Hi, 
there is a unique node ID generated by NS2 for the nodes during their creation. 
it's an int. and since  a short int is 16 bits, an int is 32 bits, and a long 
int is 64 bits. i suppose by acceding the class Node in the c++ hierarchy and 
setting the "int nodeid_" member as "short int nodeid_", you will get what u 
want (NS2 will generate the id as short int (16 bits)). of course you have to 
recompile...
