This paper provides an overview of the Naval Postgraduate School ARIES autonomous underwater vehicle and its control and navigation performance. An attempt is made to highlight its current operational capabilities and provide a description of future enhancements for greater mission utility and flexibility. An overview of the vehicle design along with descriptions of all major hardware component...

Underwater Wireless Sensor Network (UWSN) is a particular kind of sensor networks which is characterized by using acoustic channels for communication. UWSN is challenged by great issues specially the energy supply of sensor node which can be wasted rapidly by several factors. The most proposed routing protocols for terrestrial sensor networks are not adequate for UWSN, thus new design of routin...

Interference-aware routing protocol design for underwater wireless sensor networks (UWSNs) is one of the key strategies in reducing packet loss in the highly hostile underwater environment. The reduced interference causes efficient utilization of the limited battery power of the sensor nodes that, in consequence, prolongs the entire network lifetime. In this paper, we propose an energy-efficien...

In recent years, wireless communication technologies have been increasingly deployed in challenging environments where there is no communication infrastructure, as evidenced by the many efforts in building and deploying wireless sensor networks for wildlife tracking [22, 43], underwater sensor networks [38, 41], disaster relief team networks, networks for remote areas or for rural areas in deve...

In Underwater Wireless Sensor Network, for mobile target localization schemes, there exists long propagation delay of sensor nodes' messages. Further, the flexibility node schemes to adapt in harsh underwater environment is major issue. As one principal aspects that disturb time harmonisation nodes communication. It must be adjusted attain precise and accurate localization. this article, we pro...

Abstract We study the problem of modeling temporal networks constrained by size a concurrent set, characteristic shown to be important in many application areas, e.g., transportation, social, process, and other networks. propose competition-driven model for generation such Our method carries out turns competitions along timeline where each node network is labeled with probability gain outgoing ...

ad hoc networks are multi-hop wireless networks without a pre-installed infrastructure. such networks are widely used in military applications and in emergency situations as they permit the establishment of a communication network at very short notice with a very low cost. video is very sensitive for packet loss and wireless ad-hoc networks are error prone due to node mobility and weak links. h...

In the past few years wireless Sensor Network has been an emerging technology. As it is a permutation of computation, sensing, and communication. In the 70% of the earth, a huge amount of unexploited resources lies covered by oceans. To coordinate interact and share information among themselves to carry out sensing and monitoring function underwater sensor network consists a number of various s...

Underwater communication systems have drawn the attention of the research community in the last 15 years. This growing interest can largely be attributed to new civil and military applications enabled by large-scale networks of underwater devices (e.g., underwater static sensors, unmanned autonomous vehicles (AUVs), and autonomous robots), which can retrieve information from the aquatic and mar...
