Underwater radiocommunications for optimized monitoring using multirelay devices

Underwater wireless communication links have up till now almost exclusively been implemented using acoustic systems. Underwater radio is the range limitation due to the tremendous attenuation is assumed as an unchangeable environmental element.

The interest in re-evaluating Electromagnetic (EM) Communications in Underwater Sensor Networks lay, first of all, in the increasing interest of industry, military, environmental operations, seaport management that is demanding reliable high rates for underwater links and acoustic communications show some important limitations that cannot cope with this kind of challenges. On the other hand, it is generally accepted that acoustic communications are unbeatable in deep sea water communications with remote sites, no power limitations and not high demanded data rates. However, our scenario is shallow waters (close to the shore in sea water or fresh water like rivers, dams or reservoirs) where acoustic systems show much worse performance. In our opinion, EM is the only alternative that makes sense in this scenario. And finally, a change of paradigm due to very important advances in different fields coming from new effective antennas, new considerations regarding the attenuation of alternative propagation paths and DSP developments.

We commit important contributions regarding:

  • The antenna design.
  • The propagation model.
  • Design of communication systems operating in the low power regime.
  • A new paradigm where we envision that underwater communications will be based on a set of numerous static devices and also UUV (Unmanned Underwater Vehicles) that permit saving the attenuation limitation using multihop communication protocols. Indeed, this network will be able to improve standard detection or estimation procedures by information fusion and distributed consensus / diffusion algorithms and will permit additional functionalities like selflocalization, tracking of moving vehicles and navigation guidance.
  • All these achievements will be carried out as a combination of theoretical contributions, measurement campaigns, modeling, and software and hardware developments. In fact, the main value of this project is the balance between all these aspects to ultimately create an operative Underwater Wireless Sensor Networks (UWSN) to be properly prototyped towards the technological transfer to interested companies.
