The Underwater Swarm is a particular Underwater Network configuration characterized by nodes very close one to each other, with mobility capability. The structure of the network is that of a distributed network, in which the nodes, through the exchange of control information, will take decisions in collaborative manner. This type of network raises challenges for its effective design and develop...

High cost and high power consumption of underwater acoustic modem have limited the applications and researches of underwater wireless sensor networks (UWSN). This paper presents a node architecture and its low-cost realization to deal with such problems as high cost, high power consumption, large volume, and relative localization in a dense UWSN. Some fundamental functions like short range unde...

Data collection in underwater wireless sensor networks (UWSNs) using autonomous vehicles (AUVs) is a more robust solution than traditional approaches, instead of transmitting data from each node to destination node. However, the design delay-aware and energy-efficient path planning for AUVs one most crucial problems collecting UWSNs. To reduce network delay increase lifetime, we proposed novel ...

The aim of the Smart and Networking Underwater Robots in Cooperation Meshes (SWARMs) project is to make autonomous underwater vehicles (AUVs), remote operated vehicles (ROVs) and unmanned surface vehicles (USVs) more accessible and useful. To achieve cooperation and communication between different AUVs, these must be able to exchange messages, so an efficient and reliable communication network ...

Underwater localization is a challenging task as its efficacy is affected by propagation delays, motion-induced doppler shift, phase and amplitude fluctuations, multipath interference etc that is inherent in underwater acoustic channels. In this paper, we consider a recently proposed Underwater Positioning Scheme, which offers unique localization only in a finite region. We quantify the conditi...

The use of an autonomous surface vehicle as an auxiliary agent to improve connectivity in a network of autonomous underwater vehicles is investigated. An algorithm is developed that consists of an optimal waypoint generator and a minimum-time guidance law that is used to steer the vehicle to the waypoint. This algorithm is used together with a communication architecture to improve underwater ve...

Models of biological regulatory and signalling networks are increasingly used to formally describe and understand complex biological processes. Such models are often repaired whenever new observations become available, because the model cannot generate behaviours consistent with the new observations, or because the behaviours are contradictory. This process of model repair is often manual and t...

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...
