Research on WSN Secure Communication Method Based on Digital Watermark for the Monitoring of Electric Transmission Lines

Abstract

The wireless sensor network is arranged on the long-chain distributed electric transmission line for real-time monitoring of the electric transmission line. The safe transmission of the collected electric transmission line sensing data is a key issue to be solved urgently. Due to the low processing ability of the sensor nodes, conventional high-complexity security methods such as traditional identity authentication and tamper-proofing can extend the processing time of the node processor, which is unacceptable for real-time data. In addition, due to the high voltage of the electric transmission line, it is impossible to supply power to the wireless sensor nodes directly, and the traditional complicated safety methods have high energy consumption. Therefore, this paper proposes a WSN secure communication solution for electric transmission line based on digital watermark. The algorithm has less time overhead and meets the real-time requirements of WSN communication in electric transmission lines.
