Incorporating Leach
I thought about using the older version of ns2, but figured that it should be too hard to compile leach with the new version. Besides, there are probably bug fixes that I would want to keep up with. ns2 should have an easier way to incorporate new protocol, instead of modifying existing code.
ns-2.1b5 is the last build LEACH was written for. The directory structure of ns-2.1b5 is different from ns-2.27, and thus, some of the files go into different directories now. Assuming a directory of ns2.27, The following files from the ns-2.27 will change with the LEACH protocol:
These files are unchanged, even though they're included in the MIT_uAMPs distribution. I found that it was unnecessary to incorporate these changes, because those changes had been accepted in ns2.27:
The are new files that you will need to add. I put them in the /mac subdirectory
Instead of just copying the old files, I searched for
to see where it is the leach made changes, and made the corresponding changes in the existing ns2.27 code. I will post the new ns2.27 modified LEACH code later.
The Makefile.in also changes. I have added the following definitions:
I added $(INCLUDES_MIT) to the end of the definition of $(INCLUDES)
I also added $(OBJ_MIT:.o=.c) to the end of the following:
And added $(OBJ_MIT) to the end of the following:
