	abstract = {In this paper, the performance analysis of simultaneous wireless information and power transfer (SWIPT) using time switching (TS) protocol-based amplify-and-forward (AF) dual-hop mixed radio-frequency/free-space optic (RF/FSO) coded and uncoded communication system (CC and UC) is investigated. Specifically, we look at using the One-Step Majority-Logic Decodable (OSMLD) codes at the source and a majority logic decoding algorithm (MLGD) at the destination, jointly with the use of maximal-ratio combining and SWIPT/TS techniques at the relay. Furthermore, the RF link undergoes Nakagami-m model, while the second-hop is subject to M\&$\#$x00E1;laga-M atmospheric turbulence with the effect of pointing errors. Closed-form and asymptotic formulations for the average bit error probability (ABEP) are obtained in terms of the system parameters for both CC and UC scenarios in addition of the average channel capacity analysis. Computer-based Monte Carlo simulations were used to numerically validate all of the obtained mathematical formulations. Expectedly, it is shown that significant coding gains are achieved using OSMLD codes in comparison with UC. In addition, above a specific threshold of energy efficiency, the system performance gets steady in the high signal-to-noise-ratio regime. Moreover, the decoding method used in this work has been shown to be suitable for the SWIPT/TS-assisted RF/FSO coded AF cooperative communication system where high performance alongside low computational complexity are required.

	abstract = {This paper investigates the intercept probability (IP) performance for a dual-hop multi-secondary user (SU) underlay cognitive-radio networks. Whereby, the relay R is self-powered by harvesting energy from secondary sources using the time switching variant (TS) of simultaneous wireless information and power transfer (SWIPT) protocol. Single-antenna SUs are transmitting data to multi-antennas end-user D, performing maximal-ratio combining (MRC) diversity technique, through R in presence of (i) a primary network composed of a primary transmitter (PUt) and receiver (PUr) pair, and (ii) a passive eavesdropper at each hop (i.e., E1 and E2), attempting to overhear the communication. Moreover, we suppose that the second eavesdropper has multiple antennas and employs the MRC technique, that the relay employs the Decode-and-Forward relaying protocol, that the two hops are subject to the Rayleigh fading model, and that the channel state information is fully known at both D and E2. Because of the underlying strategy, the SUs are constantly modifying their transmit powers to prevent interference with primary users. A closed-form expression of the IP is obtained by taking into consideration the correlation between the secrecy capacities for both hops. The impact of other essential factors on IP, such as the transmit power of sources, the fading severity parameter, and the maximum tolerable interference power (MTIP), is also investigated. Specifically, we want to know if the energy harvester (i.e., relay) might improve the security of such a system even more for low MTIP or transmit power of SUs. Monte Carlo simulations verify all of the obtained results, and valuable insights into the secrecy of the considered system are achieved. IEEE},

	abstract = {Evaluating the sum of independent and not necessarily identically distributed (i.n.i.d) random variables (RVs) is essential to study different variables linked to various scientific fields, particularly, in wireless communication channels. However, it is difficult to evaluate the distribution of this sum when the number of RVs increases. Consequently, the complex contour integral will be difficult to determine. Considering this issue, a more accurate approximation of the distribution function is required. By assuming the probability density function (PDF) of a generalized gamma (GG) RV evaluated in terms of a proper subset H1,0 class of Fox{\textquoteright}s H-function (FHF) and the moment-based approximation to estimate the FHF parameters, a closed-form tight approximate expression for the distribution of the sum of i.n.i.d GG RVs and a sufficient condition for the convergence are investigated. The proposed approximate may be an analytical useful tool for analyzing the performance of certain numbers branch maximal-ratio combining receivers subject to GG fading channels. Hence, various closed-form performance metrics are derived and examined in terms of FHF. Numerical simulations are carried out to illustrate the theoretical results. {\textcopyright} 2021.

