I'm using ns-2.28 for the simulation of Mobile IP.
I set the positions of MN(MobileNode), HA(HomeAgent), FA1(ForeignAgent), FA2
are (10,10), (10,10), (800,20), (800,800). And the topo that I set is
1000*1000. When the ns run, the positions of HA and FA are not what I set in
NAM.However the MN's position is correct.
I'd appreciate any help and any pointer to how I can find & fix this problem.
The TCL scpirt as follow:
