Maritime Networking: Bringing Internet to the Sea

Abstract

Maritime networks establish wireless multi-hop networks to provide wireless broadband service at sea, connecting various kinds of ships, maritime buoys, and beacons. The maritime networks possess two distinguishing characteristics highly affected by maneuver at sea-dynamic link quality and bandwidth constrained, and dynamic network topology-that warrant specific attention. Unlike land vehicles, maneuver at sea is affected by sea surface movement and wave occlusions, which can cause unstable environment with a high rate of link breakages caused by low link stability, as well as low and highly variable bandwidth. In spite of the need to achieve performance close to high-speed terrestrial wireless broadband service on land, there is only a perfunctory effort to investigate maritime networks. There is an urgent need to refresh the interest to investigate, as well as to further enhance, maritime networks. This paper presents a review of the limited research works of this topic, which revolve around the networking issues in the link, network, and upper layers, in the literature. The objective is to establish a foundation in order to motivate a new research interest in maritime networks. Open issues are also presented to foster new research initiatives in this burgeoning and exciting area. INDEX TERMS Maritime network, ship ad hoc network, wireless network.

Towards Smart Port Infrastructures: Enhancing Port Activities Using Information and Communications Technology

“…Smart ships use ICT, such as big data, sensing and detection devices, and IoT, to reduce environmental impact and enhance ship safety, operations, and maintenance in various aspects, such as energy efficiency management, communication network, and navigation. Examples of smart ships include Great Smart that provides intelligent ship operations, maintenance, and navigation [91], and Telenor Maritime's Smart Ship that provides smart communication network for digital lifestyle onboard a cruise [92], [93]. Examples of smart ship projects are the Ishin Next -MOL Smart Ship Project that aims to enable safe autonomous sailing and to reduce environmental impact [94], and the Hyundai Heavy Industries and Accenture project that aims to enable datadriven decision making for efficient operations [95].…”

Non-Satellite Broadband Maritime Communications for e-Navigation Services

“…Clear limitations of the currently employed maritime communication solutions and the availability of many broadband technologies successfully deployed on-shore have created much interest in their possible adaptation for the off-shore use [19], [20]. Several research initiatives such as [21]- [23] have been undertaken to find a way to utilize various Wireless Local Area Network (WLAN) and Wireless Metropolitan Area Network (WMAN) technologies in maritime conditions.…”

Dynamic Spectrum Allocation Access Using Cognitive Radio Networks in a Maritime

“…Attention in this area is needed in maritime network despite the fact that broadband access is very common on land. The difficulty in managing maritime network is the inability to maneuver at sea, constrained bandwidth and the dynamic network topology that warrant specific attention [1]. Unlike the land vehicles, maneuvering at sea is affected by sea surface movement and wave obstructions [2].…”
