“…In this section we presents graphically results obtained from equations ( 3), ( 5) and (7). The parameter values used to obtain the results are defined in the paper [31] for the case when we consider moderate atmospheric turbulence for the Málaga model and the pointing error between the transmitter and the receiver is negligible.…”

The evolution of technology and the internet led to the opening of infinite ways to engage with consumers worldwide. The idea of everything taking place online is now applicable for the finance and banking sector as well. The system of online wallets and e-transactions have become very common as a mode of payment. But handling money on a network is also dangerous as hackers may break into the firewall. The security wireless communication in e-commerce has received extensive attention recently. This paper offers an analytical framework to investigate the eavesdropping attacks over wireless communication link. Eavesdropping attack, as one of typical security threats in wireless communication systems, has attracted considerable attention. We will observe the physical layer security of an arbitrarily dimensioned wireless network in the presence of an unauthorized attacker. In this paper, we will explain different models of eavesdropping and attacks. Also, we will consider basic performance of the system such are secrecy outage probability (SOP), strictly positive secrecy capacity (SPSC) and average secrecy capacity (ASC) based on a probability density function (PDF) and specific cumulative distribution function (CDF).

.In free space optical (FSO) communications systems, the signal fading caused by atmospheric turbulence is a slow fading, so adaptive transmission technology can effectively mitigate the problem of channel fading. Considering the combined effects of turbulence, attenuation, and pointing errors on the atmospheric transmission of laser signals, we proposed an adaptive M-ary phase shift keying subcarrier modulation algorithm based on power control and studied the combined adaptation of modulation size and average transmit power. Karush-Kuhn-Tucker conditions are used to solve the optimization problem of maximizing the throughput under the constraint of average transmit power, the expressions of throughput and outage probability are derived based on Meijer G-function. We finally evaluated the effects of turbulence intensity, beam waist radius, jitter standard deviation, weather conditions, and maximum modulation order on the throughput and outage probability of adaptive system.

“…As the most generalized model for the FSO link, Malaga model has been widely studied, the performance of Malaga link considering pointing error is studied [19]. [20] has investigated average capacity of Malaga link with pointing errors when adaptive transmission is adopted. [21] proposed a novel indirect diffused light FSO system in vehicular networks, high speed data transmission is realized.…”

We conduct a research on free space optical (FSO) communication system that is applied for transmission in wireless sensor networks (WSN), which is based on the hybrid pulse position modulationbinary phase shift keying-subcarrier intensity modulation (PPM-BPSK-SIM) undergoes novel Exponentiated Weibull fading channels. When battery-charged sensor transmission nodes with limited energy is transmitted, it is vital to study the performance of the transmission link. We have derived the exact joint probability function of the transmission link when the atmospheric turbulence and pointing errors are considering. On the basis of them, the unconditional average bit error rate (BER) for hybrid PPM-BPSK-SIM is derived, then the closed expression of the outage probability and the average channel capacity are also derived. Research results indicates that increasing the receiver aperture by aperture averaging effect can distinctly improve the performance of the link. Additionally, for any circumstances of atmospheric turbulence and pointing errors, by combining the utilization of hybrid PPM-BPSK-SIM modulation and symbol with average length greater than eight, the average BER performance can be conspicuously enhanced. The outage probability and average channel capacity of the FSO link are jointly affected by atmospheric turbulence and pointing error, and optimization strategies in different scenarios are given by our research.
