Abstract: A method includes instructing, by a WiFi access node, a first device to communicate using an uplink frequency band with a first uplink power. The method also includes instructing, by the WiFi access node, a second device to communicate using the uplink frequency band with a second uplink power different from the first uplink power.

Abstract: Optimal determination of a Wireless Local Area Network (WLAN) sounding method and system may be provided. An Access Point (AP) selects a subchannel for the partial sounding. The AP then sounds the selected subchannel. A client station responds with Channel State Information (CSI). The AP can receive the CSI, from the client station, in response to the sounding. Based on the CSI from the selected subchannel, the AP extrapolates the CSI to determine predicted CSI for a wider bandwidth channel.

Abstract: Aspects described herein include a method for use with an access point (AP). The method comprises inspecting control frames received from a rogue AP, characterizing an intrusion by the rogue AP using one or more spatial reuse parameters included in the control frames, and selecting a defensive posture for the AP based on the characterization.

Abstract: Learning-based service migration in mobile edge computing may be provided. First, a service migration policy may be created for a network that includes a plurality of edge clouds configured to provide a service to users. Next, a movement of a user receiving the service from a source edge cloud may be detected. The source edge cloud may be associated with a first area and the detected movement may be from the first area to a second area. Then, the service migration policy may be applied to determine whether to migrate the service for the user from the source edge cloud. In response to determining to migrate the service, a target edge cloud may be identified and the service for the user may be migrated from the source edge cloud to the target edge cloud. The service migration policy may then be updated based on a success of the migration.

Abstract: In one embodiment, a management entity monitors for a change in a convergence rate of spatio-temporal compressive sensing measurements from a plurality of sensors in a sensor network operating according to a measurement matrix up to a halting criterion, and if the change is below a given threshold, determines whether the change is due to impulse noise or due to continued sensed measurements. If continued sensed measurements, the management entity initiates a single-dimensional compressive sensing in a spatial domain at regular time intervals, and identifies and tracks gradient clusters. In response to a change in joint spatio-temporal sparsity of tracked nodes of the gradient clusters, the management entity can then determine an updated measurement matrix based on the joint spatio-temporal sparsity of tracked nodes while satisfying one or more operating parameters, and directs at least certain sensors of the plurality of sensors to operate according to the updated measurement matrix.

Abstract: In one embodiment, a process tracks measured carrier frequency offsets (CFOs) of identified transmitters over a period of activity of the identified transmitters, and determines predicted CFOs for the identified transmitters and predicted transmitter behavior as a probability of specific transmitters of the identified transmitters being active at given times based on the activity of the identified transmitters. The process may then determine, based on the predicted CFOs and predicted transmitter behavior, CFO ranges that a receiver should expect for upcoming packets, and instructs the receiver to use the CFO ranges as a prioritized list of dynamically selected CFOs to use to extract single or colliding packets from among potential interferences using frequency demodulation.
