Issue:

Several people (or systems, why not?) who are in the open sea, do not have the possibility of having access to the Internet, and the satellite connection is an option but it is a very expensive possibility.

Solution:

We propose a feasible and economical method so that people who are in this situation may be able to enjoy the use of the network.

We propose to reuse the existing meteorological buoys in the oceans, being equipped when necessary with the following components:

• Solar panel: Main source of energy that provides electricity to the other components of the buoy as well as allowing the batteries to be recharged.
• Rechargeable batteries: Provide energy when the conditions of sunlight and/or wind are not optimal.
• Wind generator: Alternative and parallel source of energy, which will provide electricity to the components with the advantage of providing greater autonomy and sustenance for cloudy or stormy days.
• GPS: In order to obtain the precise location of the buoys and as a tool to build new routes and / or relocations.
• Wi-Fi router: This component will be responsible for providing internet in a radius of xx kms. To achieve this, it will be connected to different satellites and/or other buoys, thus creating an extension of the signal.
• Sonar: In order to complement the Wi-Fi router and the repeater function, the device will communicate with others through a sonar, taking advantage of the environment in which it operates (the ocean) by extending the range of repeater coverage. Always taking into account to provide the minimum possible noise pollution for the sake of navigators and animals.
• Laser: Less information theft as it focuses directly on the buoy that you want to connect, previously located using the sonar. Among the main advantages: greater coverage and transfer speed.
• Software: Developed with artificial intelligence to make “intelligent decisions” in cases of “very” proximity to other buoys; as well as not to interfere with the usual routes of the boats.

In turn, a buoy can be configured and/or connected to existing ones by creating an extension (repeater) of the signal.

We also consider it necessary for buoys to behave intelligently so that they do not interfere with the oceanic routes of ships, as well as reduce redundancy in the vicinity of buoys.

At the same time, we believe it is necessary that before maritime accidents (oil spills, crashes between ships, etc.) buoys can generate alerts to competent authorities.

Considerations:

In order to see which would be the "optimal" locations to locate and/or relocate the buoys we have taken into account the following maritime maps:

1. On the map, a summary of the number of sea routes is shown and the number of annual frequencies is classified. Light colors are the routes with the highest traffic and dark ones are the ones with the lowest traffic of ships.
2. We also consider ocean currents.
3. Components and Technologies
   1. Weather buoys: The idea is to reuse and / or modify to take advantage of already integrated components.
   2. Sonar: Before talking about communication protocols, it is important to consider in what context the technology we are going to use will work, not only to know strengths and weaknesses, but also to take precautions. The sources are many and have many properties to consider, here are some of the most outstanding sources and properties:
      1. Propagation of Sound in Water: 1493 m / s (at 35C), 1505 m / s. (at 22C)
      1. Propagation of Sound in the air: 343 m / s (at 20C)
      2. Physical phenomena that affect the propagation of sound: transmission, absorption, reflection, refraction, diffraction or dispersion, diffusion.
   3. Profibus: This protocol allows the use of more repeaters without attenuation.
   4. Laser:

Repair and Maintenance

The buoy will have a system which will be maintained after a period of more than 5 years.

Future plans

In the first instance, the buoy will only serve to take internet to the ocean, we have planned that in the near future, the buoy will also have sensors that let you know how polluted the ocean is. They could also be used to gather oceanic information and learn a little more about the world in which we live.
