    摘要: Methods and systems of managing node migration in a wireless network where nodes may spontaneously migrate from a first communication path to a second communication path. The system includes a first collector disposed within the first communication path and a second collector disposed within the second communication path, a network management server that determines a network state and maintains a database of the network state. When the network management server detects that a node has migrated from the first communication path to the second communication path, information associated with the node is retrieved from the first collector and downloaded to the second collector to ensure the proper operation of the node in the network.

    摘要: An automated meter reading system is provided. The system includes a host server interfaced to a plurality of nodes where each node communicates with a number of utility meters. The system selects a group of noninterfering nodes and uses an RF broadcast from the host server to initiate the reading of meters and the uploading of meter data provided by those meters to the nodes and, ultimately, to the host server. The system also has a number of gateways that communicate with a plurality of nodes, grouped to form sets of noninterfering gateways. In this embodiment, the system selects a set of noninterfering gateways and uses an RF broadcast from the host server to initiate the reading of meters and the uploading of meter data provided by those meters to the nodes and, ultimately, through the gateways to the host server. A method for using an outbound RF channel to automatically read meters is also provided.
