In fifth-generation (5G) and beyond (B5G) communication systems, the growing number of connected devices and the increased traffic on the network lead to substantial energy consumption, which requires energy-efficient and high-speed communication solutions. Integrating non-orthogonal multiple access (NOMA), energy harvesting (EH), and millimeter wave (mmWave) technologies has emerged as a powerful...Show More
Autonomous security unmanned aerial vehicles (UAVs) have recently gained popularity as an effective solution for accomplishing target/intrusion detection and tracking tasks with little or no human intervention. In this context, we aim at developing an autonomous UAV system for detecting a dynamic and uncertain intrusion within an area, in which the intruder/target moves from one location to anothe...Show More
Biometric systems have advanced greatly in this field of technology and can be used to many other uses. It is common practice to employ biometric systems for authentication, which involves identifying and analyzing unique human traits including fingerprints, retina, voice patterns, facial patterns, and more. Facial recognition technology is also being developed and used for a wide range of purpose...Show More
Due to their distinctive features, unmanned aerial vehicles (UAVs) have been recently exploited to support a wide range of applications. The features include low maintenance cost, compact size, and excellent capability of maneuvering. In particular, UAVs have the potential capabilities to support different technologies such as Internet-of-things (IoT) devices, sensors, cameras, and systems, thus, ...Show More
Every year, wildfires burn out countless hectares of lands, resulting in ecological, environmental, and economic damage. This paper presents an energy management system that consists of an unmanned aerial vehicle (UAV) equipped with air quality and light detection and ranging (LiDAR) sensors for monitoring forests and recognizing flames early. We develop a novel approach for autonomous patrolling ...Show More
The recent development of Unmanned aerial vehicle (UAV) technology and the UAVs' unique features offered the impetus for new UAV-based applications and services. The UAV's low maintenance cost, small size, outstanding maneuvering capability, and the possibility to be equipped with various technologies(e.g., sensors, cameras, and artificial intelligence (AI) systems) made the UAV-based systems suit...Show More
In this paper, the drone base-station (DBS) dispatching problem in a multi-cell B5G/6G network is investigated. The main objective is to achieve the highest system profit by serving the largest possible number of users with the least possible cost while considering the uncertain time-dependent fluctuated user’s (service) demand in the different cells, the cost of dispatched drones, and the possibl...Show More
Autonomous unmanned aerial vehicles are able to sense their surrounding environments, and fly safely with little or no human intervention. Autonomous unmanned aerial vehicles are characterized by their ability to make decisions based on predicting future possible situations and learning from previous experiences. In this paper, we aim at developing algorithms that enable unmanned aerial vehicles t...Show More
This work investigates the performance of an energy harvesting communications system. This system consists of a transmitter and a receiver. The transmitter is equipped with an infinite buffer to store data, and energy harvesting capability to harvest renewable energy and store it in a finite battery. The goal is to maximize the expected cumulative throughput of such systems. The problem of finding...Show More
In this work, we propose efficient channel assignment as well as transmission power control (TPC) algorithm to improve the performance of multi-channel single-radio cognitive radio ad-hoc networks (CRAHNs). The channel assignment algorithm aims to assign channels among users in a way that reduces the probability of collision. The TPC aims to tune the transmit power used by nodes. By this mechanism...Show More
This work presents two reinforcement learning (RL) architectures, which mimic rational humans in the way of analyzing the available information and making decisions. The proposed algorithms are called selector-actor-critic (SAC) and tuner-actor-critic (TAC). They are obtained by modifying the well known actor-critic (AC) algorithm. SAC is equipped with an actor, a critic, and a selector. The role ...Show More
Energy harvesting communications systems are able to provide high quality communications services using green energy sources. This paper presents an autonomous energy harvesting communications system that is able to adapt to any environment, and optimize its behavior with experience to maximize the valuable received data. The considered system is a point-to-point energy harvesting communications s...Show More
Data forwarding from a source to a sink node when they are not within the communication range is a challenging problem in wireless networking. With the increasing demand of wireless networks, several applications have emerged where a group of users are disconnected from their targeted destinations. Therefore, we consider in this paper a multi-Unmanned Aerial Vehicles (UAVs) system to convey collec...Show More
Prolonging the lifetime, and maximizing the throughput are important factors in designing an efficient communications system, especially for energy harvesting-based systems. In this work, the problem of maximizing the throughput of point-to- point energy harvesting communications system, while prolonging its lifetime is investigated. This work considers more real communications system, where this ...Show More
Cognitive radio networks with energy harvesting result in efficient use of both energy and spectrum. By using cooperative relaying, another feature can be achieved, which is the high diversity gain. In this paper, an energy harvesting underlay cognitive radio relaying network is investigated. In this underlay cognitive radio scheme, secondary users are allowed to access the spectrum, respecting a ...Show More
