Abstract: Disclosed are systems, apparatuses, methods, and computer-readable media for identifying a location of a wireless device. A method for identifying a location of a wireless device includes transmitting a request message to the wireless device for identifying a position of the wireless device; receiving a response message from the wireless device; determining first time information based on a time of flight (ToF) of the request message and the response message, wherein the ToF corresponds to a distance of the wireless device from the AP; receiving a second message from a second AP that includes second time information associated with the request message and the response message; receiving a third message from a third AP that includes third time information associated with the request message and the response message; and transmitting location configuration information to the wireless device for the wireless device to determine a position of the wireless device.

Abstract: Optimal coding scheme parameters may be provided. Information associated with a plurality of client devices may be received by a computing device. A map of locations of the plurality of client devices relative to an Access Point (AP) may be created based on the information. A connected dominating set of client devices within the plurality of client devices may be identified based on the map. A first client device in the connected dominating set may then be caused to relay data between the AP and a second client device comprising a client device in the plurality of client devices that is dominated by the first client device in the connected dominating set.

Abstract: A wireless client device communicates, to an access point over a secure channel, a mapping of a dynamic device address to a stable device address. By communicating the mapping, the access point is able to determine that packets received from two different device addresses originate from a common device. The access point is then able to maintain an association between the originating device and other network resources assigned or allocated to the originating device, such as IP addresses or infrastructure station address, which is used to identify the originating device to other devices outside the network in some embodiments.

Abstract: A method is provided that is performed in a wireless network to detect a rogue wireless device. The method comprises detecting a suspect wireless device in the wireless network based on messages transmitted by the suspect wireless device using a first Media Access Control (MAC) address that is also used by a valid wireless device in the wireless network. When a suspect wireless device is detected, the method next includes sending to the valid wireless device in the wireless network a request configured to cause the valid wireless device to change its MAC address. After the valid wireless device has changed its MAC address, the method involves observing messages transmitted by the suspect wireless device in the wireless network. The method then includes determining that the suspect wireless device is a rogue device when the suspect wireless device continues to transmit messages using the first MAC address.

Abstract: In one embodiment, a controller for an overhead mesh of access points in an area receives an indication from one or more access points of the overhead mesh that a client device is present in the area. The controller determines movements of the client device within the area. The controller selects a set of access points of the overhead mesh to support communications between the client device and the overhead mesh, based on the movements of the client device determined by the controller. The controller causes the controller, the set of access points to form communication schedules to support communications with the client device that do not require a prior association exchange with the client device.

Abstract: A user device connected to a wireless network maintains session persistence through a MAC address change of a user device. The user device establishes a multi-path communication session including a first subflow associated with a first MAC address for the user device. When the user device changes from the first MAC address to a second MAC address. the user device establishes a second subflow of the multi-path communication session. The second subflow is associated with the second MAC address. After establishing the second subflow associated with the second MAC address, the user device ends the first subflow associated with the first MAC address.

Abstract: Methods are provided to determine validity of a MAC address. The methods involve obtaining a media access control (MAC) address validity message that indicates a plurality of valid MAC addresses in the wireless network using a fully-exploded format or a probabilistic data structure and determining whether a MAC address is valid based on the MAC address validity message. Other methods involve obtaining a query regarding a validity of a media access control (MAC) address, determining whether the MAC address is a value included in a data set of expected values of a probabilistic data structure. The data set represents a list of MAC addresses. The other methods involve determining whether the MAC address is valid in the wireless network based on determining whether the MAC address is the value included in the data set and providing a response indicating whether the MAC address is valid.
