我在使用ns2，我想写一个实现无线传感器网络的tcl代码，我在网上冲浪，发现了一个不完整的代码，我对它做了一些修改并运行它，但是终端给出了这样的结果：channel.cc:sendUp - Calc highestAntennaZ_ and distCST_highestAntennaZ_ = 1.5, distCST_ = 550.0SORTING LISTS ...DONE!Segmentation fault (core dumped)
实际上，这是一个项目，所以如果有人能告诉我代码中的错误，或者给我一个实现无线传感器网络的源代码链接，就没关系了。
这是我的密码。提前谢谢你。

最佳答案
分段故障（堆芯转储）$err set rate_必须>=1.0：
30 proc UniformErrorProc {} {
31 puts "dfdfad-----------------------------"
32 set err [new ErrorModel]
33 $err unit pkt
34
35 $err set rate_ 1.0
36
37 return $err
因此，模拟将运行数小时，三个跟踪文件的大小可以达到GB。可以添加一个“停止”：
13 set val(stop) 50000 ;# EDITED time of simulation end
.
.
116 # Telling nodes when the simulation ends
117 for {set i 0} {$i < $val(nn) } { incr i } {
118 $ns at $val(stop) "$node_($i) reset";
119 }
120 $ns at $val(stop).0002 "puts \"NS EXITING...\" ; $ns halt" ;# added
121 $ns at $val(stop).0001 "stop" ;# added
122 proc stop {} {
123 global ns tracefd namtrace
124 $ns flush-trace
125 close $tracefd
126 close $namtrace
127 exec nam simwrls & ;# edited
128 }
129
130 $ns run
运行模拟。。。
