Aiming at problem of serious energy loss in underwater wireless sensor networks（ UWSNs） and the phenomenon of irregular sensor node distribution

construct a new cone type UWSNs

setting each surface buoy nodes as the vertex

the sensor node can move according to energy

the active nodes and the backup node will be abstracted to binary tree structure

which simplifies topology control and routing transmission. Simulation test of algorithm is achieved by Matlab

and respectively discuss the different data packet delivery rate to 4 layers binary tree

6 layers binary tree 4 and 8 layers binary tree. The results show that the greater the number of layers have

the high the transfer rate is; then compare the algorithm for UWSNs with depth-based routing（ DBR） algorithm

it shows that this algorithm has high data packet transfer rate and low energy consumption.
