Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] see Figure 1 to Figure 4 As shown, the present invention is an access protocol method based on an unmanned ship. According to the motion state of the unmanned ship, the method designs different access protocol methods, which are respectively unmanned ship mobile mode and fixed mode protocol method.

[0018] Aiming at the scenario where the unmanned ship performs data recovery during the movement process, the mobile mode protocol method is designed, and the structure diagram of the unmanned ship mobile recovery data network, as shown in figure 2 As shown, the network topology changes with the movement of the unmanned ship. The underwater acoustic nodes that are within the communication range of the unmanned ship and have data transmission transmit monitoring data to the unmanned ship in a single-hop manner. The mobile mode access protocol meth...

Abstract

The invention relates to a method for dynamically accessing an underwater acoustic communication network protocol based on an unmanned ship. Different protocol access methods: unmanned ship moving mode and fixed mode protocol methods are designed for different application scenes of the unmanned ship. The unmanned ship moving mode protocol method is a hybrid protocol based on the moving features of the unmanned ship. In a refresh recombination stage, a random competition protocol is employed, the unmanned ship is taken as a cluster head, and underwater acoustic nodes send J / L / S signals to the unmanned chip for appointment, a cluster is refreshed and recombined. According to the unmanned ship fixed mode protocol method, the communication distance strength is taken as the basis, the communication energy consumption and recycle information quantity are taken as performance measurement indexes, and the influences of different underwater acoustic communication capabilities, node access modes, protocol data transmission cycles and unmanned chip navigation paths on the underwater acoustic monitoring network data recycling performance are determined. According to the method provided by the invention, the new thinking and protocol access design method for recycling underwater acoustic monitoring network data is provided, and the data is recycled autonomously and wirelessly.

Description

technical field [0001] The invention belongs to the technical field of network communication, and in particular relates to a protocol design method for an unmanned ship to dynamically access an underwater acoustic communication network. Background technique [0002] With the rise of unmanned platforms and the maturity of related technologies, unmanned ship platforms have gradually become a hot spot in marine technology research and development. In the past ten years, more than 40 marine research institutes in more than 10 countries have developed unmanned ships for different purposes. The applications include environmental monitoring, marine surveying and mapping, underwater and underwater communication relay, etc., and mainly carry out automatic control for marine research objects. , data processing, etc. Although unmanned ships are greatly affected by the marine environment, with the development of related technologies, the development of basic drive control of unmanned s...
