Abstract: A node within a wireless mesh network is configured to select a primary path through an access point and to designate that access point as the primary access point for the node. The access point then transmits a failover message indicating that the node designated that access point as the primary access point for the node at a particular time. When another access point receives the failover message, the other access point may determine that the first node has also designated the other access point as the primary access point for the node, and may then de-register the node and stop advertising a primary path to the node.

Abstract: One example embodiment provides a method and system where a node in a utility network registers with one or more access point devices associated with one or more local area utility networks. The utility node generates a unique network address using a network address prefix of a network address associated with the access point device. The utility node registers with a DNS server. Messages sent to the utility node are routed through the access point corresponding to the received prefix used to generate the unique network address for the utility node. The network address for the utility node and access point may be IPv6 addresses and the network address prefix may be an IPv6 prefix, or may be an IPv4 address.

Abstract: A first subregion of a wireless mesh network is configured to transmit a data packet across multiple communication links to a second subregion of the wireless mesh network. Due to varying connectivity levels associated with the multiple communication links, the second subregion receives different versions of the data packet. A designated node within the second subregion receives the different versions and then combines those versions to reconstruct the data packet. The designated node may receive the multiple versions of the data packet from nodes within the first subregion and/or receive multiple versions of the data packet from nodes residing within the second subregion. In this fashion, the designated node leverages path diversity between the first and second subregions to remedy poor connectivity between those subregions.

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 technique for providing an improved way to update the nodes of a wireless mesh network is described. An upgrade engine executing on a server connected to the wireless mesh network determines a topology of the network, subdivides the network into a plurality of clusters based on the topology of the network, and seeds a small number of nodes within each cluster. The upgrade engine manages the upgrade process, notifying particular nodes within each cluster when to search for an upgrade package (e.g., an image of a new firmware) stored in an adjacent node. The upgrade engine also monitors success and failure of each node and delivers the upgrade package to a node directly when the node fails to download the upgrade package from an adjacent node within the network.

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, including voltage fluctuations, current levels, temperature data, humidity measurements, and other observable physical quantities. The nodes execute stream functions to process the recorded time series data and generate data streams. The node is configured to transmit generated data streams to neighboring nodes. A neighboring node may execute other stream functions to process the received data stream(s), thereby generating additional data streams. A server coupled to the wireless mesh network collects and processes the data streams to identify events occurring within the network.

Abstract: A battery-powered node within a wireless mesh network performs energy-aware packet routing based on multiple factors. The battery powered node computes, for a given link to an adjacent node, the energy needed to transmit a packet to the adjacent node. The battery-powered node also determines the amount of battery energy remaining in the adjacent node. Based on these two factors, the battery powered node computes a link cost associated with the link to the adjacent node. The battery-powered node performs a similar computation for all adjacent nodes and then forwards packets via these adjacent nodes based on the associated link costs. The battery-powered node also maintains a table of routes through adjacent nodes, and reroutes packets through different adjacent nodes in response to link failures.
