The growing need for ocean observation systems has stimulated considerable interest within the research community in advancing the enabling technologies of underwater wireless communication and underwater sensor networks. Sensors and ad hoc sensor networks are the emerging tools for performing extensive data-gathering operations on land, and solutions in the subsea setting are being sought. Eff...

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 t...

This paper reviews the physical fundamentals and engineering implementations for efficient information exchange via wireless communication using physical waves as the carrier among nodes in an underwater sensor network. The physical waves under discussion include sound, radio, and light. We first present the fundamental physics of different waves; then we discuss and compare the pros and cons f...

Underwater wireless sensor networks (UWSNs) are the enabling technology for various underwater applications, and the interest in UWSNs is growing. Applications of underwater sensing range from oil industry to aquaculture, and include instrument monitoring, pollution control, climate recording, prediction of natural disturbances, search and survey missions. Location information is important for ...

Underwater acoustic sensor networks (UASNs) are often used for environmental and industrial sensing in undersea/ocean space, therefore, these networks are also named underwater wireless sensor networks (UWSNs). Underwater sensor networks are different from other sensor networks due to the acoustic channel used in their physical layer, thus we should discuss about the specific features of these ...

Wireless sensor networks (WSNs) consist of thousands of tiny, inexpensive and lowpower sensor nodes that perform collaborative tasks and organize themselves into multihop networks. These sensor nodes are deployed over a given area, including both the terrestrial and underwater environments. Consequently, WSNs can be divided into terrestrial wireless sensor networks (TWSNs) and underwater wirele...

Underwater Wireless Sensor Networks (UWSNs) can be used in ocean exploration and lake pollution monitoring. They use acoustic media to achieve sensor communications. UWSNs are essentially different from terrestrial RF-based sensor networks due to its highly variable, long propagation delay, and mobility nature. In this paper, we first describe our experimental design of low-cost underwater sens...

More than 70 percent of Earth is covered with water, while human knowledge of the underwater environment is negligible compared to the land. Underwater wireless acoustic sensor network (UWASN) is one of the newest technology to investigate the underwater. UWASNS is a subdivisions of WSNs in which a variable number of autonomous and self-organize sensor nodes and vehicles are deployed manually o...
