The invention relates to a reliable data transmission method and system applied to an underwater acoustic network, comprising the following steps: acquiring the current packet error rate of data transmission among nodes of the underwater acoustic network and the average packet error rate of historical data transmission; according to the current packet error rate and the average packet error rate,calculating a theoretical packet error rate; according to the theoretical packet error rate, calculating a code rate; and performing the data transmission among the nodes by utilizing the code rate. The technical scheme provided by the invention has the advantages that the theoretical packet error rate is calculated by virtue of the historical average packet error rate and the current packet errorrate, then the code rate is calculated according to the theoretical packet error rate, and the data transmission is performed by virtue of the code rate, so that data can achieve high delivery rate and data transmission delay is small.
Description
technical field [0001] The invention belongs to the field of underwater acoustic networks, in particular to a reliable data transmission method and system for underwater acoustic networks. Background technique [0002] Underwater acoustic communication networks (UAN) have the characteristics of long propagation delay, error-prone channel and communication based on half-duplex acoustic modem. These characteristics pose challenges to reliable data transmission in UANs. Specifically, we consider a multi-chord topological network with one sender and one receiver. This type of UAN is widely used, such as sending important data from the underlying nodes to the surface gateway site. [0003] In the traditional end-to-end and hop-by-hop reliable data transmission process, due to the error-prone channel and high retransmission probability, the transmission efficiency is low. Due to the large propagation delay in underwater environments, each retransmission results in a significant...
