Abstract:
Various aspects of the present invention relate to optimizing the distribution of point-to-point and broadcast messages in a layered mesh network of nodes. In one aspect, a node in the mesh network identifies a point-to-point frequency for sending a point-to-point message to a preferred node, which facilitates communication with a collector node. The node also identifies a broadcast frequency of the preferred node that is distinct from the point-to-point frequency. According to one configuration, the broadcast frequency is offset a predetermined number of frequency channels from the point-to-point frequency. In addition to listening on the broadcast frequency, the node further identifies and listens on a receive frequency for point-to-point messages from other nodes.
