A kind of ship mobile ad hoc network system, networking method and working method

Abstract

The invention discloses an SMANET (shipping mobile ad hoc network) system, which comprises an SMANET and a plurality of AIS (automatic identification system) terminals communicated through the SMANET, wherein each AIS terminal is connected with the SMANET to realize the information interaction among the AIS terminals, a VHF (very high frequency) ratio station of the AIS terminals is set to be a physical layer of the SMANET, and an SOTDMA (self organizing time division multiple access) protocol of the AIS terminals is set to be an MAC layer of the SMANET. The invention also discloses a networking method of the SMANET and the work method of the SMANET. According to the characteristics of shipping formation networking communication, the minimum quantity of network control information is added into the existing AIS terminals, a heuristic method is used for analyzing the network control information, and the shipping formation network building and network maintenance processes are carried out, so that a ship provided with the AIS terminals has the self networking function, and communication link establishing, information interaction and mutual exchange of needed products with any AIS terminal in a shipping group can be realized.

Description

technical field [0001] The invention relates to the field of ship wireless communication, in particular to a ship mobile ad hoc network system, a networking method and a working method. Background technique [0002] With the rapid development of my country's market economy and global trade, maritime traffic has also developed rapidly, and the number and speed of ships have continued to increase, resulting in an increase in the density of maritime traffic, which puts forward new challenges for ship collision avoidance, port traffic management and navigation safety. Require. The automatic identification system (AIS) is a joint research achievement of the International Maritime Organization (IMO), the International Association of Aids to Navigation (IALA), and the International Telecommunication Union (ITI-R). AIS is a shipboard system that uses GMSK / FM modulation in the maritime VHF frequency band and transmits ship dynamic and static data such as ship position, speed, course,...

AI Technical Summary

Problems solved by technology

However, the AIS system only defines the data interaction strategy of the physical layer and the MAC layer, and the effective coverage of the network is limited to one-hop neighbor nodes. For large-scale ship formation collaborative replenishment, collaborative search and rescue and other application scenarios, it lacks the overall control and control of the top-level network.
