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 "blisp enhancing backscatter radio with active radio for computational rfids"):
  Abstract: We introduce the world's first hybrid radio platform which combines the strengths of active radio (long range and robustness to interference) and Computational RFID (CRFID) (low power consumption). By a set of laboratory experiments, we show that our hybrid radio — composed of Wireless Identification and Sensing Platform (WISP) CRFID radio and Bluetooth Low Energy (BLE) — obtains higher goodput than WISP and lower energy consumption than BLE, both as stand-alone platforms.

Includes members:
  Member "gondola a parametric robot infrastructure for repeatable mobile experiments":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "wisent robust downstream communication and storage for computational rfids")
  Member "powering the next billion devices with wi fi":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "towards flexible wireless charging for medical implants using distributed antenna system")
