    Abstract: In one embodiment, a method comprises identifying an age of payload data in a data packet by a wireless network node configured for transmitting the data packet to a multi-hop destination via a wireless mesh network; determining by the wireless network node a schedule for the data packet reaching the multi-hop destination; and the wireless network node prioritizing queuing of the data packet for Collision Sense with Multiple Access and Collision Avoidance (CSMA-CA) based wireless transmission in the wireless mesh network based on the corresponding age, relative to the schedule and respective ages of other data packets awaiting transmission by the wireless network node to the destination, where a higher-aged data packet relative to the schedule is granted have a higher priority than a lower-aged data packet relative to the schedule.

    Abstract: In one embodiment, techniques for adaptive forward error correction (FEC) in LPWANS are disclosed. The techniques may include determining, by a process, for a block of messages transmitted through a computer network with forward error correction, whether any unrecovered data loss occurred during transmission; increasing, by the process, a level of forward error correction used to transmit through the computer network in response to unrecovered data loss; and/or decreasing, by the process, the level of forward error correction used to transmit through the computer network in response to no unrecovered data loss.

    Abstract: In one embodiment, an illustrative method herein may comprise: receiving, at a first edge device, a direct indication from a second edge device that a mobile device has moved from the first to the second edge device; determining, based on the direct indication, a first time at which the mobile device attached to the second edge device; receiving a network routing update message indicative of a routing update for the mobile device having moved to the second edge device; determining, based on the network routing update message, a second time at which convergence completed at the first edge device; and calculating a convergence time for the mobile device to be detected as having moved to the second edge device based on a difference between the first time and the second time.

    Abstract: In one embodiment, a controller identifies access points forming an overhead mesh of access points in an area, each access point comprising one or more directional transmitters each configured to transmit a beam cone in a substantially downward direction towards a floor of the area. The controller determines coverage areas on the floor of the area for the one or more directional transmitters of the access points in the overhead mesh. The controller generates, based on the coverage areas, alternating communication schedules for the access points such that a client device at any given location on the floor of the area is within range of a plurality of receiving access points in the overhead mesh and at least one transmitting access point in the overhead mesh at a certain point in time. The controller sends the communication schedules to the access points.

    Abstract: A source access network device multicasts copies of a packet to multiple core switches, for switching to a same target access network device. The core switches are selected for the multicast based on a load balancing algorithm managed by a central controller. The target access network device receives at least one of the copies of the packet and generates at least metric indicative of a level of traffic congestion at the core switches and feeds back information regarding the recorded at least one metric to the controller. The controller adjusts the load balancing algorithm based on the fed back information for selection of core switches for a subsequent data flow.
