[ns] weird data after -Hd in the trace file

[<lyang01@fiu.edu>]

Hi, there,

I am having a problem with understanding the trace file of my simulation. My simulation is similar to wireless1.tcl (wired-cum-wireless example). I have one mobile node sending a packet to the basestation and getting the repsonse back. In my trace file, I got the some lines of the following data:

f -t 145.005917116 -Hs 2 -Hd 4194306 -Ni 2 -Nx 1.00 -Ny 2.00 -Nz 0.00 -Ne -1.000000 -Nl RTR -Nw --- -Ma 0 -Md 0 -Ms 0 -Mt 0 -Is 4194304.0 -Id 4194305.0 -It Sdd -Il 84 -If 0 -Ii 54 -Iv 32 

r -t 145.007323461 -Hs 4 -Hd 4194306 -Ni 4 -Nx 221.83 -Ny 80.86 -Nz 0.00 -Ne -1.000000 -Nl RTR -Nw --- -Ma a2 -Md 2 -Ms 0 -Mt 800 -Is 4194304.0 -Id 4194305.0 -It Sdd -Il 84 -If 0 -Ii 54 -Iv 32 

If you notice that the number after -Hd is a very huge one. I know it's supposed to be a node id. And in my simulation I only have 3 mobile nodes, 1 basestation node and 2 wired node. So what's the 4194306  represented? Any idea?

Any information is appreciated.

Thanks.
