A method, an apparatus, and a computer program product for facilitating local signaling among a plurality of agents are presented. An agent 100 including a digital processor 102 a transmitter 104, and a directional receiver 106 comprising a plurality of angular regions 108 is configured to enable the selection of a signal from a plurality of signals received on the basis of local data such as the strength of the received signal. The local data may be incorporated into a cumulative data portion of a signal that is passed from local agent 100 to local agent 100 across a plurality of agents 100 in order to provide a gradient across the plurality of agents 100. The gradient could be used, for example, to determine a shortest path across the agents. The signaling techniques described can also be used to determine the distance and direction to objects in the signaling path.
