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 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. In a medium latency communication mode, a given BPD receives data during a receive window that is scheduled to occur within either the first half of a communication window or the second half of the communication window, depending on the parity of the hop layer where the BPD resides. With this approach, a data packet can traverse one hop of the BPD mesh per communication window. In a low-latency communication mode, a given BPD receives and transmits data according to an alternating pattern that depends on the parity of the hop layer where the node resides. With this technique, a data packet can traverse multiple hops of the BPD mesh within a single communication window. These techniques also are applicable to CPDs and other types of nodes as well.

Abstract: A method for directing a vehicle to a parking space within an environment is disclosed. The method includes selecting a parking space from a collection of parking spaces within the environment, further selecting one or more lighting devices within the environment based at least on a location of the selected parking space, and sending a signal to the one or more lighting devices to generate a lighting pattern visible to a driver of the vehicle, where the lighting pattern directs the driver to navigate the vehicle toward the parking space. In addition, the vehicle may be navigated using radio navigation algorithms based on beacon signals broadcasted from streetside devices, such as lighting devices or parking meters.

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: A method for removing credentials from a smart grid device includes: receiving, by a receiving device, a removal request, wherein the removal request includes a device identifier associated with a smart grid device and is signed by an entity associated with a set of security credentials stored in a memory of the smart grid device, the set of security credentials restricting access to one or more components or operations of the smart grid device; extracting, by a processing device, the device identifier included in the received removal request; generating, by the processing device, a permit configured to remove the set of credentials from the smart grid device, wherein the generated permit includes the extracted device identifier; and transmitting, by a transmitting device, the generated permit to the smart grid device for removal of the set of credentials from the memory of the smart grid device.

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: One embodiment of the present disclosure sets forth a technique for convergence and automatic disabling of access points in a wireless mesh network. Specifically, an access point within a wireless mesh network computes one or more network metrics to determine whether the metrics are unfavorable or favorable. If the network metrics are favorable, then the access point disables the access point's network connection. An access point turns the network connection back on based on whether a routing was lost for at least a preset amount of time, utilization of one or more neighboring access points is above a preset value, or one or more network metrics have degraded by a certain percentage value. One advantage of this approach is that cost savings may be achieved when the number of access points dynamically changes to accommodate varying communications conditions.

Abstract: A wireless communication network system includes a plurality of nodes. Each node from the plurality of nodes includes a plurality of communication modules. Each module includes a modem and is configured to operate according to a communication protocol. Each communication module is configured to monitor its own communication parameter data and to cooperate with companion modules of a node by sharing communication parameter data, for instance through a coordination unit. Each communication module is further configured to allow, preferably according to a predefined set of rules, communication using a protocol of one communication module by utilizing a band associated with a companion module. The sharing of communication parameter data between modules may be continuous sharing or periodic sharing.

Abstract: A source node residing within a wireless mesh network is configured to transmit data packets to downstream nodes also residing within the wireless mesh network. Upon receipt of a data packet, a given downstream node determines a channel on which to transmit an acknowledgement packet and a sub-interval of time during which to transmit the acknowledgement packet based on a short ID assigned by the source node. At the determined sub-interval of time, the downstream node transmits the acknowledgement packet to the source node on the determined channel.
