Abstract:

Marine internet is an extension of the internet in the marine environment.Marine internet is very different from the existing terrestrial internet and needs extensive and in-depth research.Several common network structures in the marine internet were summarized and compared.The existing marine internet services are mainly provided through maritime satellites.Therole of shore-based networks,underwater acoustic communication and underwater acoustic networks in the Ad Hoc networks of the sea were introduced,and how to apply wireless Ad Hoc network technologies to the marine internet was introduced,such as ship Ad Hoc networks,aviation Ad Hoc networks and underwater Ad Hoc networks.From the multiple perspectives of air,water,and underwater,the advantages and disadvantages,limitations,and future development trends of many different networking technologies were analyzed,and possible future networking strategies for the marine internet were proposed .

Key words: marine internet, maritime satellite, underwater acoustic communication, Ad Hoc network
