    Abstract: In one embodiment, the locations of a plurality of network devices in a low power and lossy network (LLN) are determined along an intelligent wire. One or more neighboring devices for each network device in the plurality are identified based on the locations of the network devices along the intelligent wire. A communication schedule for the network devices is determined that prevents neighboring devices along the intelligent wire from transmitting on the same frequency. The network devices are assigned to communication time slots based on the communication schedule. The network devices are also assigned frequency offsets based on the communication schedule.

    Abstract: In one embodiment, an intermediate node in a contention-based shared-media computer network determines a scheduled window within which a packet (with an assigned priority) should be transmitted by the intermediate node. In particular, the intermediate node may specifically determine whether an actual transmission time is prior to, during, or after the window, and sets a priority of the packet as either i) a reduced priority when the actual transmission time is prior to the window, ii) the assigned priority when the actual transmission time is during the window, or iii) an augmented priority when the actual transmission time is after the window. As such, the intermediate node may then transmit the packet from the intermediate node with the set priority at the actual transmission time.

    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 Network Address Translation (NAT), Mobile Internet Protocol (MIP), and/or other techniques in conjunction with Domain Name System (DNS) to anonymize server-side addresses in data communications and verify an authenticity of a client device attempting to use a virtual IP (VIP) address. 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 VIP address that is mapped to the client device and the endpoint device. 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 verify an authenticity of the client device and convert the VIP address to the actual IP address of the server using NAT and forward the data packet onto the server.

    Abstract: In one embodiment, a device registers with a controller for a mesh of overhead access points. The device receives, from the controller, a communication schedule for the device. The device generates a message to be sent to the mesh of overhead access points. The device transmits, according to the communication schedule, the message as a beam cone directed substantially upward relative to the device towards the mesh of overhead access points. The message is received and relayed by one or more particular access points in the mesh without the device previously performing a wireless association exchange with those one or more particular access points.
