	abstract = {Recently, air pollution has grown significantly, and it can frequently be challenging to identify the sources of contaminants. This article studies the deployment of multi-cooperative unmanned aerial vehicles (UAVs) to look for sources of pollution in an unknown region. Specifically, a probabilistic search strategy based on the Local Particle Swarm Optimization (LoPSO) method is suggested to design an optimal strategy that enhances the cooperative search of drones while cutting down on overall search time and improving source detection efficiency. The entire strategy is divided into two phases: exploration and exploitation. In the first phase, the detection and tracing of the plume is the favored task, in which each UAV operates in either the Greedy or LoPSO mode and chooses its path based on plane coordinates generated according to the active mode. By utilizing the areas with a high probability of discovering the source on flight mode LoPSO, the search is focused during the exploitation phase on the precise search of the exact location of the pollutant source. This is done under the direction of a probabilistic computation that uses the Bayesian process model to create and update the probability map of the pollutant source location as new sensor data becomes available. The simulation data of the proposed technique demonstrates promising results in terms of the complexity and accuracy attained in identifying pollution sources. {\textcopyright} 2013 IEEE.},

	abstract = {Impairments baseband model in-phase and quadrature-phase Imbalance (IQI) and Residual hardware impairments (RHI) are two key factors degrading the performance of wireless communication systems (WCSs), particularly when high-frequency bands are employed, as in 5G systems and beyond. The impact of either IQI or RHI on the performance of various WCSs has been investigated exclusively in a separate way. To fill this gap, in this paper, the joint effect of both IQI and RHI on the performance of a WCS subject to Hyper Fox{\textquoteright}s H-fading (HFHF) channel, is investigated. Such a fading model generalizes most, if not all, of well-known fading and turbulence models. To this end, closed-form expressions for the outage probability (OP), Average channel capacity (ACC) under constant power with optimum rate adaptation (ORA) policy, and average symbol error probability (ASEP) for both coherent and non-coherent modulation schemes are derived. Specifically, all the analytical expressions are derived for three different scenarios: (i) ideal Tx and Rx impaired, (ii) Tx impaired and ideal Rx, and (iii) both Tx and Rx are impaired. Further, asymptotic expressions for OP, ACC under ORA policy, and ASEP are obtained, based on which, insightful discussions on the IQI and RHI impacts are made. α-μ and M{\'a}laga M turbulence with pointing error distribution models have been considered as particular cases of the HFHF distribution. The analytical derivations, endorsed by simulation results, demonstrate that the RF impairments{\textquoteright} effects should be seriously taken into account in the design of next-generation wireless technologies. {\textcopyright} 2002-2012 IEEE.},

	abstract = {In this paper, we analyze the physical layer security of a jamming-aided wireless communication system assisted by a reconfigurable intelligent surface (RIS). Our setup consists of a source node communicating with a destination node with the help of a RIS, and under the presence of a malicious passive eavesdropper attempting to overhear the genuine transmission. Furthermore, an external cooperative jammer is incorporated to reinforce the system{\textquoteright}s secrecy by broadcasting an artificial noise to disrupt the eavesdropper; such a noise can be removed at the destination. Finally, we assume that the tunable RIS phases based on the channel estimates are subject to quantization errors. By virtue of the well-adopted Gamma and Exponential distributions approximations, an approximate expression for the system{\textquoteright}s intercept probability (IP) is derived in terms of the main setup parameters. The results show that the greater the number of reflective elements (REs) and jamming power, the better the secrecy, while the number of quantization bits has less impact when exceeding 3 bits. In particular, an IP of 10-3 can be reached with 50 REs even when the legitimate link{\textquoteright}s average signal-to-noise ratio (SNR) is 15 dB below the wiretap channel{\textquoteright}s average SNR.

