sardar (Institute of Electrical and Electronics Engineers Inc., 2017)A channel amplitude quantization method that can effectively quantize the channel response using just one single threshold value is proposed in order to extract a random manipulating sequence with good secrecy properties. ... -
Enhancing physical layer security in AF relay-assisted multicarrier wireless transmission
Aman, Waqas; Sidhu, Guftaar Ahmad Sardar; Furqan, Haji Muhammad; Ali, Zain (Wiley, 2018)In this paper, we study the physical layer security problem in the dual-hop orthogonal frequency division multiplexing-based wireless communication system. First, we consider a single-user single-relay system and study a ... -
Enhancing the security performance of ostbc using pre-equalicodization
Hamamreh, Jehad M.; Furqan, Haji Muhammad; Ali, Zain; Sidhu, Guftaar Ahmad Sardar (Institute of Electrical and Electronics Engineers Inc., 2017)In this study, we first quantify the secrecy performance achieved by employing precoded orthogonal space time block coding (POSTBC) in order to use it as a benchmark for comparison purposes with a new proposed security ... -
On fair interference management in cognitive radio networks
Musab, Muhammad; Ali, Zain; Furqan, Haji Muhammad; Amanat, Irtiza; Jabeen, Tayyaba; Sidhu, Guftaar Ahmad Sardar (Institute of Electrical and Electronics Engineers Inc., 2017)In this paper, we consider power optimization problem in cognitive radio (CR) networks. The aim is to protect the licensed primary users (PUs) from unequal performance degradation by secondary users (SUs). A min-max ... -
Optimizing D2D transmission for secure and reliable smart grid communication
Waqas, Muhammad; Ali, Zain; Furqan, Haji Muhammad; Sidhu, Guftaar Ahmad Sardar (IEEE Computer Society, 2017)Smart grid (SG) has been recognized as a promising solution to manage and distribute electricity in the next generation power systems. The large number of devices in power systems make the wired communication a non feasible ... -
User association for enhancing physical layer security in heterogeneous network
Furqan, Haji Muhammad; Sidhu, Guftaar Ahmad Sardar; Arslan, Hüseyin (Springer, 2019)In this work, a fair user association scheme is proposed for heterogeneous networks aiming to enhance physical layer security (PLS). More specifically, the user association problem is formulated as a Nash bargaining problem ... -
User association techniques in future heterogeneous networks
Bakht, Khush; Furqan, Haji Muhammad; Ali, Zain; Sidhu, Guftaar Ahmad Sardar (Institute of Electrical and Electronics Engineers Inc., 2017)The exponential increase in the demand of data rate and scarcity of the available spectrum have evolved to the more advanced network topology which efficiently utilizes the radio spectrum such as Heterogeneous Networks ...
