Abstract: Learning-based service migration in mobile edge computing may be provided. First, a service migration policy may be created for a network that includes a plurality of edge clouds configured to provide a service to users. Next, a movement of a user receiving the service from a source edge cloud may be detected. The source edge cloud may be associated with a first area and the detected movement may be from the first area to a second area. Then, the service migration policy may be applied to determine whether to migrate the service for the user from the source edge cloud. In response to determining to migrate the service, a target edge cloud may be identified and the service for the user may be migrated from the source edge cloud to the target edge cloud. The service migration policy may then be updated based on a success of the migration.

Abstract: Embodiments herein describe a network device (e.g., an access point) that dynamically arranges multi-user (MU) multiple input multiple output (MIMO) compatible client devices into MU-MIMO groups. That is, the network device uses network metrics and historical data to change the assignment of client devices in the MU-MIMO groups which may improve MU-MIMO efficiency by reducing the amount of power that leaks between the clients devices in the group. In one embodiment, the AP identifies a MU-MIMO group based on a performance evaluation such as evaluating network metric or determining if the group is underutilized. The AP can replace the identified MU-MIMO group with a substitute MU-MIMO group where the substitute MU-MIMO group is selected based on historical data corresponding to the client devices assigned to the substitute MU-MIMO group.

Abstract: An example method is provided in one example embodiment and includes receiving performance metric information from a plurality of small cell radios, wherein the performance metric information includes, at least in part, a number of user equipment that are to be scheduled on a first type and a second type of subframes for each small cell radio; determining resource allocation parameters for the plurality of small cell radios; exchanging interference information between two or more small cell radios of the plurality of small cell radios that includes an indication of whether a particular small cell radio is interfering with or is interfered by another small cell radio of the two or more small cell radios; and scheduling downlink resource transmissions on the first type and the second type of subframes for user equipment served by the two or more small cell radios.

Abstract: In one embodiment, a system includes a processor to determine a number P of how many multi-user groups are to be formed to promote airtime fairness for N client devices in which each one client device of the N client devices will be equally represented in the to-be-formed multi-user groups and in which each of the to-be-formed groups is to be actively considered by a scheduler for transmission purposes, the N client devices being associated with N wireless connections with an access point having multi-user simultaneous communication multiple-input multiple-output technology, define P multi-user groups with each one multi-user group of the P multi-user groups having a capacity for M client devices from the N client devices, N being greater than M, and allocate the N client devices to the P multi-user groups with each one client devices of the N client devices being equally represented in the P multi-user groups.
