Abstract: Techniques for trusted roaming between identity federation based networks. A first wireless access point (AP) receives a roaming request from a wireless station (STA), to roam from the first AP to a second AP. The first AP is associated with a first access network provider (ANP), the second AP is associated with a second ANP, and the first ANP is different from the second ANP. Authentication information relating to the STA is transmitted from the first ANP to the second ANP using a trusted connection. The trusted connection was previously established between the first ANP and the second ANP based on a query to an identity federation to which both the first and second ANP belong. The STA is de-associated from the first AP. The STA is re-associated at the second AP using the transmitted authentication information.

Abstract: Disclosed herein are a system and method for efficiently routing high-priority frames through a wireless network based on markings of the frames by a data link layer, a network layer, or an application layer in a five-layer protocol stack. When a real-time application, such as a video or gaming application, is to be sent to one or more stations in the wireless network, the access point determines the strategy for routing the high-priority frames based on the markings received from the data link, network, or application layer. Strategies include discarding non-I frames when there is congestion in the wireless network, replicating I-frames to assure reliable delivery to the stations, scheduling I-frames with preference, and moving I-frames ahead in a buffer in the access point.

Abstract: Techniques for wireless device roaming are disclosed. These techniques include identifying a wireless client entity for roaming from a first infrastructure entity to a second infrastructure entity. The techniques further include agreeing, between the client entity and the first infrastructure entity, on one or more roaming conditions defined using transition parameters for transition of a first data flow for the client entity from the first infrastructure entity to the second infrastructure entity, the one or more transition parameters including a sequence number relating to the dataflow. The techniques further include determining that a first condition defined in terms of a transition parameter of the agreed one or more roaming conditions is met, and, based on the determining, transitioning from providing the first dataflow from the first infrastructure entity to the client entity to providing the first data flow from the second infrastructure entity to the client entity.

Abstract: The present disclosure describes a combination backscatter device and methods of operation involving the combination backscatter device. An apparatus includes a passive backscatter device, an active backscatter device, and a cover. The passive backscatter device transmits a first message using energy from a wireless signal. The active backscatter device includes a first capacitor that charges using energy from a wireless signal. The cover moves over the passive backscatter device based on an amount of energy stored in the first capacitor.

Abstract: Fine Time Measurement (FTM) improvement and, specifically, trigger based FTM improvements via efficiently grouping initiators may be provided. A plurality of probe requests transmitted by a plurality of initiators is received. For each probe request, a Received Signal Strength Indication (RSSI) and Channel State Information (CSI) is determined, and a distance between an initiator and an associated responder associated with the probe request is determined based on the RSSI and the CSI. Line of Sight (LOS) or Non Line of Sight (NLOS) relationships between the plurality of initiators and one or more responders is determined based on the CSI. One or more groups of initiators is determined from the plurality of initiators based on the LOS or NLOS relationships and the distances determined for each probe request, wherein the responders and the initiators perform FTM based on the one or more groups of initiators.

Abstract: In one embodiment, a device receives discovery data generated by a plurality of networking devices in a network. The device determines, based on the discovery data, a hierarchy of layers of the network. The device receives a request by a client that is external to the network to access remotely a particular endpoint in the network. The device configures, and in response to the request, a proxy chain of remote access agents executed by a subset of networking devices from the plurality of networking devices to allow the client to access remotely the particular endpoint, each of those networking devices proxying traffic between different layers of the network.

Abstract: Techniques for delegated peer-to-peer scheduling are provided. A first peer-to-peer device determines one or more wireless channels allocated for peer-to-peer communication, and receives a request indicating a set of transmission characteristics from a second peer-to-peer device that uses the first peer-to-peer device as a communications proxy. The first peer-to-peer device schedules wireless resources of the one or more wireless channels to a plurality of peer-to-peer devices based at least in part on the set of transmission characteristics, and performs peer-to-peer communications with the second peer-to-peer device in accordance with the scheduled wireless resources.

Abstract: Aspects of the disclosure include a method and associated network device. The method includes authenticating an identity of a user of a client device after the client device is associated with an access network provider. Authenticating the identity of the user comprises receiving, from an identity provider, a credential associated with the identity, and receiving, from the identity provider, information identifying a network-based service to be applied to network traffic with the client device. The method further includes establishing, using the credential and the received information, a secure connection between the access network provider and a service provider that is capable of providing the network-based service. The method further includes receiving network traffic from the service provider. Packets of the network traffic include an assurance value that enables the client device to determine that the network-based service is being provided by the service provider.
