Underwater sensor networks are emerging as a promising distributed data management system for various applications in underwater environments, despite their limited accessibility and restricted energy capacity. With the aid of recent developments in ubiquitous data computing, an increasing number of users are expected to overcome low accessibility by applying queries to underwater sensor networ...

Advances in low-power electronics design and wireless communication have enabled the development of low cost, low power micro-sensor nodes. These sensor nodes are capable of sensing, processing and forwarding which have many applications such as underwater networks. In underwater wireless sensor networks (UWSNs) applications, sensors which are placed in underwater environments and predicted ena...

Underwater sensor network consists of number of various sensors and autonomous underwater vehicles deployed underwater to coordinate, interact and share information among them to carry out sensing and monitoring functions. Underwater environment differs from terrestrial radio environment both in terms of energy costs and channel propagation phenomena. The goal of the project is to reduce the oc...

Over 70% of our planet is covered by water. It is widely believed that the underwater world holds ideas and resources that will fuel much of the next generation of science and business. Unfortunately, underwater operations are fraught with di culty due to the absence of an easy way to collect and monitor data. In this thesis we propose a novel underwater sensor network designed to mitigate the ...

Deployment of sensors in the underwater acoustic sensor network is a very challenging task due to the complex 3d environment in underwater sensor networks because acoustic signal is affected by salinity, temperature, and pressure. The main objective of deployment algorithm is to achieve maximum coverage with a minimum number of underwater acoustic sensor nodes or surface gateways in underwater ...

Underwater acoustic network is one of the rapidly growing areas of research and finds different applications for monitoring and collecting various data for environmental studies. The communication among dynamic nodes and high error probability in an acoustic medium forced to maximize energy consumption in Underwater Sensor Networks (USN) than in traditional sensor networks. Developing energy-ef...

Recently, data collection from seabed by means of underwater wireless sensor networks (UWSN) has attracted considerable attention. Autonomous underwater vehicles (AUVs) are increasingly used as UWSNs in underwater missions. Events and environmental parameters in underwater regions have a stochastic nature. The target area must be covered by sensors to observe and report events. A ‘topology cont...

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...

Underwater Sensor Networks (UWSN) are gaining increasing importance. The main constituents of UWSN are Static Acoustic sensor nodes and Autonomous Underwater Vehicles. The sensor nodes located in a particular depth are to pass the data to the sinks. As acoustic transmission range is limited, the information has to be routed via many hops. We are proposing a distance based routing scheme for suc...
