Abstract: Techniques for detecting and/or confirming a Man-in-The-Middle (MiTM) attack using Fine Timing Measurement (FTM) are provided. In one aspect, a FTM exchange is initiated between a second station and a first station to detect or confirm a MiTM attack in a network in which a MiTM is positioned between the first station and a third station. The MiTM attack is detected or confirmed, or both, based at least in part on FTM information determined during the FTM exchange.

Abstract: In one embodiment, a device determines a physical location of a mobile client of wireless network. The device performs a frequency lookup for the mobile client from an AFC service using the physical location of the mobile client. The device selects a frequency to be used by the mobile client based on the frequency lookup. The device causes the mobile client to use the frequency to communicate with the wireless network.

Abstract: Systems and techniques for dynamically optimizing a wireless network topology to minimize energy consumption while preserving user quality of experience (QoE) are described. An example technique includes determining a set of applications that have a target service level agreement (SLA). Network traffic is monitored from the set of applications being executed by one or more client STAs within a network. A topology of the network is dynamically adapted to reduce an amount of energy consumption in the network while maintaining a threshold amount of the network traffic that satisfies the target SLA, based on monitoring the network traffic.

Abstract: The present disclosure describes a wireless network in which an access point determines and selects alternative devices to make transmissions for energy harvesting purposes. The access point includes a memory and a processor communicatively coupled to the memory. The processor determines, based on a proximity of a first device to a second device, that the second device should harvest energy from a message transmitted by the first device, determines a first basic service set (BSS) color that the first device and the second device should use for the second device to harvest energy from the message, and communicates, to the first device, an instruction to use the first BSS color when transmitting the message.

Abstract: A single cluster formation technique for Ultra-Wideband (UWB) Time Difference of Arrival (TDoA) may be provided. A primary anchor may be elected from a plurality of anchors. Then a structure of a cluster formed by the plurality of anchors may be collected by the primary anchor. A Direction-Oriented Directed Acyclic Graph (DODAG) may be built for the cluster based on an uncontrolled time drift along the DODAG and weighted by a number of hops to the primary anchor.

Abstract: In one embodiment, a method comprises: receiving, by a root network device providing a DAG topology in a low power and lossy network (LLN), one or more multicast registration messages from an LLN device and identifying distinct properties of the LLN device; receiving, by the root network device, one or more multicast address group identifiers of one or more multicast streams to which the LLN device has subscribed, and associating the one or more multicast address group identifiers with the distinct properties; receiving a multicast message specifying one of the multicast address group identifiers; and generating, by the root network device, a directed multicast message having a multi-dimensional addressing data structure comprising a selected one of the distinct properties and the one multicast address group identifier, causing parent network devices in the DAG topology to selectively retransmit based on determining a child network device has the selected one distinct property.
