Installing tcp-westwood

1. Add the modules tcp-westwood.cc and tcp-westwood.h to the main NS-2 directory (which is something like: ../ns-allinone-2.28/ns-2.28 /tcp

2. Modify the Makefile so that it compiles and links the new module (i.e. add tcp/tcp-westwood.o anywhere in the OBJ_CC variable, for example near the other TCP related modules like tcp-newreno.o or tcp-vegas.o). You can find the Makefile under the main NS-2 directory

3. Add the following lines at the end of ns-default.tcl (it can be found in the tcl/lib directory under the main NS-2 directory):

Agent/TCP/Westwood set current_bwe_ 0
Agent/TCP/Westwood set last_bwe_sample_ 0
