<p>The present technology relates to advanced metering system mesh networks. Especially, the present invention relates methodology for an advanced metering system mesh network with multiple mode downlink routing, comprising: establishing a network including a central facility and a plurality of node devices, at least some of which node devices comprise metrology devices, and at least some of which node devices comprise cell masters which provide communications between the central facility and others of the node devices associated therewith in respective cells formed by each respective cell master; configuring the network for bi-directional communications between the central facility and each of the plurality of node devices; from each node device associated with a given specific cell master in a respective cell formed thereby, providing information to such given specific cell master about communications links of each of such node devices in such respective cell; selectively sending a monocast downlink message from a given respective cell master to a specific node device associated therewith, using a monocast downlink path determined by such given respective cell master based on its received information from all node devices associated therewith; and selectively sending a broadcast downlink message from a given respective cell master to all node devices associated therewith. The invention also relates to a respective metering system mesh network and a metrology device for use in such a mesh network.</p> |
