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 "the effect of the number of mobile nodes on varying speeds of manets"):
  Abstract: Mobile Ad hoc Networks (MANETs) are dynamic networks populated by mobile devices, or mobile nodes (MNs).TheMobile Nodes (MNs) arefreetomoveanywhere and at any time. The population of the nodes may have some influence on the mobility rate of the MNs.This paper presentssimulation results using MatLab software. The study investigates the influence of mobile nodes’ parameters such as number of nodes on the nodes speedsand nodes distribution in a given area. The results have indicated thatthe number of mobile nodes have impact on the speeds of the nodes in a location.

Includes members:
  Member "the impact of mobile nodes arrival patterns in manets using poisson models":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "comparing the impact of mobile nodes arrival patterns in manets using poisson and pareto models")
  Member "a new cluster based wormhole intrusion detection algorithm for mobile ad hoc networks":
    also connected through other hyperedges:
