* Question
| There are big differences between the underwater acoustic sensor network and the traditional wireless sensor network. What are the main aspects? |
* Answer
| 1) The UWSN node signal is affected by the obstacles of underwater obstacle blocking, antenna direction, transmit power, antenna gain, battery state and signal-to-noise ratio threshold. It is considered to have irregularity, that is, the communication range and perception of UWSN nodes.The range is irregular in different orientations.
3) The bandwidth of the underwater acoustic communication link is limited, and the transmission error rate is high.4) The UWSN node is easily moved by various external forces (such as water flow movement, water condition disturbance, underwater biological touch, etc.). |
