    Abstract: A node residing within a wireless mesh network is configured to transmit a state transition message to a downstream node also residing within the wireless mesh network. The state transition message indicates a new operating state for the downstream node. Upon receipt of the state transition message, the downstream node may transition to the new operating state and then transmit an acknowledgement message back to the node that sent the state transition message. Alternatively, the downstream node may transmit the acknowledgement message back to the node that sent the state transition message first, and then transition to the new operating state.

    Abstract: A wireless mesh network includes heterogeneous types of nodes, including continuously-powered nodes and battery-powered nodes. The battery-powered nodes may reside in a sleeping state most of the time to conserve power. The various nodes in the network may communicate with one another by transmitting and receiving at scheduled times and on scheduled frequencies. The battery-powered nodes may become active during the scheduled transmit and receive times. Network management nodes may facilitate network formation by transmitting information that reflects the scheduled transmit and receive times across the network. Based on this data, the continuously-powered nodes and battery-powered nodes may establish communication links with one another.

    Abstract: A method for enabling a scalable public-key infrastructure (PKI) comprises invoking a process of receiving a message for a device, identifying an association ID for the device, retrieving encrypted association keys stored on the server for communicating with the device, the encrypted association keys encrypted using a wrapping key stored on a Hardware Security Module (HSM). The method further comprises sending the message and the encrypted association keys to the HSM, unwrapping, by the HSM, the encrypted association keys to create unwrapped association keys, cryptographically processing the message to generate a processed message, deleting the unwrapped association keys, sending the processed message to the device, and invoking, concurrently and by a second application, the process.

    Abstract: A node in network is configured to buffer data received from other nodes across multiple channels. The node process a portion of the buffered data associated with a subset of those channels. When the node receives data on that subset of channels that includes a notification, the node then processes a larger portion of the buffered data associated with a larger number of channels. In doing so, the node may identify additional notifications include within data that was buffered but not previously processed. The node may also coordinate with other nodes in order to process buffered data upon identification of a notification.

    Abstract: A wireless mesh network includes a mesh of continuously-powered devices (CPDs) and a mesh of battery-powered devices (BPDs). The BPDs are organized into hop layers based on hopping distance to the mesh of CPDs. The CPDs transmit time beacons to BPDs in a first hop layer during a first receive window associated with the first hop layer. The BPDs in the first hop layer then transmit time beacons to BPDs in a second hop layer during a second receive window. In this manner, the wireless mesh network propagates time values throughout the BPD mesh. Based on these time values, the BPDs power on during short time intervals to exchange data with neighboring BPDs, and then power off for longer time intervals, thereby conserving battery power. The techniques described herein for conserving battery power for BPDs may also be applied to conserve power consumption of CPDs.

    Abstract: A communication device detects whether anomalous events occur with respect to at least one node in a utility network. The communication device has recorded therein threshold operating information and situational operating information. The threshold operating information includes data indicative of configured acceptable operating parameters of nodes in the network based on respective locational information of the nodes. The situational information includes data indicative of configured operation data expected to be received from nodes in the network during a predetermined time period, based on a condition and/or event occurring during the time period. The communication device receives operation data from nodes in the network, and determines whether the operation data from a node constitutes an anomalous event based on a comparison of the received operation data with (i) the threshold operating information defined for the node and (ii) the situational information. The communication device outputs notification of any determined anomalous event.

    Abstract: Nodes within a wireless mesh network are configured to monitor time series data associated with a utility network (or any other device network). One or more servers coupled to the wireless mesh network configures a data ingestion cloud to receive and process the time series data from the nodes to generate data streams. The server(s) also configure a distributed processing cloud to perform historical analysis on data streams, and a real-time processing cloud to perform real-time analysis on data streams. The distributed processing cloud and the real-time processing cloud may interoperate with one another in response to processing the data streams. Specifically, the real-time processing cloud may trigger a historical analysis on the distributed processing cloud, and the distributed processing cloud may trigger real-time processing on the real-time processing cloud. Any of the processing clouds may encompass edge nodes configured to perform real-time processing and generate data streams.
