In this paper we address the problem of how to implement directed dispatching of information in homogeneous excitable media. To do this, we surveyed cellular automaton models which reveal spatial oscillating patterns of excitation. Thus we discovered a medium where any element at rest was excited if just two of its nearest neighbours were excited. A medium of this kind, the 2+ medium, does not support the spreading of ordinary autowaves, but in its evolution one can find compact movable groups of excited states. Here we demonstrate that such solitary waves with particle-like behaviour will change their velocity vectors as a result of external singular stimulation. Thus they can be used as objects with controllable movement which transmit information in disordered surroundings. The results of this work can be utilised in the design of molecular computers.
