 Hello! ns-users,

  I am working on delay tolerent network(DTN) in ns2. i want to
 implement tcp and udp convergence layer in ns2 for dtn netwotk.so
 convergence layer convert packets(segments) from transport layer to
 appropriate bundle for bundle protocol. please send me the code for
 convergence layer in ns2 also tcl file.
 
 Please help me.
 
 
 Thanking You.

 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.
