Abstract: In one embodiment, a method includes receiving training data, the training data including training video data representing video of a location in a quiescent state, training a neural network using the training data to obtain a plurality of metrics, receiving current data, the current data including current video data representing video of the location at a current time period, generating a reconstruction error based on the plurality of metrics and the current video data in the embedded space, and generating, in response to determining that the reconstruction error is greater than a threshold, a notification indicative of the location being in a non-quiescent state.

Abstract: In one embodiment, a device in a wireless network receives a request from a node in the network requesting electrical power. The device determines one or more power transmission parameters for the node. The device determines a power transmission schedule for the node. The device sends wireless network communications to the node in response to the request and based on the determined one or more power transmission parameters and transmission schedule for the node. The node converts the wireless network communications into stored electrical power.

Abstract: In one embodiment, a method comprises: receiving, by a network device in a data network, a wireless data packet containing new data; responding to the wireless data packet, by the network device, by initiating a prescribed randomized collision avoidance method requiring the network device to first wait at least a first half of a prescribed minimum contention interval before attempting transmission at a randomized position within a second half of the prescribed minimum contention interval; selectively retransmitting, by the network device, the wireless data packet based on determining, at the randomized position, that the network device has not received a prescribed number of copies of the wireless data packet; and selectively sending, by the network device to a path computation element in the data network, a message requesting membership in a dominating set in response to transmission of the wireless data packet by the network device.

Abstract: In one embodiment, a supervisory device in a network forms a virtual access point (VAP) for a node in the network. A set of access points (APs) in the network are mapped to the VAP as part of a VAP mapping and the node treats the APs in the VAP mapping as a single AP for purposes of communicating with the network. The supervisory device receives measurements from the APs in the VAP mapping regarding communications associated with the node. The supervisory device identifies a movement of the node based on the received measurements from the APs in the VAP mapping. The supervisory device adjusts the set of APs in the VAP mapping based on the identified movement of the node.

Abstract: In one embodiment, a supervisory device in a network assigns different access points in the network to different access point groupings. Each of the different access point groupings uses a different network path to communicate with a given endpoint in the network. The supervisory device selects at least one of the access points in each of the different access point groupings for mapping to a virtual access point (VAP) for a node in the network as part of a VAP mapping. The supervisory device instructs the selected access points to form a VAP for the node. The node treats the access points in the VAP mapping as a single access point for purposes of communicating with the network.

Abstract: In one embodiment, a device in a network receives data associated with a particular location. The device determines when the device is at the particular location by monitoring a local position of the device relative to the particular location. The device identifies a node in the network as being co-located with the device at the particular location. The device shares the data with the identified node based on the device and the node being co-located at the particular location.

Abstract: In one embodiment, a device in a network receives a notification from a neighbor of the device indicative of a child node of the device requesting a parent change from the device to the neighbor. The device updates an existing routing path from the device to the child node to be routed through the neighbor, in response to receiving the notification from the neighbor. The device receives an instruction to remove the updated routing path from the device to the child node through the neighbor. The device removes the updated routing path from the device to the child node, in response to receiving the instruction to remove the updated routing path.

Abstract: In one embodiment, a device in a network receives one or more packets that are part of a traffic flow. The device provides a sample packet to a path computation element (PCE) that includes a signature that uniquely identifies the traffic flow. The device receives a traffic flow policy for the traffic flow from a policy engine and enforces the traffic flow policy for the traffic flow.

Abstract: In one embodiment, an intermediate node in a contention-based shared-media computer network determines a scheduled window within which a packet (with an assigned priority) should be transmitted by the intermediate node. In particular, the intermediate node may specifically determine whether an actual transmission time is prior to, during, or after the window, and sets a priority of the packet as either i) a reduced priority when the actual transmission time is prior to the window, ii) the assigned priority when the actual transmission time is during the window, or iii) an augmented priority when the actual transmission time is after the window. As such, the intermediate node may then transmit the packet from the intermediate node with the set priority at the actual transmission time.
