Researchers from the university of Buffalo have developed a new protocol was developed for the underwater transmission of data by sensor networks to laptops, smartphones and other wireless devices.
Used worldwide by organisations for nautical research acoustic waves for the communication with sensors that are located under water. Sensors on the seabed to send acoustic waves to the buoys, which they converted into radio waves and send it to satellites. That send the radio waves, then to computers in the country.
This works slow and cumbersome because every system has a different infrastructure, was Tommaso Melodia, the leader of a project at the university of Buffalo to a single framework. His team has managed to get sensors underwater directly, and in real time with laptops, smartphones and other mobile devices to communicate. In his research paper describes Melodia that the architecture is compatible with the tcp/ip protocol and ipv4 as well as ipv6 are supported. The stack would be on different operating systems are usable, and the existing onderwatermodems would be easy to adapt.
The optimization for onderwaterwerking is located in an adaption layer, between the datalink and the network layer is and for header compression and datafragmentatie. This would make networks much more resilient to the delay of signals underwater.
The framework is, among others, with tsunami warnings and monitoring of pollution in the oceans. In addition, the researchers have applications in the monitoring of fish and mammals in the sea life.
