Hello,
I get this error but I don't know how to solve it. In my script, I
create 2 wired nodes, then 13 wireless nodes, then 2 base stations.
And in NAM I get this message:
Skipping duplicate node 15 definition.
Skipping duplicate node 16 definition.
I turn off adhoc routing in wired nodes, turn wireless routing on for
wireless nodes, then turn on wired routing for BS. Below is a
extraction of my script:
===== BEGIN quote =====
#
#create wired nodes
#
set W(0) [$ns_ node]
set W(1) [$ns_ node]
#$W(0) set X_ 0
#$W(0) set Y_ 900
#$ns_ initial_node_pos $W(0) 30
#$W(1) set X_ 750
#$W(1) set Y_ 750
#$ns_ initial_node_pos $W(1) 30
#
# configure mobile nodes
#
$ns_ node-config -adhocRouting $opt(adhocRouting) \
-llType $opt(ll) \
-macType $opt(mac) \
-ifqType $opt(ifq) \
-ifqLen $opt(ifqlen) \
-antType $opt(ant) \
-propType $opt(prop) \
-phyType $opt(netif) \
-channelType $opt(chan) \
-topoInstance $topo \
-wiredRouting OFF \
-agentTrace ON \
-routerTrace ON \
-macTrace OFF
for {set i 0} {$i < $opt(nn)} {incr i} {
set node_($i) [$ns_ node]
}
# configure for base-station node
$ns_ node-config -wiredRouting ON
for {set i 0} {$i < $opt(bn)} {incr i} {
set BS($i) [$ns_ node]
$BS($i) random-motion 0 ;#<hainam> don't know why, is it enabled by default?
}
$BS(0) set X_ 0
$BS(0) set Y_ 750
$ns_ initial_node_pos $BS(0) 30
$BS(1) set X_ 600
$BS(1) set Y_ 900
$ns_ initial_node_pos $BS(1) 30
===== END quote =====
It's more strange when I comment out those two lines at the end, error
don't exist any longer.
===== BEGIN quote =====
$BS(0) set X_ 0
$BS(0) set Y_ 750
#$ns_ initial_node_pos $BS(0) 30
$BS(1) set X_ 600
$BS(1) set Y_ 900
#$ns_ initial_node_pos $BS(1) 30
===== END quote =====
And in both cases, two wired nodes and two base stations are put at
the same position!
Any suggestions ?
Thanks in advance,
