Impact of channel estimation errors on effectiveness of Eigenvector-based jamming for physical layer security in wireless networks

Abstract

Abstract-Nowadays, multimedia application and video streaming have gained a great popularity because of the boasting development on mobile hardware, and battery driven devices have emerged with a tremendous speed. Due to the important issue of battery efficiency on mobile devices, many optimization algorithms have being proposed toward various of battery powered platforms and scenarios. Most of the provided solutions choose to aim at the minimization of energy usage under a given task scheduling by adjusting parameters reside in the processes of different schemes. However, the battery discharging characteristics and its instant output pattern are still ignored if the optimization is done only from high level adjustment. In this paper, we propose a battery-aware optimization framework toward the H.264 video coding by applying dynamic frequency scaling on hardware platform. The CPU frequency can be dynamically adjusted according to the instant status of battery in order to maximize the number of the coding frame. Experimental results indicate the efficiency and effectiveness of the proposed optimization framework.

Secure On-Off Transmission Design With Channel Estimation Errors

“…Specifically, Taylor et al presented the impact of the legitimate receiver's channel estimation error on the performance of an eigenvector-based jamming technique in [12]. Their research showed that the ergodic secrecy rate provided by the jamming technique decreases rapidly as the channel estimation error increases.…”

“…The aforementioned works in [12][13][14] all used the ergodic secrecy rate to characterize the performance limits of systems. The ergodic secrecy rate is an appropriate secrecy measure for systems in which the encoded messages span sufficient channel realizations to capture the ergodic features of the fading channel [15].…”

A Comprehensive Survey on Cooperative Relaying and Jamming Strategies for Physical Layer Security

“…For instance, the CSI of the legitimate user is usually obtained by feedback. A handful of studies under jamming have evaluated the secrecy performance of under imperfect channel estimation for imperfect legitimate channel [241] and for main and jamming links [242], [182], [243]. In addition, these works derive lower or upper bounds, and closed-form expressions for aforementioned scenarios are largely missing in the literature.…”

Impact of channel estimation error on secure transmission design

“…Therefore, it is worthwhile investigating the impact of the legitimate receiver's channel estimation error on the secure transmission. Initial works that considered imperfect CSI of the legitimate receiver and no CSI of the eavesdropper can be found in [3][4][5].…”

“…In [3], Taylor et al presented the impact of the legitimate receiver's channel estimation error on the performance of an eigenvector based jamming technique. Their research showed that the secrecy capacity provided by the jamming technique decreases rapidly as the channel estimation error increases.…”
