A Neighbor Discovery Method for Frogman Underwater Wireless Optical Communication

Abstract

The invention provides a neighbor discovery method for underwater wireless optical communication of frogmen. The neighbor discovery method is specifically implemented according to the following steps:step 1. establishing node structures of neighbor discovery, and encoding each position on the node structures; step 2. sending, by an initiating node structure serving as a sending node, a request information frame; step 3: after a node structure to be discovered receives the request information frame, sending, by the node structure to be discovered serving as a receiving node, a response information frame; step 4, sending, by the sending node, an acknowledgement information frame after receiving the response information frame; and step 5, after the receiving node receives the acknowledgementinformation frame, indicating that the neighbor discovery process ends. According to the neighbor discovery method provided by the invention, the communication mode is flexible, the neighbor discovery requirements of underwater communication can be well adapted to, the surrounding frogman nodes can be discovered quickly and accurately, and a communication link is established with the surroundingfrogman nodes.

Description

technical field [0001] The invention belongs to the technical field of underwater wireless optical communication, and in particular relates to a neighbor discovery method for frogman underwater wireless optical communication. Background technique [0002] Due to military needs, frogmen are generally required to carry out underwater search, reconnaissance, blasting, and special combat missions. The tasks they shoulder are hidden and dangerous. When frogmen cooperate to perform tasks underwater, the environment is complex and changeable, and good communication needs to be maintained. To ensure mutual cooperation, so neighbor discovery when underwater frogmen communicate is very important. The existing communication methods mainly include underwater acoustic communication and radio communication, but in underwater acoustic communication, the sound wave has a large attenuation in the water, narrow bandwidth, slow speed, high energy consumption and large volume; the electromagnet...

AI Technical Summary

Problems solved by technology

The existing communication methods mainly include underwater acoustic communication and radio communication, but in underwater acoustic communication, the sound wave has a great attenuation in the water, narrow bandwidth, slow speed, high energy consumption and large volume; the electromagnetic wave method of radio communication mainly Using very low frequency communication, this method requires the use of a towed antenna several hundred meters long, and the communication rate is slow. This method is not high in concealment and is easily interfered, and cannot communicate in real time
