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 "distributed multiuser sequential channel sensing schemes in multichannel cognitive radio networks"):
  Abstract: This paper has been withdrawn by the author due to a crucial problem associated with Figs. 2 and 3.

Includes members:
  Member "performance of joint spectrum sensing and mac algorithms for multichannel opportunistic spectrum access ad hoc networks":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "multi channel mac protocol for full duplex cognitive radio networks with optimized access control and load balancing")
  Member "sensing matrix setting schemes for cognitive networks and their performance analysis":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "analysis and optimization of random sensing order in cognitive radio networks")
  Member "throughput and collision analysis of multichannel multistage spectrum sensing algorithms":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "multiple antenna cyclostationary spectrum sensing based on the cyclic correlation significance test")
  Member "optimal medium access control in cognitive radios a sequential design approach":
    also connected through other hyperedges:
      (none)
  Member "cognitive medium access exploration exploitation and competition":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "action manipulation attacks against stochastic bandits attacks and defense")
