An automatic identification system based on the public wireless mobile IP network—MIP-AIS is put forward

to give a solution of the navigation and collisions of non-IMO Convention ships in the coastal and inland waterways

which will compensate the AIS based on VHF communications for the application limitations.Based on the research of the foundation principle and search algorithm in MIP-AIS

some key technologies are resolved about finding the "adjacent" ships by the public wireless communications

achieving the real time information transmission among the "adjacent" ships and minimizing the burdens on the wireless communications.The efficiency of the search algorithm and the bandwidth demand of data transmission are analyzed.The experiments show that the MIP-AIS is capable to realize the ship identification in coastal and inland waterways

the function and performance of MIP-AIS can satisfy the requirements of IMO international standards.
