Multi-path coordinative communication method for underwater sound sensor network

The invention discloses a multi-path coordinative communication method for an underwater sound sensor network, belongs to the technical field of underwater sound communication, and aims at solving the problem that unstable point-to-point underwater sound communication in the underwater sound sensor network leads to increase network delay and even paralysis. The method is that different signals are transferred to the same collecting node through different relay nodes to obtain space diversity gain provided by different channels for receiving and decoding, and therefore, the reliability of underwater sound communication under the network environment can be improved. According to the method, the underwater sound physical communication technology and the route technology are combined by the cross-layer type protocol design method according to the application feature of the underwater sound sensor network, and meanwhile, the optimal selection of the reliable underwater sound communication and the relay node can be achieved, and therefore, the network protocol efficiency can be obviously increased.
