“…According to the different processing of the relay for the forwarded signal, collaborative communication can be divided into decoding forward, amplifying forward, and coding collaboration. The advantage of decode-ahead transmission is that it has low complexity and the relay requires only simple hard judgments, which can eliminate the accumulation of background noise and achieve good performance at high signal-to-noise ratios [6]. However, when the relay is unable to correctly adjudicate the source signal, its forwarding signal can cause an error propagation effect, which affects the diversity gain of the system.…”

Network security protocol (NSP) TT has become a hot topic of research nowadays. This paper researches NSP testing technology(TT) based on Wireless Communication System(WCS), briefly analyzes wireless collaborative communication methods and NSP TT, including encryption and signature protocols and network security communication protocol execution process; designs an adaptive black-box testing method for stream cipher and group cipher, which are commonly used in wireless communication networks, and uses the designed testing scheme to design The test system and cryptographic test system architecture of wireless communication NSPs are designed using the designed test scheme, and the implementation of the system is modularized and the corresponding test results are analyzed. The results of the experimental tests show that the NSP testing technique based on WCS is feasible.

“…A wide range of critical issues related to WSN application in SHM was discussed by Wang et al [ 419 ], including sensor integration, sampling frequencies, transmission bandwidth, real-time capability, and frequency of wireless transmitters. A study conducted by Fu et al [ 420 ] examined the impact of wireless communication technology known as GPRS (General Packet Radio Service) on hydraulic engineering NDT techniques. Zhang et al [ 421 ] proposed a novel passive wireless sensor based on ring dielectric resonators for position-insensitive crack monitoring.…”

This paper reviews recent advances in sensor technologies for non-destructive testing (NDT) and structural health monitoring (SHM) of civil structures. The article is motivated by the rapid developments in sensor technologies and data analytics leading to ever-advancing systems for assessing and monitoring structures. Conventional and advanced sensor technologies are systematically reviewed and evaluated in the context of providing input parameters for NDT and SHM systems and for their suitability to determine the health state of structures. The presented sensing technologies and monitoring systems are selected based on their capabilities, reliability, maturity, affordability, popularity, ease of use, resilience, and innovation. A significant focus is placed on evaluating the selected technologies and associated data analytics, highlighting limitations, advantages, and disadvantages. The paper presents sensing techniques such as fiber optics, laser vibrometry, acoustic emission, ultrasonics, thermography, drones, microelectromechanical systems (MEMS), magnetostrictive sensors, and next-generation technologies.

“…At the same time, because the original cutoff wall is plastic concrete wall, its strength and deformation performance are low [ 7 ]. Therefore, in the construction process of highway widening and the original cut-off wall, the field real-time monitoring of the original cut-off wall and the new construction internal force [ 8 ], deformation [ 9 , 10 ] and stress [ 11 , 12 ] changes, and the appropriate construction optimization measures [ 13 ] are given according to the monitoring and analysis results to ensure the safety and stability of the original cut-off wall. The field monitoring and analysis of the cutoff wall in Daning Reservoir is a typical geotechnical safety monitoring and analysis.…”
