Hi all !,
I have ns-2 2.30 and I've installed recently NOAH protocol. After succesful
test in wireless simple scenario, I add a couple of wired nodes, resulting a
topology of two wired nodes, one base station node, and 4 wireless nodes (one
of them acts as a repeater that connects the rest of the wireless nodes and
base-station node). Problem comes when I send traffic form a wired node to a
wireless one, appearing this error:
--- Classfier::no-slot{} default handler (tcl/lib/ns-lib.tcl) ---
_o18: no target for slot -1
_o18 type: Classifier/Hash/Dest
content dump:
classifier _o18
0 offset
0 shift
2147483647 mask
1 slots
slot 1: _o152 (Classifier/Port)
-1 default
---------- Finished standard no-slot{} default handler ----------
I am using cygwin in its latest release, but I think there is no problem
with that. If anyone could help me, I ould be very pleased. Thanks in advance!!
I enclose my whole script, if it helps:
