NS2 Models

Traffic models and applications Web, FTP, telnet, CBR, real audio

Transport protocols unicast: TCP (Reno, Vegas, etc.), UDP Multicast: SRM

Routing and queueing Wired routing, ad hoc routing and directed diffusion queueing protocols: RED, drop-tail, etc

Physical media Wired (point-to-point, LANs), wireless (multiple propag

ation models), satellite

Extending NS2 in OTcl

If you don’t want to compile Source your changes in your sim scripts

Otherwise Modifying code; recompile Adding new files (ex. tcl/mysrc/msg.tcl)

Change Makefile• NS_TCL_LIB = \

tcl/mysrc/msg.tcl \…..

Change tcl/lib/ns-lib.tcl• Class Simulator

source ../mysrc/msg.tcl…..

Recompile

66

Extending NS2 in C++

Modifying code Make depend Recompile

Adding code in new files Change Makefile (include “new files.o” in the object file

list) Make depend Recompile
