Do you know around two-thirds of the earth’s surface is shielded by water?
Not only that, water has a crucial part to play in the existence of life on earth, without it, we cannot survive. Besides, it plays an integral part in our economic balance. Some of the major verticals that are interconnected with water are oil, gas, fish, tourism, shipping etc.
Along with the growing application of Internet of Things scientists are looking for ways to manifest Internet of Things (IoT) in underwater with the help of degrading radio waves to communicate over the vast area under seawater. Underwater acoustic communication already has been used to keep a strict eye on security parameters.
Light is an important parameter to make underwater Internet of Things (IoT) to work. Underwater optical communication methods were suggested by Researchers of King Abdullah University of Science and Technology (KAUST) in Thuwal,, Saudi Arabia. The team is now investigating parallel light-wave information along with power transfer (SLIPT) settings, in order to transmit energy and data to the electronic devices kept underwater.
Recently the team have announced an advanced experiment where they successfully achieved underwater two-way transmission data with power over 1.5 yards between a receiver and a sensor-equipped with the solar panel.
According to the team, the SPLIT system will be preferred over wires strung as this system is less prone to error than manual signals. Also, there will be lesser chances of audible confusion than ultrasound voice communication. Till date divers still prefer to communicate via hand gestures.
According to Joes Filho a researched in KAUST, SPLIT can charge devices in remote locations where continuous powering is expensive and challenging. He was also involved in developing the laser project; believe ships and boats on the surface water communicate through optical communication to underwater vehicles through IoT sensors on the ocean floor. The lasers can communicate through underwater robots at the same time. Return communication data is transferred to the surface vessel to communicate with land bases or data centres via Radio Frequency (RF).
Flying drones can be used to inject power to the seabed surface and simultaneously can receive data; that’s what researchers believe.
The school also explains that more development requires performing prior to the operation of SPLIT. According to Abderrahmed Trichili, the co-first author, underwater optical communication provide a massive bandwidth which is useful for securely communicating information over a long distance.
KAUST has been set up on the Red Sea coast to explore the technical background of that are for years. It was also involved in developing early underwater data communication which was record-breaking. In 2015, it recorded a 16-QAM-OFDM transmission with 450 –nanometre laser in a 4.8 gigabit per second. The main reason behind using Orthogonal Frequency Division Multiplexing or OFDM is it can split single data stream into multiple channels in order to minimize the interference.
Gradually seas, oceans and other large water bodies are becoming extremely crucial for data centres, as great swaths of the world’s population are found mostly near coasts instead of inland. The researchers have noticed a shift towards top-notch computing that keep resources close to the data. There is also a requirement of computing cooling that can be obtained by ocean water. Another technique of powering servers is wave energy that reflect data communication and sea are becoming integrated.
In 2018, Microsoft launched an undersea water-cooling data centre, below 117 feet of the surface water. Another equipment, garden-hose-sized cables handle all the underwater internet traffic, covering a smaller area to a massive region like across oceans and between continents. So, it is not a new invention, so many technologies are there to leverage the power of the Internet of Things (IoT) underwater. Through various ways, ocean-based computing is being explored, but no rent system or jurisdictional ownership is there especially on the high sea.