Specifically, we report, based on the UAV{\textquoteright}s scan of a location and taking into account (i) the detection and communication coverage limitations, and (ii) either a false alarm or inaccurate detection of the target, either the existence or the absence of the target. Moreover, leveraging a cooperative and competitive particle swarm optimization (PSO) algorithm, a decentralized target search model, relying on a real-time dynamic construction of cooperative UAV local sub-swarms (LoPSO), is proposed. Each sub-swarm strives to validate quickly the target location, updated based on the Bayesian theory. In such a strategy, each UAV operates in two flight modes, namely, either in swarm mode or in Greedy mode, and takes into consideration the received data from other UAVs to improve the overall environmental information. The simulation results revealed that the LoPSO outperforms other well-known searching methods of target methods for target search in unknown environments in terms of both performance and computational complexity. {\textcopyright} 2013 IEEE.},

	abstract = {Ensuring physical layer security is a crucial task in conventional and emerging communication systems, which are typically characterized by stringent quality of service and security requirements. This also accounts for wireless technologies in the context of the Internet of Things paradigm, which are expected to exhibit considerably increased computational complexity. Based on this, the present contribution investigates the secrecy outage performance of a dual-hop decode-and-forward (DF) mixed radio-frequency/underwater optical wireless communication (RF/UOWC) system. Such wireless network configurations are particularly useful in efficient and demanding scenarios, such as military communications. Therefore, our analysis considers one single-antenna source node (SS) communicating with one legitimate destination node (DD) via a DF relay node (RR) equipped with multiple antennas for reception. Particularly, the relay receives the incoming signal from SS via an RF link, applies selection-combining (SC) technique, fully decodes it, re-encodes it, and then forwards it to the destination via a UOWC link. The communication is performed under the eavesdropper{\textquoteright}s attempt to intercept the S-RS-R hop (RF side). In this context, a closed-form expression for the secrecy outage probability is derived along with a thorough asymptotic analysis in the high SNR regime, based on which the achievable diversity order is provided. The offered results provide useful insights on the impact of some key system and channel parameters on the secrecy outage performance, such as the number of eavesdroppers, the number of relay antennas, fading severity parameters of RF links, and water turbulence severity of the UOWC link. The conducted analysis shows that the secrecy outage probability is dominated only by the RR-DD link in the high SNR regime, regardless of the SS-RR parameters, such as the number of relay antennas and the average SNR at the relay branches. The offered analytic results are corroborated with respective results from computer simulations. Since these parameters are closely related with the computational complexity at the involved terminals, the offered insights are useful for the design and computationally sustainable operation of such systems. {\textcopyright} 2016 IEEE.},

In particular, the probability density function of MRV is approximated by a Fox{\textquoteright}s H-function through the moment-based approach. Then, the respective moment-generating function of the sum of N MRVs is provided, based on which the average symbol error rate is evaluated for an N-branch maximal-ratio combining (MRC) receiver. The retrieved results show that the proposed approximate results match accurately with the exact simulated ones. Additionally, the results show that the achievable diversity order increases as a function of the number of MRC diversity branches. {\textcopyright} 1967-2012 IEEE.},

	abstract = {Hybrid terrestrial-satellite transmission systems have been among hottest spots in the wireless communication industry due to the high demand for global high data rates. In such systems, free-space optical (FSO) technology is advocated for assessing the feeder links (ground-satellite) in order to fulfill high data rates requirements and provide a larger coverage in terms of the connected number of users. This paper gives an overview of various components of very-high throughput hybrid terrestrial-satellite communication system with an FSO feeder link, and Ka-band multibeam RF channels for the satellite ground link. In this survey paper, we depict the main communication challenges in the FSO side such as pointing error, turbulence, cloud blockage, and also the multibeam RF side such as spectrum scarcity, inter-beam interference, and security. Based on these challenges we point out some potential research directions. {\textcopyright} 2020 IEEE.},

