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
  propagation models), satellite

Extending NS2 in OTcl

• If you dont 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

6
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
