摘要： One embodiment of the present invention sets forth a technique for performing time synchronization within a network. The technique includes receiving, from a first node in the network and at a first receive time, a first periodic beacon that includes a first network time associated with the first node. The technique also includes determining a second receive time at which a second periodic beacon from the first node is to be received based on the first network time and the first receive time. The technique further includes calculating a first listening window for the second periodic beacon based on the second receive time, a first jitter uncertainty, and a first drift uncertainty, and listening for the second periodic beacon during the first listening window.

摘要： DISAGGREGATION OF GAS LOAD TO DETERMINE METER OR SERVICE UNDER-SIZING Techniques determine if a gas service (e.g., piping and/or meter) is under sized for the customer's needs. In one example, flowrate information corresponding to gas usage at a service site over a first period of time is obtained. The flowrate information is disaggregated to determine an expected flowrate associated with each of two or more appliances having generally fixed-rates of gas consumption. Flowrate information is again obtained, corresponding to a second period of time. The second flowrate information is compared to one or more combinations (i.e., summations) of the expected flowrates associated with each of the two or more appliances. Based on the comparison, it may be determined that the service site is not appropriately sized. In an example, failure to detect two fixed-rate of gas-consumption appliances operating at their respective fixed-rates at the same time may indicate that the service cannot provide gas at a sufficient flowrate.

摘要： One embodiment of the present invention sets forth a technique for operating an electronic device within a cellular environment. The technique includes determining a coverage enhancement (CE) parameter and one or more radio frequency (RF) link parameters associated with a link between the electronic device and a cellular base station at a first point in time. The technique also includes computing a first estimate for a signal condition associated with the link based on the CE parameter and the one or more RF link parameters. The technique further includes determining that the signal condition is not adequate based on the first estimate and delaying transmission of one or more messages from the electronic device over the link until a second point in time that is later than the first point in time.

摘要： A wireless network includes nodes configured to implement an improved parent and path selection process to efficiently and reliably manage energy consumption of a battery powered device node. When a given node selects a path, the node transmits requests to multiple potential parent nodes. Each potential parent node transmits a metric that is indicative of the remaining battery life of the nodes in the path that includes the respective potential parent node. The given node then selects a parent node, and corresponding path, based on the metrics. More specifically, the given node selects a path, where at least one node on the selected path is less likely to prematurely exhaust the remaining battery life of the node, relative to the nodes in the other potential paths. As a result, the given node selects a path that optimizes battery consumption of the various battery powered nodes in the wireless network.

摘要： Methods and apparatus are disclosed to determine the location of endpoints of interest. An example method involves in response to detecting a transmission from the endpoint, determining whether the endpoint is an endpoint of interest. If the endpoint is the endpoint of interest, the example method involves sending a first command to the endpoint to increase a transmission rate of the endpoint, determining an estimated location of the endpoint using signal strengths of subsequent transmissions from the endpoint, and enabling the transmission rate of the endpoint to decrease.

摘要： A method of gas detection includes receiving, by a data collection device, reports of detected concentrations of a particular gas from one or more gas sensing devices having one or more associated gas sensors, receiving an alarm from a gas sensing device indicating a detected concentration greater than a predetermined threshold, and receiving concentration updates from the alarming device at a rate faster than that provided by its predetermined reporting schedule. The method may further include sending a command to one or more gas sensing devices nearby the alarming device to send concentration updates. The method may further include determining a location of a gas leak by triangulating the received updates from the alarming device and the nearby devices based on their locations and/or creating and displaying a gas concentration map based on the received updates from the alarming device and the nearby devices and their locations.

摘要： A network node device and method of determining a communication route to one or more other network nodes through a network. The method includes sending current routing information to a network management server (NMS), and receiving new or supplemental routing information from the NMS, this supplemental routing information determined by the NMS based on the current routing information of the network node and of the one or more other network nodes. The supplemental routing information may include lateral route information identifying designated routing nodes that form lateral band(s) of nodes that span the network, each lateral band including gate node(s) as entrances/exits to the lateral band. The method may further include determining, based on the supplemental routing information, a route to one or more of the other network nodes. A lateral band may facilitate a route through a chokepoint or other abnormal topological layout.

摘要： Disclosed are techniques to conserve battery of an endpoint device. Example techniques include adjusting the size of messages transmitted by an endpoint device and/or adjusting the transmission rate of an endpoint device. In some configurations, the one or more criteria are used by an endpoint device to determine what data fields to include within a message and/or adjust a transmission rate associated with the transmission of messages by the endpoint device. For instance, the one or more criteria may include the battery level of the device, the time of year, whether the data has already been transmitted by the endpoint device, whether the data has been acknowledged as received by another device, whether the endpoint device has been instructed by another device to reduce the message size and/or adjust the transmission rate, and the like.

摘要： ABSTRACT A device and method for locally authenticating an accessor device to access an operable device. The method comprises receiving reservation information at a validation device from an access granting device, the reservation information identifying one or more accessor devices as having permission to utilize the operable device, where the operable device is local to (e.g., within a predetermined proximity) of the validation device. The method further comprises receiving a request from an accessor device requesting permission to utilize the operable device, the request including an identifier of the requesting accessor device, validating the request based on the reservation information and the identifier, and when validation is successful, granting to the requesting accessor device permission to utilize the operable device. The method may further include receiving an instruction from the access granting device to revoke such permission from the requesting accessor device, and revoking such permission from the requesting accessor device.
