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 "security threats in manets a review"):
  Abstract: Ad hoc networks are the special networks formed for specific applications. Operating in ad-hoc mode allows all wireless devices within range of each other to discover and communicate in a peer-to-peer fashion without involving central access points. Many routing protocols like AODV, DSR etc have been proposed for these networks to find an end to end path between the nodes. These routing protocols are prone to attacks by the malicious nodes. There is a need to detect and prevent these attacks in a timely manner before destruction of network services.