	abstract = {Limited resources, such as energy, processing power, memory, and communication bandwidth, limit the usage of multi-UAV systems in the target search domain. The limitation of energy, in particular, has a significant impact on the system{\textquoteright}s performance, especially because the overall energy consumption is frequently dominated by the cost of communication, i.e. the computational and sensing energy are insignificant in comparison to the communication energy consumption. As a result, the system{\textquoteright}s lifetime may be considerably prolonged by reducing the communication as well as the volume of communication data, at the penalty of increased computing cost. This work presents a hierarchic approach for allocating multi-UAV resources based on a cooperative and competitive particle swarm optimization (PSO) algorithm, with the goal of achieving an optimal balance between communication and processing energy. According to the simulation findings, our technique can save a substantial amount of energy when compared to a benchmark strategy namely random search (RS) and PSO. {\textcopyright} 2021 IEEE.},

Their importance becomes a requirement in highly mobile and volatile environments, such as vehicular ad-hoc networks (VANET). In the present work, we propose a dynamic and decentralized reputation system that fits VANET characteristics like dynamism and volatility without conceding on security. The novel system uses blockchain for reputation information aggregation and storage and secure multiparty computation (SMC) to achieve privacy. Unlike previous VANET reputation systems, our system does not rely on a central authority to evaluate trustworthiness. Instead, it limits its role to maintaining the blockchain and system integrity leaving reputation evaluation to peers. It preserves feedback privacy in the presence of up to n - 2 dishonest parties and shows good performance. Remarkably, our system takes advantage of the infrastructure of VANET when vehicles are nearby while remaining fully functional in extra-urban areas. {\textcopyright} 2021 IEEE.},

Firstly, new accurate approximations of error probability (EP) of both modulation schemes are derived over additive white Gaussian noise (AWGN) channel. Leveraging the trapezoidal integral method, a tight approximate expression of symbol error probability for M-PSK modulation is presented, while new upper and lower bounds for Marcum Q-function (MQF) of the first order, and subsequently those for bit error probability (BEP) under DQPSK scheme, are proposed. Next, these bounds are linearly combined to propose a highly refined and accurate BE P{\textquoteright}s approximation. The key idea manifested in the decrease property of modified Bessel function Iv, strongly related to MQF, with its argument v. As an application, these approximations are used to tackle AEP{\textquoteright}s approximation under κ - {\textmu} shadowed fading.

	abstract = {Nowadays, the cybersecurity issue involves new strategies to protect against advanced threats and unknown attacks. Intrusion detection system (IDS) is considered a robust system dealing with attacks detection, particularly unknown attacks and anomalies. Several IDS-based algorithms have been recently inspected in the literature, among them the well-known strengthen algorithms, i.e. Genetic algorithm (GA). Moreover, Epigenetic-based algorithm (EGA) is known as an improved version of GA ensuring high performance with reduced computational complexity. Its main goal is to converge within a short time towards an optimal solution by acting on genetic operators, namely mutation and crossover. In this article, we propose a new classifier based on EGA for IDS. Especially, based on a database of network traffics, EGA is applied to classify attacks. The results, performed through EGA simulation, show that the performance of the proposed technique outperforms the ones of GA classifier by obtaining a high detection rate up to 98\% and a faster processing time than that of GA and other algorithms that we have compared in this article. {\textcopyright} 2020 BMJ Publishing Group.

	abstract = {Hybrid terrestrial-satellite (HTS) communication systems have gained a tremendous amount of interest recently due to the high demand for global high data rates. Conventional satellite communications operate in the conventional Ku (12 GHz) and Ka (26.5-40 GHz) radio-frequency bands for assessing the feeder link, between the ground gateway and the satellite. Nevertheless, with the aim to provide hundreds of Mbps of throughput per each user, free-space optical (FSO) feeder links have been proposed to fulfill these high data rates requirements. In this paper, we investigate the physical layer security performance for a hybrid very high throughput satellite communication system with an FSO feeder link. In particular, the satellite receives the incoming optical wave from an appropriate optical ground station, carrying the data symbols of N users through various optical apertures and combines them using the selection combining technique. Henceforth, the decoded and regenerated information signals of the N users are zero-forcing (ZF) precoded in order to cancel the interbeam interference at the end-users. The communication is performed under the presence of malicious eavesdroppers nodes at both hops. Statistical properties of the signal-to-noise ratio of the legitimate and wiretap links at each hop are derived, based on which the intercept probability metric is evaluated. The derived results show that above a certain number of optical apertures, the secrecy level is not improved further. Also, the system{\textquoteright}s secrecy is improved using ZF precoding compared to the no-precoding scenario for some specific nodes{\textquoteright} positions. All the derived analytical expressions are validated through Monte Carlo simulations. {\textcopyright} 2021 Institute of Electrical and Electronics Engineers Inc.. All rights reserved.},

