我找不到解决这个问题的方法,当我改变时
for {set i 0} {$i < $opt(row)} {incr i} {
for {set j 0} {$j < $opt(col)} {incr j} {
到
for {set i 1} {$i < $opt(row)} {incr i} {
for {set j 1} {$j < $opt(col)} {incr j} {
我发现另一个问题是&#34;无法读取&#34; node_(0)&#34;:没有这样的变量
set opt(netif) Phy/WirlessPhy ;#network interface type
set opt(chan) Channel/WirelessChannel ;#channel type
set opt(prop) Propagation/TwoRayGround ;#radio-propagation model

&#34;无法读取&#34; node_(0)&#34;:没有这样的变量
没有定义节点:文件中缺少用于节点配置的行。
&#34;无法阅读&#34; ifqlen _&#34;:没有这样的变量&#34;
由第1行的拼写错误引起:Phy / WirlessPhy→必须是Phy / Wir e lessPhy
当修复~100拼写错误时,你的文件到目前为止工作,创建文件TP2.nam 9.2kB,TP2.tr 5.2kB。文件大小非常小可能是由此错误引起的:--- Classfier::no-slot{} default handler (tcl/lib/ns-lib.tcl) ---
编辑:得到了结果,没有错误:其他节点位置→跟踪文件现在是24MB / 13MB。
$node_(0) set X_ 299
$node_(0) set Y_ 248
$node_(1) set X_ 297
$node_(1) set Y_ 496
$ nam TP2.nam
:一个OK动画。
编辑过的文件:不完美....但是要处理的事情...... (file.diff:Original vs edited https://www.dropbox.com/s/98wxqbgttyj8arv/Priority-Queue.tar.gz?dl=0)
