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 "authenticated preambles for denial of service mitigation in lpwans"):
  Abstract: In this article we introduce authentication preambles as a mechanism to mitigate battery exhaustion attacks in LPWAN networks. We focus on the LoRaWAN technology as an exponent of industrial LPWANs. We analyze the impact of DoS attacks in Class B deployments and implement authentication preambles to limit attacker options when forcing nodes to overhear class B beacons. The article presents realistic results demonstrating significant energy savings (91% energy saving when a network is attacked) versus a 4% energy overhead of the mechanism in normally operating networks.

Includes members:
  Member "selective jamming of lorawan using commodity hardware":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "i send therefore i leak information leakage in low power wide area networks")
  Member "low power wide area network analysis can lora scale":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "performance analysis of single cell adaptive data rate enabled lorawan")
