INTRODUCTION AND STATE-OF-THE-ART
Maritime tasks performed by manned vessels are often
expensive, and can only be performed at low-resolution, both
in time and space, when compared to Unmanned Maritime
Systems (UMS) [1]. UMS can execute variety of tasks, such
as sea-border patrolling, search and rescue missions, sea
demining, marine oil spill clean-up, environmental
monitoring, among others [2-4]. Swarms of inexpensive
aquatic drones have potential to perform these tasks at a
significantly reduced operational cost. Applications of swarms
of aquatic drones can be divided into two categories:
monitoring and mission-oriented (see Fig. 1).
