Underwater acoustic networks in a rapidly growing area of research as it finds different applications for monitoring and collecting data for environmental studies and military surveillance. The need for creating a new set of protocols optimized acoustic communication arises from the major differences in the underwater acoustic communication and terrestrial radio communication. Energy efficiency...

High cost of development and deployment coupled with the complexity of the underwater acoustic channel makes it important to develop simulation tools which can assist in investigating underwater sensor networks and mobile autonomous underwater vehicular communications. Some recent developments have led to simulators which provide the ability to simulate mobile and stationary underwater acoustic...

The underwater acoustic channel has many fundamentally different properties to the conventional radio-based wireless channel. Communication is changed drastically by acoustic propagation speeds that are five orders of magnitude slower than radio. This, coupled with bandwidth limitations, high transmit energy cost, complex multi-path effects, and high bit-error rates make the issue of medium acc...

The properties of underwater acoustic channel are quite different from those of terrestrial wireless sensor networks. There are many challenges to design an efficient media access control (MAC) protocol for underwater acoustic sensor networks (UWASNs). In order to overcome the long propagation delay and low available bandwidth of UWASNs, an enhanced dynamic token protocol (EDTP), is proposed in...

In this paper approach for the underwater sensor network based on the blue-green laser has been proposed. We describe the application of the underwater sensor network in the undersea exploration, and discuss the difficulties in the traditional underwater sensor network. A basic of prototype of underwater laser sensor network has been advanced, which include the architecture of laser network and...

Three-dimensional Under-Water Acoustic Sensor Networks (UWASN) are supposed to be deployed for many applications. However, a protocol for sensors’ self-localization and time-synchronization in UWASN remains a challenge problem. In this paper, we developed a multilateration algorithm which could reliably localize and synchronize underwater sensor networks by acoustic ranging. To our best knowled...
