Question

运行以下代码时

：

set ns_     [new Simulator]
set tracefd     [open simple.tr w]
$ns_ trace-all $tracefd

set topo       [new Topography]

$topo load_flatgrid 500 500

create-god $val(nn)

       $ns_ node-config -adhocRouting $val(rp) \
             -llType $val(ll) \
             -macType $val(mac) \
             -ifqType $val(ifq) \
             -ifqLen $val(ifqlen) \
             -antType $val(ant) \
             -propType $val(prop) \
             -phyType $val(netif) \
             -channelType $val(chan) \
             -topoInstance $topo \
             -agentTrace ON \
             -routerTrace ON \
             -macTrace OFF \
             -movementTrace OFF         

    for {set i 0} {$i < $val(nn) } {incr i} {
        set node_($i) [$ns_ node]   
        $node_($i) random-motion 0      ;# disable random motion
    }

$node_(0) set X_ 5.0
$node_(0) set Y_ 2.0
$node_(0) set Z_ 0.0

$node_(1) set X_ 390.0
$node_(1) set Y_ 385.0
$node_(1) set Z_ 0.0

$ns_ at 50.0 "$node_(1) setdest 25.0 20.0 15.0"
$ns_ at 10.0 "$node_(0) setdest 20.0 18.0 1.0"

$ns_ at 100.0 "$node_(1) setdest 490.0 480.0 15.0" 

set tcp [new Agent/TCP]
$tcp set class_ 2
set sink [new Agent/TCPSink]
$ns_ attach-agent $node_(0) $tcp
$ns_ attach-agent $node_(1) $sink
$ns_ connect $tcp $sink
set ftp [new Application/FTP]
$ftp attach-agent $tcp
$ns_ at 10.0 "$ftp start" 

for {set i 0} {$i < $val(nn) } {incr i} {
    $ns_ at 150.0 "$node_($i) reset";
}
$ns_ at 150.0 "stop"
$ns_ at 150.01 "puts \"NS EXITING...\" ; $ns_ halt"
proc stop {} {
    global ns_ tracefd
    $ns_ flush-trace
    close $tracefd
}

puts "Starting Simulation..."
$ns_ run

它给了我以下警告信息： num_nodes设置为2 警告：请使用-channel，如tcl / ex / wireless-mitf.tcl所示初始化列表xListHead 开始模拟...... channel.cc:sendUp - Calc highestAntennaZ_和distCST_ highestAntennaZ_ = 1.5，distCST_ = 550.0 SORTING LISTS ...完成！ NS退出......

在NS2上运行模拟时出现警告消息
