Ship's Internet of Things is an important part of ship's automatic control system.Mesh wireless network un-dertakes the task of data transmission in the Internet of Things.In this paper,the load rate regulation scheme of ship commu-nication channel is studied.In the data transmission of Mesh wireless network,there are three schemes:static channel alloca-tion,dynamic channel allocation and mixed channel allocation.The mixed channel allocation is more suitable for ship Inter-net of Things data transmission.DACA-LB channel load rate regulation algorithm is designed,the implementation process of the algorithm is analyzed,and the advantages and disadvantages of DACA-LB algorithm and ORPTD algorithm are com-pared in terms of data transmission delay and throughput.The results show that DACA-LB algorithm is better.
