human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "an asymptotically optimal push pull method for multicasting over a random network"
  Abstract: We consider allcast and multicast flow problems where either all of the nodes or only a subset of the nodes may be in session. Traffic from each node in the session has to be sent to every other node in the session. If the session does not consist of all the nodes, the remaining nodes act as relays. The nodes are connected by undirected links whose capacities are independent and identically distributed random variables. We study the asymptotics of the capacity region (with network coding) in the limit of a large number of nodes, and show that the normalized sum rate converges to a constant almost surely. We then provide a decentralized push-pull algorithm that asymptotically achieves this normalized sum rate without network coding.

Connected through hyperedge HE-1 (induced by source paper "network coding for real time wireless communication for automation"):
  with members:
    - "real time cooperative communication for automation over wireless"
    - "what will 5g be"
    - "quasi static multiple antenna fading channels at finite blocklength"
