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 "a performance evaluation tool for drone communications in 4g cellular networks"):
  Abstract: We introduce a measurement tool for performance evaluation of wireless communications with drones over cellular networks. The Android software records various LTE parameters, evaluates the TCP and UDP throughput, and tracks the GPS position. Example measurement results are presented.

Includes members:
  Member "the sky is not the limit lte for unmanned aerial vehicles":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "performance analysis of mobile cellular connected drones under practical antenna configurations")
  Member "an overview of 3gpp release 15 study on enhanced lte support for connected drones":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "on the 3 d placement of airborne base stations using tethered uavs")
  Member "a telecom perspective on the internet of drones from lte advanced to 5g":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "uav communications for 5g and beyond recent advances and future trends")
  Member "measurement based modelling of lte performance in dublin city":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "low delay random linear coding and scheduling over multiple interfaces")
