  • METHOD AND SYSTEM FOR REOPTIMIZING UNMANNED AERIAL VEHICLE FORMATION COMMUNICATION TOPOLOGY BASED ON MINIMUM COST ARBORESCENCE
    Publication number: 20170347285
    Abstract: A method and a system for reoptimizing unmanned aerial vehicle formation communication topology based on minimum cost arborescence are used for optimizing reconstructed UAV formation communication topology after a communication failure occurs on the UAVs in the formation. The method includes calculating a first communication cost of the reconstructed UAV formation communication topology; comparing the first communication cost with a target communication cost for the minimum cost arborescence of the formation communication diagram under a predetermined state; when the first communication cost is greater than the target communication cost for the minimum cost arborescence of the formation communication diagram under the predetermined state, optimizing the reconstructed UAV formation communication topology through a predetermined strategy.

  • DECENTRALIZED, HIERARCHICAL, AND OVERLAY-DRIVEN MOBILITY SUPPORT ARCHITECTURE FOR INFORMATION-CENTRIC NETWORKS
    Publication number: 20170339228
    Abstract: An anchor server in an information-centric network (ICN) receives registration and deregistration requests from one or more producers in the ICN. In response to a producer initially registering, the anchor server stores records associating the producer with content available from the producer via a first point of attachment. In response to the producer deregistering, the records are marked as deactivated. While the records are deactivated, requests for the content from consumers may be queued. In response to the producer reregistering as being connected to the ICN via a second point of attachment, the queued requests are forwarded to the producer via the second point of attachment.
