Simulation parameters.

Type	Parameters	Values
Simulation parameters	Network Size	Max 10000

		For Pareto churn	2,000 s
Common architecture parameters	Fix finger delay	120 s
	Stabilization delay	60 s
	Successor list size	4
Node distribution	Percentage of super peers	5
	Percentage of regular peers	95
	Percentage of malicious peers in regular peers for churn attack scenario only	10	20	30		40	50
