After a specific time suppose for the first 5s of my simulation the payloads travel back to the consumer at a normal rate after 5s, I want producer 6 to turn into a hijacker and hijack the incoming interests. If I can do that can anyone please guide me on how? Thank you so much for your help in advance. 

two clarification questions: 

1/ do all your 3 producers announce the same, or different name prefixes?

2/ if each of them announce different prefixes, by "hijacking" do you mean #6 will announce other nodes's prefix?

NDN routing authenticates all prefix announcements, preventing a node from announcing any prefix that does not belong to it.
