With accelerated advances in various technologies, drones, better known as unmanned aerial vehicles (UAVs), are increasingly commonplace and consequently have a more pronounced impact on society. For example, Internet of Drones (IoD), new communication paradigm offering fundamental navigation assistance access to information, has widespread applications ranging from agricultural drones farming surveillance the COVID-19 pandemic. The prominent role IoD our society also reinforces importance...

In this letter, we propose joint relay selection and power allocation schemes for maximization of the throughput an amplify-and-forward (AF) cooperative communication system where source relays are energy harvesting (EH) nodes. We formulate offline optimization problem which can be solved optimally by generalized Bender's decomposition. For real-time implementation with low computational complexity, two suboptimal online schemes. The performance proposed is evaluated via simulations.
In the dynamic and ever-changing domain of Unmanned Aerial Vehicles (UAVs), utmost importance lies in guaranteeing resilient lucid security measures. This study highlights necessity implementing a Zero Trust Architecture (ZTA) to enhance unmanned aerial vehicles hence departing from conventional perimeter defences that may expose vulnerabilities. The paradigm requires rigorous continuous process authenticating all network entities communications. accuracy our methodology detecting...

Our objective to maximize system throughput over a finite...
In this work, we consider a point-to-point communication link where the transmitter has hybrid supply of energy. Specifically, energy is supplied by constant source and an harvester, which harvests from its surrounding environment stores it in battery suffers leakage.

Two scenarios are considered packet arrival. first scenario, assume that all packets have arrived before begins, whereas second...
