DS-SWIPT: Secure Communication with Wireless Power Transfer for Internet of Things

Abstract

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.
