Problem Definition
The Model
A mobile robotic sensor (or simply sensor) is modeled as a computational unit with sensorial capabilities: it can perceive the spatial environment within a fixed distance V > 0, called visibility range, it has its own local working memory, and it is capable of performing local computations [6, 7].
Each sensor is a point with its own local coordinate system, which might not be consistent with the ones of the other sensors. The sensor can move in any direction, but it may be stopped before reaching its destination, e.g., because of limits to its motion energy; however, it is assumed that the distance traveled in a move by a sensor is not infinitesimally small (unless it brings the sensor to its destination).
The sensors have no means of direct communication to other sensors. Thus, any communication occurs in a totally implicit manner, by observing the other...
