[ns] something wrong

[Liang Qin <lqin@sce.carleton.ca>]

Hi Jeffrey,

This morning I run the nam for the trace file (which I think ) has problem.
Here is one example:

-----------------
r 507.095840558 _11_ RTR  --- 17826 cbr 64 [0 0 0 0] ------- [11:0 12:0 32 0] [1554] 0 4
s 507.095840558 _11_ RTR  --- 17826 cbr 92 [0 0 0 0] ------- [11:0 12:0 32 12] [1554] 0 4
r 507.096906713 _12_ RTR  --- 17826 cbr 92 [a2 c b 800] ------- [11:0 12:0 32 12] [1554] 1 4
r 507.096906713 _12_ AGT  --- 17826 cbr 92 [a2 c b 800] ------- [11:0 12:0 32 12] [1554] 1 4
-----------------

I can see from nam, actually node 11 and node 12 are far apart. but in
simulation they are just in one hop. 

Also I run some simulation using ns2's scenario files for 50 nodes, no packet's
actual hop count less than optimal hop count for DSDV, DSR and AODV. 

There must be somthing wrong here.
