A reliable method of wireless communication of robotic systems based on data threshold separation

Abstract

The paper considers a reliable method of data transmission in communication systems and control of robotic complexes. Due to the fact that a change in part of the encoded information transmitted through communication channels can lead to partial or complete loss of data and, as a consequence, lead to loss of control over the robotic complex. Therefore, it is necessary to apply methods of protecting data transmitted over radio channels. The proposed method is intended to ensure the protection of information in the communication channels of robotic complexes from the access of unauthorized users and to confirm the reliability of the information received. The article examines data protection methods designed to protect information circulating in systems formed by several interacting agents. The approach under consideration is based on the methods of information protection and error-correcting coding based on the system of residual classes. The applied methods of error-correcting coding, based on the system of residual classes, are based on the idea of threshold data separation, in which the original information can be restored from parts of the original information. This is due to the fact that redundant modular arithmetic, or redundant system of residual classes, has unique properties with respect to error detection and correction. In addition, the system of residual classes has such an advantage as low computational complexity of data separation algorithms. To increase the reliability of communication between robotic complexes in multichannel communication systems, the paper proposes a method for information protection and noise-resistant coding, based on a multistage threshold data separation. As a result of the work, a system of noise-resistant information transmission was obtained, which provides comprehensive protection for robotic systems.
