hi I want to do routing ad hoc simulation, the network is composed by end node and transit-node when the end-node can't transmis a demand to the transit node if he (end-node) is not the source and the transit node can't transmis the demand to the end-node if he is not destination, so i dont know how i will add the new characteristic for the specific node (end-node and transit node) and the classes necessary for routing path with this, what i must do in this classes. thank you
