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 "synchronous relaying of sensor data"):
  Abstract: In this paper we have put forth a novel methodology to relay data obtained by inbuilt sensors of smart phones in real time to remote database followed by fetching of this data . Smart phones are becoming very common and they are laced with a number of sensors that can not only be used in native applications but can also be sent to external nodes to be used by third parties for application and service development.

Includes members:
  Member "study of encryption and decryption of wave file in image formats":
    also connected through other hyperedges:
      (none)
  Member "ant colony based routing for mobile ad hoc networks towards improved quality of services":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "multipath routing of fragmented data transfer in a smart grid environment")
  Member "sleep deprivation attack detection in wireless sensor network":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "a novel countermeasure technique to protect wsn against denial of sleep attacks using firefly and hopfield neural network hnn algorithms")
  Member "grid security and integration with minimal performance degradation":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "increasing security in cloud environment")
