Abstract

The invention relates to the technical field of wireless communication, and discloses a matrix coding and multi-hop link state sensing routing protocol suitable for underwater acoustic communication, which comprises the following steps of: initializing each node, and collecting own basic information of each node; each node periodically sends information messages which exist in a hop-count hierarchical coding matrix form and are used for information exchange to neighbor nodes so as to preliminarily construct a network topology view of each node; integrating and perceiving the network topology view of each node so as to form a network topology database of each node; finding a routing path between the source node and the destination node according to a preset rule for dynamic query; carrying out data transmission based on the queried routing path, and monitoring a link state and a state of a one-hop neighbor node of the node to be subjected to data transmission in real time in a data transmission process; judging whether the receiving node receives the data sent by the sending node or not; and judging whether the sending node receives the confirmation message. According to the invention, the convergence of the routing table can be quickly completed.
