Abstract: In one embodiment, a network node provides a time slotted channel hopping (TSCH) schedule to one or more child nodes of the network node. The TSCH schedule includes one or more mandatory routing protocol report time slots. The network node receives routing protocol reports from the one or more child nodes according to the TSCH schedule. The network node aggregates the received routing protocol reports into an aggregated routing protocol report. The network node provides the aggregated routing protocol report to a parent of the network node during a time slot that is subsequent to the one or more mandatory time slots for the one or more child nodes.

Abstract: In one embodiment, a device in a network receives an indication of an appropriation and defense time slot for a set of time slots in a channel hopping schedule. The device appropriates ownership of the set of time slots using an appropriation window of the appropriation and defense time slot. The device receives an appropriation request from a second device during the appropriation window. In response to receiving the appropriation request, the device sends a defense notification during a defense window of the appropriation and defense time slot.

Abstract: A system includes an on-board unit (OBU) in communication with an internal subsystem in a vehicle on at least one Ethernet network and a node on a wireless network. A method in one embodiment includes receiving a message on the Ethernet network in the vehicle, encapsulating the message to facilitate translation to Ethernet protocol if the message is not in Ethernet protocol, and transmitting the message in Ethernet protocol to its destination. Certain embodiments include optimizing data transmission over the wireless network using redundancy caches, dictionaries, object contexts databases, speech templates and protocol header templates, and cross layer optimization of data flow from a receiver to a sender over a TCP connection. Certain embodiments also include dynamically identifying and selecting an operating frequency with least interference for data transmission over the wireless network.

Abstract: Techniques for varying locations of virtual networks associated with endpoints using Network Address Translation (NAT), Mobile Internet Protocol (MIP), and/or other techniques in conjunction with Domain Name System (DNS). Rather than having DNS provide a client device with an IP address of an endpoint device, such as a server, the DNS instead returns a virtual IP (VIP) address that is mapped to the client device and the endpoint device. The VIP address may be selected based on a number of factors (e.g., power usage, privacy requirements, virtual distances, etc.). In this way, IP addresses of servers are obfuscated by a virtual network of VIP addresses that can be periodically rotated and/or load balanced. The client device may then communicate data packets to the server using the VIP address as the destination address, and a virtual network service that works in conjunction with DNS can convert the VIP address to the actual IP address of the server using NAT and forward the data packet onto the server.

Abstract: Techniques for using Prefix Address Translation (PAT), Mobile Internet Protocol (MIP), and/or other techniques to anonymize server-side addresses in data communications. Rather than allowing a server and/or endpoint have visibility of a client IP address of a client device accessing the server and/or endpoint, a virtual network service instead returns a PAT IP address that is mapped to the client device and/or the endpoint device. In this way, IP addresses of clients devices are obfuscated by the virtual network. The client device may then communicate data packets to the server and/or endpoint using the PAT IP address as the source address, and the virtual network service that works in conjunction with the server and/or endpoints can convert the PAT IP address to the actual IP address of the client for return packets using PAT and forward the return packet onto the client device.

Abstract: Described herein are devices, systems, methods, and processes for improving retransmissions in wireless communication networks by distinguishing between temporal interference and longer-term radio frequency (RF) condition issues. The fact that the access point (AP) does not usually move may be leveraged, and a machine learning process can be utilized to learn and adapt to the RF conditions in the cell. The AP records various parameters for each frame received from client devices and uses this data to build a pairwise temporal matrix. Machine learning models are trained using these parameters, enabling the AP to compute the likely efficient set of modulation and coding schemes (MCSs) at each static position and along moving positions. The AP can then adapt its MCS accordingly for the downlink traffic and provide the client device with recommended MCSs for upcoming uplink transmissions. Accordingly, the retry count at the client devices can be reduced.

Abstract: Systems, methods, and computer-readable media are provided for securely advertising autoconfigured prefixes in a cloud environment. In some examples, a method can include, receiving, by a first router, an indication of an available network address prefix. In some aspects, the method can also include selecting, by the first router, a first network address prefix that is within the available network address prefix, wherein the first network address prefix provides at least one route to one or more network elements associated with the first router. In some cases, the method may further include sending, to a second router, a message including a stub registration option that indicates the first network address prefix.

Abstract: Methods and systems are described herein for detecting deviations from an expected power profile of a device. The method comprises: retrieving a manufacturer usage description (MUD) associated with the device. The MUD includes a power profile associated with the device. An expected power consumption parameter can be determined from the power profile. The method may further comprise monitoring an actual power consumption parameter of the device and comparing the expected power consumption parameter to the actual power consumption parameter. The method may further comprise determining a deviation between the power consumption parameter and the expected power consumption indicated in the power profile, and outputting a notification when the deviation is equal to or greater than a threshold value.
