Center node: "wireless resilient routing reconfiguration"
  Abstract: Mobile wireless networks are intrinsically more prone to link congestion and outright failures than wired networks. In this paper, we elaborate the resilient routing reconfiguration method of \cite{WangEtAl} and generalize it to accomodate point-to-multipoint links and wireless networks. By reframing link failures as traffic uncertainties, this technique allows essentially instantaneous rerouting around arbitrary link failures while preventing congestion. We then illustrate this approach on a realistic model wireless network of 34 nodes and 104 links and identify a critical bottleneck.

Connected through hyperedge HE-1 (induced by source paper "fast multipole networks"):

    - "decentralized connectivity preserving deployment of large scale robot swarms"
    - "distributed cohesive control for robot swarms maintaining good connectivity in the presence of exterior forces"
    - "petascale turbulence simulation using a highly parallel fast multipole method on gpus"
    - "a tuned and scalable fast multipole method as a preeminent algorithm for exascale systems"
