direction of nodes in ns2 in urban

hi guys
i tried to write if statements to find the directions of nodes from source node in urban when the angle degree between them 90 in moving or in corner(coordinate x,y) ?how can write it in aodv.cc file?

thanks..

ns2 documentation http://www.isi.edu/nsnam/ns/doc/index.html

angle : cd ns-2.35/ && grep -Rin angle *
And also : grep -Rin degree *

... to find that those terms are not much used in protocols (like aodv.)
But mostly found in the documentation and in tcl files.

Urban protocols ...

Protocols dealing with GSR (Geographic Source Routing) like OLSR:

Code:

$ grep -Rin degree *

OLSR.cc:736:                                                    if (degree(nb_tuple) > degree(max)) {
OLSR.cc:1973:/// \param tuple the neighbor tuple which has the main address of the node we are going to calculate its degree to.
OLSR.cc:1974:/// \return the degree of the node.
OLSR.cc:1977:OLSR::degree(OLSR_nb_tuple* tuple) {
OLSR.cc:1978:   int degree = 0;
OLSR.cc:1985:                           degree++;
OLSR.cc:1988:   return degree;
OLSR.h:437:     int             degree(OLSR_nb_tuple*);
