Embodiment Construction
[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0031] The underwater routing method of the present invention is described in detail from three aspects: energy loss model, layering stage and transmission stage.
[0032] The energy loss model gives the energy consumption generated by data transmission, and optimizes the hierarchical structure through energy control to avoid the exhaustion of node energy; Layer structure, ordinary nodes are in multiple different sink node hierarchical structures; in the transmission phase, the source node selects the forwarding node through a certain strategy to send data to the target sink node.
[0033] Energy loss model: Communication in underwater environments is heavily affected by factors such as water temperature, chemical composition, and water depth. Through the study of the communication path of two adjacent nodes, the energy loss model is formally defined as:

The invention discloses an underwater sensor network routing method of a plurality of mobile convergent nodes. The underwater sensor network routing method comprises a layering phase and a transmission phase, wherein in the layering phase, each convergent node forms a layered structure at the center; in the transmission phase, a source node transmits data to a target convergent node according to the nth layered structure of the convergent node s. The source node transmits the data to a next-hop forwarding node by two policies; the next-hop forwarding node transmits the data by using the same manner until a data packet is successfully sent to the convergent nodes. According to the underwater sensor network routing method, the policies are selected through the target convergent node so that the length of successively sending the data packet to a path can be effectively reduced, and furthermore, the energy consumption is reduced. The forwarding node selection policy optimizes a transmission path so that the deliverability rate of the data packet is improved.
Description
technical field [0001] The invention belongs to a routing method for an underwater wireless sensor network, in particular to a routing method for an underwater sensor network with multiple mobile convergence nodes, which is applicable to a network with multiple mobile convergence nodes. Background technique [0002] The underwater sensor network can provide better technical equipment and information platforms for activities such as marine environmental management, resource protection, disaster monitoring, marine engineering, and offshore production operations. Therefore, the underwater sensor network has received great attention from government departments, industries, academia and scientific research institutions all over the world. The sea network Seaweb research project hosted by the U.S. Office of Naval Research and the Air Sea Warfare System Center began actual underwater networking experiments as early as 1998. In recent years, more universities and research structure...
