Systems and methods for routing packets using node virtual locations are disclosed. Such a virtual location may be determined, for example, by determining a geographic location that is central to other nodes with which the node can communicate. In certain embodiments, a node's virtual location may more accurately represent an approximate center point of a node's communication range. In one exemplary embodiment, a node's virtual location is an average of the geographic locations of radio nodes with which the node is in communication.

Systems and methods for network routing using virtual network node locations

Systems and methods for over-the-air firmware distribution to battery-powered devices are disclosed. Such over-the-air distribution is accomplished, for example, using a non-battery-powered device as a buffer, for example, to reduce or eliminate the delay time of the over-the-air network. The firmware can be sent to and stored on a nearby, non-battery-powered device and then sent from there to the battery-powered endpoint device. The distribution of firmware to battery-powered devices may be implemented in an Advanced Metering Infrastructure (AMI) system, a mesh network, a multi-channel radio network, or any other environment in which firmware distribution is desirable.

Methods and systems for distributing firmware through an over-the-air network

Methods and systems for providing accurate time-keeping on battery-powered communication devices used in AMI systems, mesh networks, and multi-channel radio networks. One embodiment allows the use of low power (and low cost) crystals in battery-powered endpoints by periodically correcting the poor timing of these crystals using communications with a nearby, non-battery-powered device. Such communications allow the battery-powered devices to align their timing with that of their non-battery neighbors, among other things.

A list of nodes is segmented into one or more segments, each segment having a node limit and a segment criteria, attributes associated with a first node are identified, a determination is made whether to add the first node to a particular segment of the node list based on the node limit and the attributes of the first node, nodes are ranked nodes in the particular segment, and a determination is made whether to remove a candidate node from the particular segment based on the node limit.

Selective node tracking

Systems, methods, and devices for consolidating network packetized data are disclosed. Data packets are received by a consolidator. Common content and unique attributes of the packets are identified. A consolidated packet is created and the consolidated packet is transmitted in response to a condition.
