In this paper, we consider the secrecy outage probability (SOP) of a cooperative non-orthogonal multiple access (NOMA) vehicular communication (VC) system, where relay is working in either half-duplex (HD) or full-duplex (FD) mode. We assume that all these links experience Nakagami-m fading. Some closed-form analytical expressions for SOP performance FD/HD NOMA-VC system are derived. Results show FD-based superior than HD-based low signal noise ratio (SNR) region, and can be further improved...
It is challenging to accurately mode the local and global context during complex scene segmentation. To solve this problem, a semantic segmentation network contains self-attention module feature alignment proposed in paper. The designed combine features, which transformer backbone treats all patches equally scope, extract high-level features. improved masked with (MtFAM), combines form new decoder structure, fuse features obtained from vision module. Experimental results demonstrate that...
High-speed railway (HSR) wireless communications are required to ensure strict security. In this work, we study the secrecy performance of a nonorthogonal multiple access- (NOMA-) aided HSR communication system in case an eavesdropping user. Specifically, applying NOMA technology can effectively improve data rates. Therefore, downlink under communication. particular, exact analytical results for outage probability (SOP) based on no small-scale channel state information (CSI) derived. We also...
The line loss is an important economic and technical index to evaluate electricity power enterprise production management, according the nature it can be divided into theoretical management loss.Management caused by metering equipment error or poor management.Currently, stealing becoming more high-tech,committing method hidden , renovating means constant, which brings great difficulty work of anti-stealing.In that case,anti-stealing situation significant.In view above problems, this paper...
Information security is the basis of economic development, information construction, and protection people’s national interest. In this paper, performance reconfigurable intelligent surface (RIS)-assisted mixed dual-hop free-space optical-radio frequency (FSO-RF) communication systems studied analyzed to ensure safe transmission information. scheme, it assumed that atmospheric turbulence in fading FSO channel follows exponentiated Weibull distribution model RF Rayleigh model. Based on...
As promising industrial embedded networks, Controller Area Networks with Flexible Data-rate (CAN-FD) are widely used in time-sensitive domains, such as automotive networks. However, the absence of built-in security mechanisms CAN-FD necessitates development protection mechanisms. The existing Lightweight Authentication for Secure Automotive (LASAN) framework focuses on enhancing CAN/CAN-FD communication but neglects conflict between and delay. In this study, we conduct a thorough analysis...
Wireless sensor networks (WSN) are widely utilized in all walks of industries, and node localization is still essential as one the fundamental functionalities. Moreover, marine predators algorithm (MPA), swarm intelligence optimization algorithms, has proven to possess strong search capability high convergence speed. Therefore, for poor ability least squares method DV-Hop method, a reconstructed predator with adaptive enhancement (RMPA-AE) WSN proposed this paper. Firstly, population...