	abstract = {Cognitive radio (CR) is a promising paradigm that comes to address the scarcity of the radio spectrum by providing opportunistic utilization of the underutilized licensed channels to attain higher spectrum efficiency. The efficient use of the vacant portion of the spectrum depends directly on the medium access control (MAC) layer that coordinates fairly the access of the CR nodes to the idle spectrum. However, the MAC layer is vulnerable to several attacks driven by malicious nodes. One of those attacks is the backoff manipulation attack (BMA), where the selfish attacker deviates from the defined contention mechanism to gain inequitable access to the available channels. This unfair access presents some specific characteristics of an attacker, which can be considered as an input to the supervised machine learning algorithm for classification. In this paper, we propose a support vector machine (SVM) based model in order to distinctively identify the attacker depending on the throughput and the average packet delay to classify/predict an eventual attack. Finally, theoretical predictions and simulation results are presented to validate the proposed framework while giving useful insights into CR systems{\textquoteright} performance, vulnerable to BMA attacks. {\textcopyright} 2013 IEEE.},

	abstract = {By considering the probability density function (PDF) of a generalized Gamma (GG) random variable (RV) evaluated in terms of a proper subset (Formula presented) class of Fox{\textquoteright}s H-function (FHF) and the moment-based approximation to estimate the H-function parameters, a closed-form tight approximate expression for the distribution of the sum of independent and not necessarily identical GG distributed RVs is presented as well as a sufficient condition for the convergence is verified. Such proposed approximate PDF is useful analytical tool for analyzing the performance of L-branch maximal-ratio combining receivers subject to such a fading model. This result can be also of paramount importance when dealing with an intelligent reflecting surface subject to GG fading channels. Furthermore, various closed-form approximate expressions, such as the cumulative distribution function (CDF), moment-generating function, outage probability (OP), average channel capacity, nth moment of the signal-to-noise ratio (SNR), amount of fading, and average symbol error probability (ASEP) for numerous coherent digital modulation schemes, are derived and examined in terms of FHF. To gain further insight into the system performance, asymptotic closed-form expressions for the ASEP and OP are derived and interesting observations are made. Particularly, our asymptotic analysis reveals that the achievable diversity order for high SNR values depends essentially on the branches{\textquoteright} number. The proposed mathematical analysis is assessed and corroborated by Monte-Carlo simulations using computer algebra systems, while the PDF and CDF are validated further with the aid of the Kullback-Leibler divergence criterion and Kolmogorov-Smirnov test, respectively {\textcopyright} 2020.

	abstract = {The Gaussian Q-function (GQF) and its integer powers are quite versatile in various fields of science. In most applications, it is involved in intractable integrals for which closed-form expressions cannot be evaluated. In this paper, six new bounds for the GQF are presented and their tightness and simplicity are discussed compared to existing ones. As an application, these bounds can be efficiently used to evaluate in closed-form upper bounds for the average symbol error rate for various modulation schemes, in the presence of a generalized fading channel whose probability density function can be written as a summation of a particular Bivariate Fox{\textquoteright}s H-functions. α-μ, κ-μ shadowed, and M{\'a}laga distribution models have been considered as particular cases of such distribution. To gain more insight into the system reliability, asymptotic closed-form expressions for the system{\textquoteright}s ASER over the above fading models are further derived and interesting discussions on the key fading parameters{\textquoteright} impact are made. Numerical results and simulations reveal the tightness of the proposed bounds compared to previous ones, while they keep almost the same complexity. {\textcopyright} 2013 IEEE.},

	abstract = {This paper inspects the error rate and the capacity performance of a dual-hop energy harvesting (EH)-based fixed-gain amplify-and-forward relaying communication system, subject to fading impairments. We consider a source node (S) communicating with a destination node (D) via a relay node (R) equipped with a finite-size battery, which harvests energy from its received signal from S and uses it to power up its communication with D after amplification. Time-switching protocol is examined in the analysis for EH. In addition, the S-R and R-D hops are modeled by the Nakagami-m and $\alpha-μ$ fading models, respectively. A closed-form expression for the cumulative distribution function of the end-to-end signal-to-noise ratio is derived, based on which novel exact and asymptotic closed-form formulas for the average symbol error rate and average channel capacity are derived. The derived expressions are validated through Monte Carlo simulations. {\textcopyright} 2020 IEEE.},
