Abstract: Methods are provided for selectively depowering any device(s) that seem unnecessarily redundant to strike a balance between resiliency and sustainability to reduce energy costs. The analysis may include a current application mix in use on network paths. For example, a policy may require that at least two available paths are actively energized when real-time collaboration apps are running. Examples of a real-time collaboration app may be data mining in an online database stored elsewhere in the network or holding a video conference call. This double path redundancy can deliver increased application availability. And, in instances where just web/email are actively running, then a backup path that may be energized in less than a second, if a primary path loses connectivity. This lower-power method can also provide increased application availability.

Abstract: In one embodiment, a mobile system scans wireless channels for any upcoming access points using a dedicated monitor radio of the mobile system. The mobile system identifies a particular wireless channel in use by an upcoming access point. The mobile system notifies a second radio of the mobile system of the particular wireless channel. The mobile system performs a handoff between a current access point and the upcoming access point in part by switching the second radio of the mobile system to the particular wireless channel of the upcoming access point.

Abstract: Time Sensitive Networking (TSN) in wireless environments may be provided. First, a Radio Frequency (RF) profile associated with a station may be received by a computing device. Next, a number of Transmit Opportunities (TxOPs) to use for transmitting data between an Access Point (AP) and the station based on the received RF profile may be determined. The determined number of TxOPs may then be provided to a wireless controller associated with the AP.

Abstract: A backscatter communication device assistant may be provided. A computing device may designate a client device as a backscatter communication device assistant. Next, a report indicating a location of a backscatter communication device may be received from the backscatter communication device assistant. Then the backscatter communication device may be caused to receive energy. Data originating from the backscatter communication device may then be received.

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: Disclosed herein are systems, methods, and computer-readable media for forwarding packets between parallel IPv4 networks that includes encapsulating an IP packet to include an outer header and an inner header. The IP packet is routed to a shaft spanning a subset of addresses within the source realm. Upon reaching the shaft in the source realm, a first swap of the inner header and the outer header of the IP packet is performed. The IP packet is forwarded inside the shaft from the source realm to the destination realm. Upon reaching the destination realm, a second swap of the inner header and the outer header of the IP packet is performed. The IP packet is forwarded in the destination realm to the destination node.

Abstract: A container includes a user program and data generated by the user program within a regulatory jurisdiction. Before the container leaves the regulatory jurisdiction, the data is validated by the jurisdiction to ensure the data complies with privacy laws of the jurisdiction. Upon ingress to a second regulatory jurisdiction, the data is signed locally to provide for confirmation that the data can leave the second regulatory jurisdiction, since it was not generated within the second jurisdiction. By allowing the user program to move from the first regulatory jurisdiction to a second regulatory jurisdiction, the disclosed embodiments overcome limitations in current solutions that restrict access to local data based on what a public application programming interface (API) can provide. By operating within the regulatory jurisdiction, albeit subject to access controls imposed by that jurisdiction, flexibility in the processing of sensitive data is improved.

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.
