You will have to create a new subclass of class "Agent" that contains the code 
of your protocol. You also have to derive from TclClass and register the 
protocol name as well as a routine that makes if possible for the simulator to 
instantiate your protocol whenever the user installs an agent of your customs 
protocol on some node.
You will need C++ to do all this. You probably can use your C-code, though, 
and just adapt it a little. Essentially, you must convert all your functions 
to class member functions and all your global variables and typedefs to class 
variables.

Have a look at some existing agent implementation; a simple example would be 
udp.h and udp.cc.

  Good luck
