Abstract :
The measurement of CTD is the key of oceanic research. The conventional methods have lots of limitations. Ad hoc wireless sensor network is built from sensor nodes that may spontaneously create, assemble themselves, dynamically adapt to manage movement of sensor nodes, which is most suitable to the CTD measurement. The positions of CTD sensors detected by GPS are changed by waves, which leads to the changes of network topology and may increase the energy consumption. Two steps are taken to enhance the life of the network. First is the adoption of energy efficient routing protocols based on rCAMP. Second is the data compression. Then data are transferred to control center and processed by B-spline algorithm to build the ocean CTD model
