Abstract: A node within a wireless mesh network is configured to forward a high-priority message to adjacent nodes in the wireless mesh network by either (i) transmitting the message during successive timeslots to the largest subset of nodes capable of receiving transmissions during each timeslot, or (ii) transmitting the message on each different channel during the timeslot when the largest subset of nodes are capable of receiving transmissions on each of those channels.

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.

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 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 node within a wireless mesh network is configured to record a zero crossing of alternating current or alternating voltage drawn by a single-phase power consumer and a precise timestamp when the zero crossing occurred, thereby generating timestamped zero crossing data. The node receives similar zero crossing data from a neighboring node. The node then compares the timestamped zero crossing data with the received zero crossing data to determine whether the phase associated with the node is equivalent to, leads, or lags the phase associated with the neighboring node. The node then acquires a positive phase identification associated with the neighboring node. Based on the phase identification, and based on the phase difference between the two nodes, the node infers the phase associated with the single-phase power consumer. That phase indicates the specific power line within a three-phase power distribution network to which the single-phase power consumer is coupled.

Abstract: One embodiment of the present invention sets forth a technique for transmitting data in a frequency hopping spread spectrum (FHSS) wireless communication system. A multi-channel receiver is configured to receive data from one or more channels simultaneously. The multi-channel receiver enables efficient implementation of a transmission protocol in which multiple candidate nodes within a wireless mesh network are polled for availability to receive a packet of data. The packet of data is transmitted to one or more available nodes based on prevailing link conditions, thereby increasing the likelihood of successful delivery. Data flooding may be selectively implemented to further increase the likelihood of successful delivery.

Abstract: A node within a wireless endpoint device may be coupled to multiple heterogeneous networks simultaneously. The node is configured to select between the different networks based on various constraints associated with the endpoint device, applications executing on the endpoint device, traffic routed by the endpoint device, and constraints associated with the multiple networks. Based on these different constraints, and based on the current operating mode of the node, the node rates each network, and then selects the network with the highest rating to be used for routing purposes.
