英文摘要： With the growing importance of the maritime strategy, basic and applied research around underwater acoustic sensor networks is becoming more urgent. In recent years, the underwater mobile node is widely used in activities like marine scientific research and production. New requirements for existing sensor network based positioning method is proposed aimed at demand for locating and tracking for mobile node. In the above application background, the project intends to carry out research of key technologies of mobile node positioning based on underwater acoustic sensor network, the main contents are: 1 The algorithm research of method of time of arrival based joint time synchronization and tracking (TOA-TS) used in ranging underwater positioning ; 2 Underwater sensor network positioning method with mobile node based on factor graphy; 3 Collision avoidance research of ranging signal in underwater sensor network localization; 4 Research of redundant preferred method of underwater sensor network nodes; 5 The research for collaboration positioning of underwater sensor networks. Through these studies, the project would like to construct a set of underwater acoustic sensor network localization demonstration platform.
