Channel secondary random process for robust secret key generation
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)The broadcast nature of wireless communications imposes the risk of information leakage to adversarial users or unauthorized receivers. Therefore, information security between intended users remains a challenging issue. ... -
Doppler compensation for AF two way relaying over time varying UWA channels
( IEEE , 2014 , Conference Paper)In this paper, we consider Doppler compensation for time varying underwater acoustic channels. The underlying system model comprises two sources, S1 and S2, communicating with each other through a relay, R. The transmission ... -
Joint Optimization of Area Spectral Efficiency and Delay over PPP Interfered Ad-Hoc Networks
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Article)To evaluate the performance of the co-channel transmission based communication, we propose a new metric for area spectral efficiency (ASE) of interference limited ad-hoc network by assuming that the nodes are randomly ... -
Location privacy preservation in secure crowdsourcing-based cooperative spectrum sensing
( Springer International Publishing , 2016 , Article)Spectrum sensing is one of the most essential components of cognitive radio since it detects whether the spectrum is available or not. However, spectrum sensing accuracy is often degraded due to path loss, interference, ... -
Robust secret key extraction from channel secondary random process
( John Wiley and Sons Ltd , 2016 , Conference Paper)The vast majority of existing secret key generation protocols exploit the inherent randomness of the wireless channel as a common source of randomness. However, independent noise added at the receivers of the legitimate ...
