Internet of Things (IoT) is promptly spreading and reaching a series of domains, including many industrial applications designed for monitoring purposes. In such networks, sensitive information is being collected and transmitted by IoT devices with limited resources, which leads energy efficiency and cybersecurity to become critical. Therefore, this paper proposes a novel approach for wireless communications and power for IoT monitoring applications with the aim of achieving energy efficiency and security. The proposed solution combines the advantages of Simultaneous Wireless Information and Power Transfer (SWIPT) for wireless power transfer to remote IoT devices and Direct Sequence Spread Spectrum (DSSS) for data confidentiality. The proposed DS-SWIPT is a security improvement over the original SWIPT. Simulation results show that the proposed DS-SWIPT can achieve energy efficiency along with acceptable data confidentiality.

“…However, in the context of the rapid evolution of communication technology, military communication must have stronger confidentiality and anti-interference. Spread spectrum technology has attracted extensive attention, and DSSS has been the most widely used spread spectrum method at present (Sajid et al, 2019). In military communication, there has been considerable research on common chaotic mappings in the context of spread spectrum technology.…”

With the rapid development of wireless communication technology and the increasing demand for communication quality in various fields, spread spectrum communication (SSC) and multiple input multiple output (MIMO) technology have become crucial research directions in the field of military communication, and space-time block coding (STBC) is an indispensable key technology in MIMO systems. This paper combined the excellent instrument interaction ability of LABVIEW and the data processing ability of MATLAB to build a direct sequence spread spectrum-space time block coding (DSSS-STBC) model based on circular mapping (CM) spread spectrum code, aiming at realizing multi-domain joint transmission of information in space, time, and power domains. The results demonstrated that the joint simulation platform of LABVIEW and MATLAB/Simulink successfully confirmed the superior spread spectrum performance of chaotic spreading codes based on circular mapping compared to traditional spreading codes. In addition, the multi-domain joint coding combining DSSS and STBC significantly enhanced the reliability and interference resistance of the communication system.
