The study of Underwater Wireless Networks as a research field has grown significantly in recent years offering a multitude of proposal to resolve the communication between the nodes and protocols for information exchange networks. Acoustics has been used by nature for years to communicate in the underwater environment using it as a language, dolphins and whales for instance are able to use it to send information between their groups. The first reference to the underwater sound propagation can be found in what Leonardo Da Vinci wrote in 1490: "If you cause your ship to stop and place the head of a long tube in the water and place the outer extremity to your ear, you will hear ships at a great distance from you".
