Subject: [manet] AODV and DSR trace file curiosity

Hi folks,

I noticed a difference in trace files of AODV and DSR.
Somehow AODV generates one line less than AODV for each data packet.

In the following you see snippets from trace files based on simulation runs
with
3 nodes and chain topology: 0 - 1 - 2

Both AODV and DSR generate 2 events at the agent layer.
At the routing layer AODV has 4 events, and DSR 5 events.

AODV:
s -t 3.000000 -Hs  0 -Hd -2 -Ni  0 -Nl AGT -Nw --- -Is   0.0 -Id   2.0 -It
cbr -Il 64 -If 0 -Ii 1 -Iv 32 -Pn 0 -Pi 1 -Pf 0 -Po 0
r -t 3.000000 -Hs  0 -Hd -2 -Ni  0 -Nl RTR -Nw --- -Is   0.0 -Id   2.0 -It
cbr -Il 64 -If 0 -Ii 1 -Iv 32 -Pn 0 -Pi 1 -Pf 0 -Po 0
s -t 3.000000 -Hs  0 -Hd  1 -Ni  0 -Nl RTR -Nw --- -Is   0.0 -Id   2.0 -It
cbr -Il 84 -If 0 -Ii 1 -Iv 30 -Pn 0 -Pi 1 -Pf 0 -Po 0
r -t 3.002106 -Hs  1 -Hd  1 -Ni  1 -Nl RTR -Nw --- -Is   0.0 -Id   2.0 -It
cbr -Il 84 -If 0 -Ii 1 -Iv 30 -Pn 0 -Pi 1 -Pf 1 -Po 0
f -t 3.002106 -Hs  1 -Hd  2 -Ni  1 -Nl RTR -Nw --- -Is   0.0 -Id   2.0 -It
cbr -Il 84 -If 0 -Ii 1 -Iv 29 -Pn 0 -Pi 1 -Pf 1 -Po 0
r -t 3.004396 -Hs  2 -Hd  2 -Ni  2 -Nl AGT -Nw --- -Is   0.0 -Id   2.0 -It
cbr -Il 84 -If 0 -Ii 1 -Iv 29 -Pn 0 -Pi 1 -Pf 2 -Po 0

DSR:
s -t 3.000000 -Hs  0 -Hd -2 -Ni  0 -Nl AGT -Nw --- -Is   0.0 -Id   2.0 -It
cbr -Il  64 -If 0 -Ii 5 -Iv 32 -Pn 0 -Pi 1 -Pf 0 -Po 0
r -t 3.000000 -Hs  0 -Hd -2 -Ni  0 -Nl RTR -Nw --- -Is   0.0 -Id   2.0 -It
cbr -Il  64 -If 0 -Ii 5 -Iv 32 -Pn 0 -Pi 1 -Pf 0 -Po 0
s -t 3.000000 -Hs  0 -Hd  1 -Ni  0 -Nl RTR -Nw --- -Is   0.0 -Id   2.0 -It
cbr -Il 104 -If 0 -Ii 5 -Iv 32 -Pn 0 -Pi 1 -Pf 0 -Po 0
r -t 3.002506 -Hs  1 -Hd  1 -Ni  1 -Nl RTR -Nw --- -Is   0.0 -Id   2.0 -It
cbr -Il 104 -If 0 -Ii 5 -Iv 32 -Pn 0 -Pi 1 -Pf 1 -Po 0
f -t 3.002506 -Hs  1 -Hd  2 -Ni  1 -Nl RTR -Nw --- -Is   0.0 -Id   2.0 -It
cbr -Il 104 -If 0 -Ii 5 -Iv 31 -Pn 0 -Pi 1 -Pf 1 -Po 0
r -t 3.005236 -Hs  2 -Hd  2 -Ni  2 -Nl RTR -Nw --- -Is   0.0 -Id   2.0 -It
cbr -Il 104 -If 0 -Ii 5 -Iv 31 -Pn 0 -Pi 1 -Pf 2 -Po 0
r -t 3.005236 -Hs  2 -Hd  2 -Ni  2 -Nl AGT -Nw --- -Is   0.0 -Id   2.0 -It
cbr -Il  64 -If 0 -Ii 5 -Iv 31 -Pn 0 -Pi 1 -Pf 2 -Po 0

Especially, the last routing layer event of DSR looks somehow curios, or?
On the other hand the you find '-Pf 2' in both routing techniques at the
agent layer, but the packet was forwarded only 1 times, or not?
Does someone has an explanation?
