Abstract

The present invention discloses a hierarchical time-division multiplexing link state underwater acoustic network networking method, belonging to the technical field of underwater acoustic networks. It includes network deployment, network initialization, network configuration, network withdrawal and network access processes. Among them, network deployment refers to the state test and parameter injection process before the underwater nodes are deployed. The network initialization stage completes the interaction of link state descriptors between the central node and multi-layer neighbor nodes and the improvement of the link state database. Network configuration is that the central node adjusts some non-optimal routing table entries during the initialization process. The network access and network withdrawal processes describe the processes of nodes joining and exiting the underwater acoustic network. By node stratification, the present invention effectively reduces the link state update packets frequently transmitted during node initialization, speeds up the convergence speed of the underwater acoustic network topology, and can improve the operation efficiency of the underwater acoustic network.
