In maritime networks, the communication links are characterized by high dynamics due to ship mobility and fluctuation of the sea surface. Some researchers have considered using Delay Tolerant Network (DTN) to improve the performance of data transmission in maritime environment. Most existing work on maritime DTNs usually uses simulation to evaluate the transmission performance in maritime DTNs. In...
This article presents the TRI-media Telematic Oceanographic Network (TRITON) project, which aims to develop a high-speed and low-cost maritime communication system. The article includes information pertaining to background studies, high-level architecture, network feasibility, maritime communication environment, technology developments, prototype implementations and link performance measurements....
Today, it is still hard to form an alternative network in a maritime environment besides using costly satellite links because of the lack of wireless infrastructure at sea. In the TRITON project, we are exploring the use of WiMAX-based mesh technology for over the horizon ship-to-ship communications with Delay Tolerant Network (DTN) features to provide less expensive wireless communication services...
We provide an overview of a Maritime Intelligent Transport System (ITS) which enables increased use of business and social ship based applications by new communications means. The system is based on a high speed maritime mesh network and is fully integrated with legacy satellite communications using our middleware system component. The Intelligent middleware enables user preferences driven use of...
We envisage extending the coverage of existing terrestrial wireless broadband wireless networks to the sea so that cost-efficient wireless access is available to the ships near the shore. The coverage extension is achieved through a multi-hop WiMAX wireless mesh networks where ships, maritime beacons and buoys are the nodes. In such a multi-hop network, routing protocol plays an important role in...
We envisage extending radio coverage of the existing terrestrial wireless broadband networks to the sea to provide ships with cost-efficient high-speed connection to the Internet. This is achieved by forming a WiMAX based maritime wireless mesh network where ships are network nodes connected to the land station across multiple hops. In such a maritime wireless mesh network, time slot allocation is...

WiMAX Mesh networking is of many advantages for intelligent transportation systems (ITS) applications. In long-hop-distance ITS networks, multi-channel transmission may alleviate problem of insufficiency of bandwidth when a network uses single frequency channel. This paper presents algorithm of multi-channel bandwidth allocation in WiMAX mesh networks. Simulation is carried out with a maritime simulator,...
This paper details a novel approach of developing a low-cost and high speed maritime ship-to-ship/shore mesh network to complement or replace satellite communications in narrow water channels or traffic lanes close to shorelines. To design the system, we gathered requirements from typical users of the system. We then carried out preliminary studies such as radio channel propagation over sea water,...
