Abstract: In one embodiment, a technique for information sharing among dynamically grouped vehicles is provided that illustratively comprises making, by a first vehicle of a first plurality of vehicles, a determination that the first plurality of vehicles is a convoy of vehicles traveling as a group; sending, by the first vehicle, a group identifier that is indicative of the convoy and of each of the plurality of vehicles to an access point in communication with the first vehicle; authenticating, by the first vehicle, with the access point using the group identifier; and exchanging, by the first vehicle, first vehicular data with the access point using a first connection of a plurality of connections assigned to the group identifier.

Abstract: In one embodiment, a device in a network determines behavioral profiles of a plurality of nodes in the network. The behavioral profile for a particular node indicates whether the node is an occasional transmitter or a periodic transmitter. The device identifies similarly behaving nodes based on their behavioral profiles. The device assigns groups of the nodes to uplink transmission windows based on their behavioral profiles. The similarly behaving nodes that are periodic transmitters are assigned to the same uplink transmission windows and similarly behaving nodes that are occasional transmitters are assigned to different uplink transmission windows. The device controls the plurality of nodes to use their assigned uplink transmission windows via target wake time values sent to the plurality of nodes.

Abstract: In one embodiment, a process determines how often client devices roam from a given access point (AP) to each particular neighbor AP of a plurality of neighbor APs of the given AP, and correspondingly determines a roaming distance from the given AP to each particular neighbor AP, the roaming distance being shorter for neighbor APs roamed to more often, and longer for neighbor APs roamed to less often, within a given interval. Successful but temporary roams to the plurality of neighbor APs may also be detected and removed from consideration in the roaming distance to that particular neighbor AP. The process then generates a proximity list of one or more of the neighboring APs having the shortest roaming distances, and feeds the proximity list to the given AP to cause the given AP to provide the proximity list to client devices for optimized client roaming.

Abstract: Presented herein are techniques for optimizing spectral efficiency in a network. One or more metrics of one or more wireless access points that enable one or more wireless client devices to connect to a wireless network are monitored. The one or more metrics reflect a level of client device activity. Based on the one or more metrics, the level of client device activity is determined to require a change in a number of the one or more wireless access points that are active to serve the one or more wireless client devices. The one or more wireless access points are activated or deactivated to improve a spectral efficiency of the wireless network.

Abstract: In one example, a path computation element of a network configured for segment routing receives, from a plurality of path computation clients in the network, segment identifiers identifying a destination segment. A particular type of network traffic is destined for the destination segment. Based on the segment identifiers identifying the destination segment, the path computation element determines that the destination segment is a destination for the particular type of network traffic. The path computation element receives, from the plurality of path computation clients, information indicating fatigue states for segments of the network. The fatigue states are associated with the particular type of network traffic. If the fatigue states satisfy one or more conditions, the path computation element instructs the plurality of path computation clients to route the particular type of network traffic so as to proactively mitigate one or more fatigue-affected segments in the network.

Abstract: An example method is provided in one example embodiment and may include gathering current wireless local area network (WLAN) data for a WLAN, wherein the WLAN data comprises network data, Radio Frequency (RF) data, and transmission data for a plurality of user equipment (UE) operating within the WLAN; generating a plurality of color maps; merging the plurality of color maps to generate a combined color map; and calculating a predicted application score for at least one UE operating within the WLAN based, at least in part, on application of the combined color map to a trained statistical model that represents linking relationships between the WLAN data gathered for the WLAN and a plurality of possible application scores for the plurality of UE. The plurality of color maps can include an RF color map, a transmission color map, and a Quality of Service color map.
