A Survey on Identification of Critical Nodes in Ad Hoc Network

To monitor and protect Ad Hoc networks more efficiently, it is very necessary to identify critical nodes in the network. At present, the evaluation of the critical degree of nodes is mainly carried out from two aspects: one is to equate the importance of nodes with the criticality of nodes; the other is to equate the damage to the network caused by node deletion with the criticality of nodes. This paper gives an overview of relevant methods.
