human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "a proactive design to detect denial of service attacks using snmp mib icmp variables"
  Abstract: Denial of Service (DOS) attack is one of the most attack that attract the cyber criminals which aims to reduce the network performance from doing its intended functions. Moreover, DOS Attacks can cause a huge damage on the data Confidentiality, Integrity and Availability. This paper introduced a system that detects the network traffic and varies the DOS attacks from normal traffic based on an adopted dataset. The results had shown that the adopted algorithms with the ICMP variables achieved a high accuracy percentage with approximately 99.6 in detecting ICMP Echo attack, HTTP Flood Attack, and Slowloris attack. Moreover, the designed model succeeded with a rate of 100 in varying normal traffic from various DOS attacks.
