  1. Including Your Modules into NS 2 by TeerawatIssariyakul http://www.ns2ultimate.com March 2010 http://www.ns2ultimate.com

  2. Assumptions and Objectives • You have developed NS2 modules in one or more of the following 3 file types: • What you would like to do is to incorporate these files into NS2 http://www.ns2ultimate.com

  3. Key step • Go to your ns home directory (e.g., nsallinone-2.35-RC3/ns-2.35). • Look for a file called “Makefile”. • Use your favorite editor to edit the file (I will explain the details in the next slides). • Run “make” at the command prompt under your ns home directory. • You’re done. You should be able to invoke your new modules defined in .cc, .h, and .tcl from the NS prompt. http://www.ns2ultimate.com

  4. Modifying Makefile • There are three places in Makefileyou will have to modify • OBJ_CC • NS_TCL_LIB • INCLUDE • Suppose your new module are • Stored in files myfile.h, myfile.cc, and myfile.tcl • Stored under directory nsallinone-2.35-RC3/ns-2.35/myDir http://www.ns2ultimate.com

  5. 1. C++ Modules • Add “myDir/myfile.o\” to any line following this line OBJ_CC = \ • Note: • The extension must be “.o”, not “.cc” nor “.h” • “.o” is an object file obtained by compiling “.cc” and “.h”

  6. 1. C++ Modules: Example http://www.ns2ultimate.com

  7. 2. Tcl Modules • Add “myDir/myfile.tcl\” to any line following this line NS_TCL_LIB = \

  8. 3. Including Directory (Optional) • Add “-I./myDir\” to any line following this line INCLUDES = \ • This will include myDir into the compiling path. So that you don’t need to type the full path every time.

  9. Final step • Just run “ make ” at the command prompt • Done!!

  10. For more information about NS 2 Please see chapter 2 in this book from Springer T. Issaraiyakul and E. Hossain, “Introduction to Network Simulator NS2”, Springer 2009 http://www.ns2ultimate.com
