[ns] AQM for emergency traffic

2009-04-25 Thread Sir Fantomas

Hi all,
I'm doing a little project about the incorporation of user priority in active 
queuing management for emergency communication. I have just read the document 
Design and Analysis of Multi-Level Active Queue Management Mechanisms for 
Emergency Traffic of Cory Beard and I found it very interesting. 
Does anyone have the NS2 code he used for the simulation?
Best Regards
