Are sensors smart?
A smart sensor is a device that takes input from the physical environment and uses built-in compute resources to perform predefined functions upon detection of specific input and then process data before passing it on. A smart sensor might also include several other components besides the primary sensor.
How are wireless sensors used in the underwater environment?
Technique of sending and receiving message under the utilization of sound propagation in underwater environment is known as acoustic communication. Underwater sensor networks have number of vehicles and sensors that deploy in a specific area to perform collaborative monitoring and data collection tasks [1].
How are underwater networks different from terrestrial networks?
Basically communication in underwater environment is different from terrestrial networks due to its unique features of the networks. Underwater Networks are established by using acoustic signals as communication medium with the help of sensors and autonomous underwater vehicles.
What are the factors that affect underwater communication?
In this paper, a survey of UWSN regarding underwater communication channel, environmental factors, localization, media access control, routing protocols, and effect of packet size on communication is conducted.
How are oceanographic sensors used in the ocean?
Traditionally for the monitoring of ocean bottom, oceanographic sensors are deployed for recording data at a fix location and recover the instruments at the completion of task.
