Abstract
This paper studies connectivity maintenance of robotic networks that
communicate at discrete times and move in continuous space. Given a
desired collective motion, we propose a distributed coordination
algorithm that allows the robots to select a motion as close as
possible to the original one while, at the same time, maintaining
connectivity. The algorithm works under imperfect information
caused by delays in communication and the robots' mobility. We
analyze the correctness of the algorithm by formulating it as a game
against a hypothetical adversary who chooses system states
consistent with observed information. The technical approach
combines tools from algebraic graph theory, linear algebra, wireless
communications, and systems and control.
