hi all,
recently I use aodv+802.15.4 ,after I finish my own project ,and I looked original source code and experimental results of aodv and I find I could not understand the results and do not know the reason,here is the part of trace file
I use wpan_demo1.tcl and aodv

before 0.20000  source node found the path to the destination node and the path is 19-> 20->21->24->6
and then node 19 send its packet to 6,forward to 20 ,and then 21,and 24 and 6
my confusion is why the time suddently to 0.20000?

and then I replace the script with my own,

it is still find the path to the destination ,why stop?
and then skip to the time 2.00000  and have another route request?
