High Speed Maritime Mesh Networks Programme

The Programme
The High Speed Maritime Mesh Networks Programme has the mission of exploring and using new scientific and engineering techniques for the development of new high speed maritime networks for port-areas, above-sea and under-sea to support communications with improved bandwidth, reliability and pervasiveness.

Our vision is to develop these new generation communication networks to enable the development of new maritime applications and services that are not possible today due to the current state of the art technologies.  

In the next three years, the programme will focus on several key areas.  The first area is related the development of practical distributed feedback (DFB) fiber laser array for all optical underwater sensing, which can be used in applications such as port security, waterfront security and seismic monitoring in the oil and gas industry.  The focus of this work will be on the design of the fiber laser, grating methods and signal processing algorithms for a robust system that will be able to withstand high temperature and long distance operations.   

The second area is related to the development of a high speed ship-to-ship/shore mesh network that is targeted for use in narrow water channels and traffic lanes that are close to the shoreline.  The system will be built to complement existing Satellite communications and the focus of the technology development is the design of the robust networking schemes for the ship-to-ship/shore mesh networks and the middleware to glue to the Satellite system. 

The third area is related to providing more robust communications for a school of submersibles, which are targeted for applications related to geophysical survey in the Oil and Gas industry.  The focus of the technology development will be on providing robust networking and localization protocols for use in accurate coordination and control of the distributed submersibles.

The fourth area is related to providing alternative communications based on electrical conduction for underwater data transmission but at a much higher speed than current acoustic communications.  The application area is also targeted towards applications related to geophysical surveys in the Oil and Gas industry.
