摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： One embodiment of the present invention sets forth a wireless communications system configured to efficiently operate within an arbitrarily and uniquely defined set of channels. Each one of the set of channels has an assigned digital radio transceiver instance configured to operate according to transmission requirements that are unique to the corresponding channel. A set of digital radio transceiver instances comprises a meta-transceiver, which enables communications to one or more other devices via one or more digital radio transceiver instances.

摘要： Devices and methods for securely upgrading devices, such as field upgradeable units, are disclosed. In response to receiving an update object, a device may determine whether a predefined location of memory includes a predetermined value. Based on the value in the predefined location, the device may store the received update object in a verification portion of the memory. After verifying the authenticity of the update object, the device may copy the update object from the verification portion of the memory to an inactive portion. The inactive portion of the memory can be swapped with an active portion of the memory, such that the inactive portion becomes active.

摘要： 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.

摘要： 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.
