Design of Automatic Identification System for Enclosed Waters Based on LoRa

Abstract

Considering the movement characteristics of ships in closed waters and the requirements of water traffic supervision, a new ship identification system is designed by using a wireless ad hoc network technology wide area Internet of things. The working principle, system structure, system composition and the realization of the system are described. An adaptive communication rate algorithm for shipborne units is established to reduce the system communication delay and bit error rate (BER). A spectrum allocation model based on game theory is proposed to improve the channel utilization and throughput of the system. The simulation and experimental results show that the communication mode of the system is flexible and convenient, the data transmission is reliable, and the system can meet the requirements of automatic identification of ships in closed waters. It can be widely used in ship navigation and safety supervision in closed waters.
