TL;DR: A distributed protocol for communication among autonomous underwater vehicles is presented and issues relating to time delay, number of hops, power consumption, message collision and other practical issues are discussed and solved.
Abstract: This paper presents a distributed protocol for communication among autonomous underwater vehicles. It is a complementary approach for coordination between the autonomous underwater vehicles. This paper mainly describes different methods for underwater communication. One of the methods is brute force approach in which messages are broadcasted to all the communication nodes, which in turn will broadcast the acknowledgement. Issues relating to this brute force approach are time delay, number of hops, power consumption, message collision and other practical issues. These issues are discussed and solved by proposing a new method to improve efficiency of this proposed approach and its effectiveness in communication among autonomous underwater vehicles.

TL;DR: In this article, a maneuvering and control system simulator has been assembled using nearly the same control boards, LAN, scenarios and control programs as for an actual AUV system, and failure procedures such as emergency surfacing and obstacle avoidance, as well as standard cruising modes including straight constant speed running, course keeping, turning, diving, position keeping, crabbing, stopping and passing designated points can be verified through repeated computer runs of this AUV simulator.
Abstract: AUVs (autonomous underwater vehicles), which are maneuvered according to designated operation scenarios using nontethered systems, feature wide-ranging observation capability due to the un-connection of power and/or signal cables. Maneuvering scenarios and control software should be carefully formulated and checked so as to avoid unexpected AUV motion. Accordingly, a maneuvering and control system simulator has been assembled using nearly the same control boards, LAN, scenarios and control programs as for an actual AUV system. Scenarios and failure procedures such as emergency surfacing and obstacle avoidance, as well as standard cruising modes including straight constant speed running, course keeping, turning, diving, position keeping, crabbing, short turning, stopping and passing designated points can be verified through repeated computer runs of this AUV simulator.

TL;DR: In this paper, the authors built a ROV and equipped it with a surveillance system, which can be used in military, scientific research, film making under the water and monitoring underwater industrial structures and underwater network devices.
Abstract: Remotely operated underwater vehicles or ROVs are underwater robots that are used in science, entertainment, military and offshore oil industries. Their main function is to interact with the environment under the water in various ways. It is a very complicated system and uncommon in the developing or the underdeveloped countries around the world. Countries consisting many water bodies and prone to maritime incidents ROVs can be very useful in rescue missions. In this research work we built a ROV and equipped it with a surveillance system. Our ROV will be quite useful beside rescuers by monitoring the underwater and sending the video. It can also be used in military, scientific research, film making under the water and monitoring underwater industrial structures and underwater network devices.

TL;DR: In this paper, the authors proposed an operation of multiple AUVs using an ASV (Autonomous Surface Vehicle) to improve survey efficiency, which can relay information between an AUV and operators on a ship or on land.
Abstract: JAMSTEC has developed and operated several AUVs (Autonomous Underwater Vehicle) as platform for scientific investigation and explorations of seabed mineral resources [1–4]. Conventionally, a support vessel monitors only one AUV during its whole dive for safety and positioning. We propose an operation of multiple AUVs using an ASV (Autonomous Surface Vehicle) to improve survey efficiency. For this purpose, JAMSTEC has been developing an ASV “MAINAMI” with a length of 6 meters since 2013. It has a diesel engine, two thrusters and a rudder. The vehicle is equipped with an acoustic communication device and a satellite one, in order to relay information between an AUV and operators on a ship or on land.

TL;DR: The C2 system described above is being used in the STARFISH AUVs and has been used to perform single AUV surveying missions as well as multi-AUV cooperative positioning missions.
Abstract: Inspired by the command structure of a manned submarine, we have developed a Command and Control (C2) system for autonomous underwater vehicles (AUVs) that allocates mission, navigation and vehicle tasks to individual self-contained agents, each with their own responsibilities and behaviors. These agents are distributed over different levels of control hierarchies where they behave deliberately at the supervisory level and reactively at the vehicle and navigational level. The collective interactions among the pool of agents enables the AUV to achieve its mission objectives autonomously.
