A Chaotic Compressive Sensing‐Based Secure Device‐to‐Device Communication
IET Communications, Volume 20, Issue 1, January/December 2026.This research proposes the construction of a single combined measurement matrix built from two discrete chaotic sequences for enhanced randomness in the data. Additionally, a separate chaotic system is used in a novel way to construct orthogonal matrices. ABSTRACT The need for secure information exchange is increasingly felt with an exponential rise in

Application-aware protection in DWDM optical networks [PDF]
2011 20th Annual Wireless and Optical Communications Conference (WOCC), 2011 Fast recovery time and reduced resource utilization are the two main criteria for determining the quality of survivability mechanism. Now, it is well known that link-based protection and path-based protection provide, respectively, a short recovery time and reduced use of resources. To benefit from the both of these saliencies, we propose in this paper
