Abstract: Systems, methods, and computer-readable media for enforcing data sovereignty policies in a cloud environment are provided. An example method can include sending, by a cloud provider, to a government entity associated with a geographic area, a request for device certificates for nodes located within the geographic area; receiving device certificates for the nodes; creating a data sovereignty policy specifying that data associated with the government entity must be stored on nodes located within the geographic area; based on the device certificates, verifying those of the nodes that comply with the data sovereignty policy; and storing the data associated with the government entity on those of the nodes verified to comply with the data sovereignty policy.

Abstract: The disclosed technology relates to a process for metered training of fog nodes within the fog layer. The metered training allows the fog nodes to be continually trained within the fog layer without the need for the cloud. Furthermore, the metered training allows the fog node to operate normally as the training is performed only when spare resources are available at the fog node. The disclosed technology also relates to a process of sharing better trained machine learning models of a fog node with other similar fog nodes thereby speeding up the training process for other fog nodes within the fog layer.

Abstract: A location server collects from access points at known locations in a venue, which is represented by grid locations defined by parameters accessible to the location server, (i) ultra wideband (UWB) location measurements for a UWB location technology based on UWB transmissions from mobile devices in the venue, and (ii) non-UWB location measurements for non-UWB location technologies based on non-UWB transmissions from the mobile devices. The location server associates the non-UWB location measurements for the non-UWB location technologies with the grid locations, using the UWB location measurements as reference measurements. The location server populates location calibration records for the grid locations of the venue with the non-UWB location measurements associated with the grid locations. The location server calibrates the non-UWB location technologies at the grid locations based on the non-UWB location measurements in the location calibration records associated with the grid locations.

Abstract: Techniques for a network controller associated with a firewall service to determine a network policy based on operational tolerances associated with a device, and cause the network policy to be provisioned at the firewall service where control commands, such as, for example, supervisory control and data acquisition (SCADA) commands, may be allowed or denied transmission to the device based on the operational tolerance(s) associated with the device. In some examples, the network controller may be configured as a manufacturer usage description (MUD) controller configured to transmit a MUD uniform resource identifier (URI), emitted by the device, to a MUD file server associated with the manufacturer of the device. The MUD file may be enhanced to include the operational tolerances associated with the device and transmitted back to the MUD controller where it may be parsed to determine a corresponding network policy.

Abstract: Techniques for utilizing a cloud service to compute an end-to-end SLA-aware path using dynamic software-defined cloud interconnect (SDCI) tunnels between a user device and an access point-of-presence (POP) node and inter-POP tunnels of the SDCI. The cloud service may include a performance aware path instantiation (PAPI) component including a POP database for storing performance metrics associated with the POPs of the SDCI, an enterprise policy database for storing user specific policies, and/or a path computation component. The path computation component may compute the path, based on the user specific policies, performance metrics associated with the POP nodes, and/or real-time contextual data associated with the user device and/or destination device. The path may include a first tunnel between the user device and the most optimal access POP node of the SDCI and a second tunnel between the access POP node, through the internal POP nodes, and to the destination device.

Abstract: Presented herein are techniques for scheduling Ultra-Wideband (UWB) anchors and mobile devices for client ranging. A control device can determine respective ranging priorities for a plurality of mobile devices, which are each assigned to at least one UWB anchor. The control device can obtain at least one collision mapping identifying, for a respective pair of the mobile devices, a collision probability that a UWB signal associated with a ranging procedure involving a first mobile device of the respective pair will collide with a UWB signal associated with a ranging procedure involving a second mobile device of the respective pair. The control device can establish a ranging schedule for the mobile devices and UWB anchors based on the respective UWB ranging priorities and the collision mapping(s). The control device can send at least one command to cause UWB ranging procedures to be performed according to the ranging schedule.

Abstract: Methods are provided in which a user device connects a participant to a collaboration session in which the participant communicates with at least one other participant using audio and/or video, which is distributed in a media stream to the at least one other participant via a respective user device. In these methods, the user device detects at least one of an object within a space that is included in the video and an audio signal and selectively filters the media stream to exclude the object or a portion of the audio signal based on at least one of participant list information, learned background information, or learned voices of participants of the collaboration session.

Abstract: A computer-implemented method includes first collecting, from wireless devices at known locations in a venue, first ultra wideband (UWB) location measurements obtained using a first location technique based on first UWB transmissions made by a mobile device at a first rate. The method also includes second collecting, from the wireless devices, second UWB location measurements obtained using a second location technique based on second UWB transmissions made by the mobile device at a second rate. The method further includes detecting that the mobile device is in a first UWB coverage hole for the venue with respect to the first UWB location measurements based on a first UWB coverage hole criterion. The method also includes, based on detecting, increasing the second rate relative to the first rate to obtain additional second UWB location measurements using the second location technique to compensate for the first UWB coverage hole.

Abstract: In one embodiment, a method comprises: determining, by a constrained network device in a low power and lossy network (LLN), a self-estimated density value of neighboring LLN devices based on wirelessly receiving an identified number of beacon message transmissions within an identified time interval from neighboring transmitting LLN devices in the LLN; setting, by the constrained network device, a first wireless transmit power value based on the self-estimated density value; and transmitting a beacon message at the first wireless transmit power value, the beacon message specifying the self-estimated density value, a corresponding trust metric for the self-estimated density value, and the first wireless transmit power value used by the constrained network device for transmitting the beacon message.
