You can start off with Greis's tutorial on creating a new protocol for ns.
http://www.isi.edu/nsnam/ns/tutorial/
Read ns-manual chapter on unicast routing. see LS examples and test
scripts under tcl/ex and tcl/test.

LS is mostly implemented under ~ns/linkstate/* and
tcl/rtglib/rtProtoLS.tcl
There maybe some other files to look at as well.

current LS in ns is implemented in C++ with Otcl interfaces.
If your experiment required it, you could change that.
