问题描述

我正在使用 ns.35 和使用 DSR 执行此代码时在移动 Ad Hoc 网络 (MANET) 中开展一个项目

它显示在 tr 文件中.. 为什么？怎么处理？

Sconfig 0.00000 tap: on snoop: rts?犯错了吗？在 Sconfig 0.00000 打捞：在 !bd 上回复？在 Sconfig 0.00000 grat 错误：在 grat 回复：在 Sconfig 0.00000 $reply for props: on ring 0 search: on 使用 MOBICACHE 配置 0.00000

解决方法

Sconfig 是 DSR 设置。跟踪线表明哪些 Sconfig 处于开启状态。 ... 请参阅 Sconfig.jpg 等跟踪文档 https://drive.google.com/drive/folders/1X_SaZcTYF2tI5XGVClImBvAZY1_QOrDj?usp=sharing

Sconfig.jpg 显示了来自“NS-2 跟踪格式 - nsnam.html”= NS-2_TraceFormats-nsnam.html 的片段

$ cd ns-2.35
$ grep -nR Sconfig *
dsr/dsragent.cc:468:  trace("Sconfig %.5f tap: %s snoop: rts? %s errs? %s",dsr/dsragent.cc:473:  trace("Sconfig %.5f salvage: %s !bd replies? %s",dsr/dsragent.cc:477:  trace("Sconfig %.5f grat error: %s grat reply: %s",dsr/dsragent.cc:481:  trace("Sconfig %.5f $reply for props: %s ring 0 search: %s",dsr/linkcache.cc:309:   trace("Sconfig %.5f using LINKCACHE %d",Scheduler::instance().clock(),dsr/mobicache.cc:209:   trace("Sconfig %.5f using MOBICACHE",Scheduler::instance().clock());
dsr/simplecache.cc:204: trace("Sconfig %.5f using MOBICACHE",Scheduler::instance().clock());

这意味着 grep 已在 ns2、所有目录和所有子目录中搜索单词 Sconfig。

当我使用此代码时 $ cd ns-2.35 $grep -nR Sconfig *. 出现如下：
