Abstract:
1. A method for optimizing an advanced metering system mesh network, comprising: establishing a network including a central facility root node and a plurality of linked node devices, at least some of the node devices comprising metrology devices; configuring the network for bi-directional communications between the central facility root node and each of the plurality of node devices; computing an average local propagation delay for each node device for each one-hop link to itself; computing a total value of propagation delay along each path from each node device to the central facility root node based on the average local propagation delay and global propagation delay values stored in immediate neighbor devices; selecting at each node device the lowest value of total values of propagation delay to define its own global propagation delay value; and conducting communications using the path corresponding to the selected value, whereby communications among nodes within the network are optimized.
