The Researches on Node Localization Algorithm and Self-Organization Process in UASNs

With the problem of sparse anchor nodes in underwater acoustic sensor networks,a distributed node localization algorithm is put forward.In order to provide the information for node localization algorithm such as the neighborhood relation tables,a distributed and concurrent data transmission algorithm is presented which includes a conflict solving strategy dealing with the communication conflict during the data transmission process.Simulation experiments demonstrate the feasibility and validity of localization algorithm by using these combined methods.
