The improved differentiated data transmission scheme in wireless sensor networks

Abstract

Wireless sensor networks are widely used in environmental monitoring, military reconnaissance, industrial control and other fields, but their communication links generally have problems such as packet loss, interference and node failure, which are difficult to meet the requirements of accurate and efficient data transmission at the same time. In view of this contradiction, this study proposes an improved differentiated data transmission scheme MR-RDCM based on robust Chinese remainder theorem, and applies it to wireless sensor network scenarios. The scheme differentiates the data according to value, encodes the important data as the main value in the remainder system, and embeds other data into the same transmission unit. In this paper, the data embedding and reconstruction process for wireless sensor network is designed, the correctness and characteristics of the algorithm are analyzed, and the experimental implementation is carried out according to the actual environment, and compared with the existing methods. The experimental results show that the new method can not only maintain the complete and accurate transmission of important data, but also significantly reduce the transmission delay and achieve near optimal bandwidth efficiency. It provides a differentiated transmission scheme with both reliability and efficiency for resource constrained wireless sensor networks.
