NS2:接收的数据包为零

我不知道为什么，但我的节点在ns2中什么也没有收到！ 为什么会发生这种情况？ 代码很好，这是一个很长的程序，我会张贴所有的代码，希望有人能帮助我，这是2个星期，我的工作没有任何改善。。。 有人遇到同样的问题来帮我吗

如果你知道问题出在哪里，请告诉我 谢谢

我已经删除了这些代码（从“交通”部分），它可以工作，但不是我想要的工作：

for {set k 20} {$k < $val(nn) } {incr k} {
set tcp($k) [new Agent/TCP]
set sink($k) [new Agent/TCPSink]
$ns_ attach-agent $node_($k) $tcp($k)
$ns_ attach-agent $node_([expr $val(nn)-$k-1 ]) $sink($k)
#$ns_ connect $tcp($k) $sink($k)


set ftp_($k) [new Application/FTP]
$ftp_($k) attach-agent $tcp($k)
$ftp_($k) set packetSize_ 1024

#$ns_ at [expr rand()] "$ftp_($k) start"
$ns_ at  1.0    "$ftp_($k) start"
$ns_ at $val(stop) "$ftp_($k) stop"
}

对于{set k 20}{$k<$val（nn）}{incr k}{
设置tcp（$k）[新代理/tcp]
设置接收器（$k）[新代理/TCPSink]
$ns_uu附加代理$node_uk（$tcp（$k）
$ns_uu附加代理$node_uu（[expr$val（nn）-$k-1]）$sink（$k）
#$ns_uu连接$tcp（$k）$sink（$k）
设置ftp_uk（$k）[新应用程序/ftp]
$ftp_uk（$k）附加代理$tcp（$k）
$ftp_uk（$k）套装包装尺寸_u1024
#$ns_u位于[expr rand（）]“$ftp_k（$k）开始”
$ns_uu1.0“$ftp_uk（$k）开始”
$ns_uu在$val处（停止）“$ftp_uk停止”
}

请编辑您的问题，将“脚本顶部部分”和设置等包含在内……我这样做了，谢谢您的提醒：）我认为仍然不完整<代码>$ns 2_um-karim-aodv.tcl→ → <代码>无法读取“val（tcpagent）”：数组中没有此类元素。。。。从“交通”。。。。。文件：已编辑，但仍然存在问题提醒，您可以在NS2中运行它吗？
