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 wireless node that bridges a wireless communications gap between a first wireless device, such as a smart meter, and a wireless network, such as a smart grid network, by repeating wireless communications received by the wireless node. The wireless node is integrated with another powered device common to buildings to provide a clandestine improvement to wireless communications. Additionally, the wireless node may effect testing of the powered device and provide results of the test wirelessly to remote devices. The wireless node may take the form of an exit sign, an emergency light, a speaker, and a combination of one or more of these devices. The wireless node may also track power consumption of the repeater portion of the wireless node to provide billing credit to power consumers.

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: Systems and methods for identifying and targeting power outages are provided. Electric meters of a system receive electric power from power distribution equipment in a power distribution network and information that identifies the respective power distribution equipment from which the meters receive electric power. Communication nodes are associated with electric meters and receive, from neighboring communication nodes, information identifying each respective neighboring communication node and the information identifying the power distribution equipment from which respective electric meters, associated with neighboring communication nodes, receive electric power. A communication node of a particular electric meter can select a suitable communication node of a neighboring electric meter with which it can communicate. When the particular electric meter experiences a loss in power, it can then transmit an immediate regarding the loss in power to the selected communication node.

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: Systems and methods for detecting device failures in a network having nodes coupled to a central controller, in which a first of the nodes communicates with the central controller via a second of the nodes. When the second node determines that the first node has not transmitted a predetermined number of messages over a predefined number of time periods, the second node provides a failure alert to the central controller. The central controller records a failure alert received from the second node in a log. Based on a set of failure alerts received from a number of nodes recorded in the log, the central controller determines whether the first node has failed.
