“…where , i m L and i v are the coverage search path of the UUV i on task m , and the search velocity of the UUV i , respectively. As shown in Figure 2a,b , i m L needs to be specially designed according to the UUV's search range and the task area's shape and size [4]. For the convenience of calculating the coverage search path, a maximum bounding rectangle is employed to approximate the irregular task areas.…”

“…To deal with large-scale geospatial search problems, Kuhlman et al use a novel iterative greedy method to plan the search paths of UUVs, which the algorithm scales well to the deployment of large groups of agents [3]. In [4], a new technology based on receiver operating characteristic (ROC) analysis is used to centrally handle the UUV task allocation problem, and the path planning problem is solved using a distributed model. To address the dynamic UUV task allocation problem, Sun et al design a tri-level optimization method to plan safe paths in severe ocean environments, in which UUVs have limited detection ranges and are required to respond to emergencies in real time [5].…”

In the dynamic task allocation of unmanned underwater vehicles (UUVs), the schemes of UUVs need to be quickly reallocated to respond to emergencies. The most common heuristic allocation method uses predesigned optimization rules to iteratively obtain a solution, which is time-consuming. To quickly assign tasks to heterogeneous UUVs, we propose a novel task allocation algorithm based on multi-agent reinforcement learning (MARL) and a period training method (PTM). The period training method (PTM) is used to optimize the parameters of MARL models in different training environments, improving the algorithm’s robustness. The simulation results show that the proposed methods can effectively allocate tasks to different UUVs within a few seconds and reallocate the schemes in real time to deal with emergencies.

“…Oceanic, biologic, and geologic variability of underwater environments impact in the search performance of teams of AUVs. To address search planning in these conditions, where the detection process is prone to false alarms, Baylog J. et al [135] applied a game theoretic approach to the optimization of a search channel characterization of the environment. The search space is partitioned into discrete cells in which objects of interest may be found.…”

Autonomous Underwater Vehicles: Localization, Navigation, and Communication for Collaborative Missions

Development of Autonomous Underwater Vehicles (AUVs) has permitted the automatization of many tasks originally achieved with manned vehicles in underwater environments. Teams of AUVs designed to work within a common mission are opening the possibilities for new and more complex applications. In underwater environments, communication, localization, and navigation of AUVs are considered challenges due to the impossibility of relying on radio communications and global positioning systems. For a long time, acoustic systems have been the main approach for solving these challenges. However, they present their own shortcomings, which are more relevant for AUV teams. As a result, researchers have explored different alternatives. To summarize and analyze these alternatives, a review of the literature is presented in this paper. Finally, a summary of collaborative AUV teams and missions is also included, with the aim of analyzing their applicability, advantages, and limitations.

New technologies are advancing and emerging day by day to improve the safety of humans by making use of various autonomous technologies. The continuous utilization of autonomous vehicles/systems in search and rescue (SAR) operations is a challenging research area particularly for marine-based activities. A comprehensive systematic literature review (SLR) providing an overview of improvisations that have been done in the field of autonomous technologies for search and rescue operation over the last five years has been compiled in this paper. A methodology for using autonomous vehicles in water for SAR operations has been incorporated and demonstrated. The focus of this study is to look at the various techniques and address different challenges faced for human beings’ safety during rescue operation. The comparison of results achieved for various technologies and algorithms is highlighted in this paper. This literature survey proves to be a good source of information for fellow researchers to precisely analyze the study results.
