Hi, I can tell another way which I think is simpler to do this clone stuff, for your reference only. You can directly change the AODV codes in the ns/aodv/ directory without change the name of the directory and files (of course you'd better backup the oringal codes first), and rebuild the codes. This approach would cause less problems related to the makefile and ns-lib.tcl kind of things, so maybe worth a shot. good luck Larry
Hello, NS-users: I want to create a routing protocol according to AODV, so my first task is to clone AODV. After seeing other ns-users' posts, i do my work in following steps. First, i copy all the files in $NS\aodv\ to a new folder called aodv_lsa and rename all files (i.e. from filename.cc and filename.h to myfilename.cc and myfilename.h), and then i change all the names of C++ classes, packet headers, variables, TCL bindings, ... Second, i make some essential changes according to http://masimum.dif.um.es/nsrt-howto/html/ $NS\common\packet.h enum packet_t { PT_TCP, PT_UDP, PT_CBR, ...... ...... PT_AODV, PT_MYAODV, //added by Xinhao Yu PT_IMEP, ...... ......

After 'make depend', there is no error. Then 'make' and everything is ok. Then i use a simple tcl script to test my new ns model. I replace AODV with MYAODV. set val(rp) MYAODV ;# Routing: MYAODV Tcl script runs fine. I get a trace file.

Could anyone explain to me what's the matter? Thank you in advance. -- Best Regards, Xinhao Yu
