As I understand, the propogation model (freespace, tworayground, shadow) is added at the node characteristics. However, I believe that it is a link property and not a node property.
For a WPAN scenerio, if I want to simulate that there is "freespace" between node A and B and a wall "Shadow model" between node B and C and A wants to send a packet to C through B, how should I define the propogation model for node characteristics of B? Thank you. -Ravit
