Hi,
 I want to know about manet & p2p filesharing application in nS2 simulator environment.currently i am searching for the p2p protocols Mobile Peer to Peer (MPP) & Optimised Routing Independent Overlay Network(ORION) protocol which are obviously application layer protocol. I want to interface this application layer protocol to 
NS2 physicaql/network layer protocols.I don't have much knowledge about NS2 till now So also tell me about the links & study material which I desperately need for clearing my concepts regarding the same.
Please tell me where can I get these above mentioned protocols to interface with the NS2.More information regarding this will be greatly appreciated

With thanks,
Mahesh
