Quantitative Invulnerability Analysis of Artificial Spider-Web Topology Model Based on End-to-End Delay

Table 1

Variation in the network delay when the nodes in the first, second, and third layers are damaged.

Number of nodes damaged	Failure type	End-to-end delay time (s)			Delay increment (s)
		Damage of the 1st layer	Damage of the 2nd layer	Damage of the 3rd layer	Damage of the 1st layer	Damage of the 2nd layer	Damage of the 3rd layer
