human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "state of the art in power line communications from the applications to the medium"):
  Abstract: In recent decades, power line communication (PLC) has attracted considerable attention from the research community and industry, as well as from regulatory and standardization bodies. In this paper, we provide an overview of both narrowband and broadband systems, covering potential applications, regulatory and standardization efforts, and recent research advancements in channel characterization, physical layer performance, medium access, and higher layer specifications and evaluations. We also identify the areas of current and further study that will enable the continued success of PLC technology.

Includes members:
  Member "on efficiency and validity of previous homeplug mac performance analysis":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "how csma ca with deferral affects performance and dynamics in power line communications")
  Member "a novel approach to the statistical modeling of wireline channels":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "on the capacity of mimo broadband power line communications channels")
  Member "for the grid and through the grid the role of power line communications in the smart grid":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "the secrecy capacity of gaussian mimo channels with finite memory full version")
