Underwater Wireless Communication Seminar ppt and pdf Report

The signals that are used to carry digital data via underwater channel are the acoustic waves because they can spread over long distances and the radio signals as electromagnetic waves are not used because they spread over short distances. From the past many decades, cabled submersibles were used to discover the titanic and hydrothermal vents, cabled submersibles played a major role in the underwater communication and to overcome the problems in those, the underwater wireless communication came into existence.

The necessity of Underwater Wireless Communication:

The wired underwater communication is not practicable in the following cases:

  • Temporary cases
  • Breaking of wires
  • Significant costs of deployment
  • Experiment over long distances

To overcome all the above limitations the underwater wireless communication came into existence and thus, there was the necessity of the underwater wireless communication.

The technology used in Underwater Wireless Communication:

At, present we are using the wireless technology and the underwater wireless technology is a farthing to imagine; but the researchers are working on it and in the underwater wireless technology the acoustics waves are used instead of electromagnetic waves. The acoustic channels have the following characteristics:

  • Frequency-dependent propagation loss
  • Severe multipath and
  • Low speed of sound propagation

When a signal is propagated through acoustic channel then it is received by the receiver through a direct path or surface reflection or bottom reflection and this happens due to ray bending of the acoustic waves. The acoustic modem applied science offers two types of modulation and they are as follows:

  • Frequency shift keying (FSK) with coherent detection
  • Phase shift keying (PSK) with non-coherent detection

With the development in the acoustic modem applied science, sensor applied science and vehicular applied science the ocean engineering is moving towards integration of these tools into autonomous networks. As per the applications, the underwater network topologies are two types and they are as follows:

  • Centralized network topology and
  • Decentralized network topology

Applications of the Underwater Wireless Communication:

The applications of the underwater wireless communication are as follows:

  • In the coming days, the applications could increase from myriad industries ranging from the offshore oil company to aquaculture and fishing industries.
  • It is also used in pollution control and climate recording.
  • It also has the application in the detection of the objects on the ocean floor.
  • Underwater wireless communication is also used in environmental monitoring and collecting of oceanographic information.
  • It has the application in marine archaeology, search and rescue machines and defense.
  • It is also used in seismic monitoring, pollution monitoring and ocean currents monitoring.
  • The underwater wireless communication is used in the equipment monitoring and control and also in the autonomous underwater vehicles (AUV).
  • It is also used in remotely operated vehicles (ROV).
  • It also has the application in the acoustic navigation technology for multiple autonomous underwater vehicles.
  • It is used in solar-powered autonomous underwater vehicles.

Advantages of Underwater Wireless Communication:

The advantages of the underwater wireless communication are as follows:

  • Underwater wireless communication avoids the data spoofing.
  • It avoids the privacy leakage.
  • It has the parameter of monitoring the pollution.

Disadvantages of Underwater Wireless Communication:

The disadvantages of the underwater wireless communication are as follows:

  • The available bandwidth of the underwater wireless communication is very limited.
  • The channel characteristics of the underwater wireless communication including the long and variable propagation have the delays.
  • It has the multipath issues and fading problems.
  • It has the high bit error rate.
  • It has the limited battery power and the batteries cannot be recharged.
