Nowadays, one of the most common approaches for video watermarking is to use singular value decomposition in the discrete wavelet transform domain. In our prior work, we formulated a video watermarking problem to achieve the maximum peak signal to noise ratio as an optimization problem. It chooses wavelet coefficient points in key frames with minimum distortion cost. Yet the existing solution has two drawbacks (1) it requires to store a large number of coordinates depending on the watermark size; (2) it is vulnerable to video frame attacks on the video frame texture area. To avoid them, this p...

This article considers deriving set covers or the set of active nodes that are responsible for monitoring all targets in an Internet of Things (IoT) network. A key distinction to prior works is that this article considers sensor nodes aided by backscatter communications, which allow them to communicate with negligible energy cost using ambient radio frequency (RF) signals. The article contains three main novelties. First, it presents a mixed integer linear program (MILP) that can be used to compute the global optimal solution. Second, it also outlines a centralized greedy scheduling (CGS) algo...

This study proposes a solid-state transfer switch (SSTS) using fuzzy logic controller (FLC) design approach for enhancing the productivity and effectiveness of FLCs under harmonics conditions of a non-linear load using particle swarm optimization (PSO). A PSO-based FLC (PSOF) fitness function is also used to optimise and reduce the MSE to enhance the load transfer performance in a short period of time. The PSOF approach eliminates the time-consuming conventional trial-and-error method of deriving membership functions (MFs). Based on the fitness function evaluation findings, the created adaptiv...

This article studies targets coverage in an energy harvesting (EH) Internet of Things (IoT) network. Specifically, it addresses the problem of activating subsets of EH sensor nodes to monitor targets, such as valuable assets or the ingresses and egresses of a building. A key requirement, so called complete targets coverage, is that all targets must be monitored by at least one sensor node at all times. To meet this requirement, we need to derive set covers, where each set cover is comprised of one or more sensor nodes that are activated simultaneously in each time slot. To this end, we show fo...