	abstract = {In this paper, the physical layer security of a dual-hop underlay uplink cognitive radio network is investigated over Nakagami-m fading channels. Specifically, multiple secondary sources (S_i)_1{\l}eq i{\l}eq N are taking turns in accessing the licensed spectrum of the primary users and communicating with a multi-antenna secondary base station (D) through the aid of a multi-antenna relay R in the presence of M eavesdroppers (E_k)_1{\l}eq k{\l}eq M that are also equipped with multiple antennas. Among the remaining nodes, one jammer is randomly selected to transmit an artificial noise to disrupt all the eavesdroppers that are attempting to intercept the communication of the legitimate links, i.e., S_i-R and R-D. The received signals at each node are combined using maximum-ratio combining. Secrecy analysis is provided by deriving closed-form and asymptotic expressions for the secrecy outage probability. The impact of several key parameters on the system{\textquoteright}s secrecy, e.g., transmit power of the sources, number of eavesdroppers, maximum tolerated interference power, and the number of diversity branches is investigated. Importantly, by considering two scenarios, namely (i) absence and (ii) presence of a friendly jammer, new insights are obtained for the considered communication system. Especially, we tend to answer to the following question: Can better secrecy be achieved without jamming by considering a single antenna at eavesdroppers and multiple-ones at the legitimate users (i.e., relay and end-user) rather than sending permanently an artificial noise and considering that both the relay and the destination are equipped with a single antenna, while multiple antennas are used by the eavesdroppers? The obtained results are corroborated through Monte Carlo simulation and show that the system{\textquoteright}s security can be enhanced by adjusting the aforementioned parameters. {\textcopyright} 2015 IEEE.},

We present a decentralized control model for cooperative target-searching and we develop a real-time approach for direct cooperation between vehicles, which is based on calculating the minimum time required to reach a cell. Each UAV takes into account the possible actions of other UAVs to increase the overall information about the environment. The simulation results illustrate the effectiveness of the proposed strategy by comparing it with the free moving strategy and show that our proposed algorithm performs out it. {\textcopyright} 2017 ACM.},

Our system model consists of two communication paths, and the receiver uses the MRC combining scheme to combine the received signals through these both links. The first optical link consists of a source (S) and a destination (D) nodes communicating through a relay node (R), which receives the incoming information-bearing signal and forwards it to the destination (i.e. detect-and- forward relaying (Det-F)). Both (S-R) and (R-D) hops are operating under FSO link subject to Malaga-M turbulence model with the presence of pointing error. The second link is a direct RF link, connecting the source (S) directly to the destination (D), and is assumed to be subject to Rayleigh fading channel. We present in this paper the exact closed-form expression of the moment-generating function (MGF) of the total end-to-end SNR.

Our proposed protocol uses cryptography to ensure a confidential communication between the source and the destination.

We also evaluate the average bit error rate (ABER) for several coherent and non-coherent modulation schemes, using a closed-form expression for the moment-generating function (MGF) of the output SNR for MRC receivers. In addition, we derive some analytical expressions for channel capacity under various adaptation policies such as optimal rate adaptation (ORA), Optimal simultaneous power and rate adaptation (OPRA), Channel inversion with fixed rate (CIFR), and Truncated channel inversion with fixed rate (TCIFR). The proposed mathematical analysis is complemented by numerous numerical results, which point out the effects of fading severity on the overall system performance. Computer simulations are also performed to verify the validity and the accuracy of the proposed theoretical approach. {\textcopyright} 2016},

Approximating the output SNR by a simple H-distribution, useful closed formulas for cumulative distribution function, moment generating function, outage probability, amount of fading, average capacity, and average symbol error rate for some M-Ary modulation schemes are derived in terms of Meijer G-function. All results are illustrated and validated by computed simulations using Mathematica software. {\textcopyright} 2014 IEEE.},
