如何使用Visual Trace Analyzer分析由ns2生成的跟蹤文件？

Question

當我在NS-Visual-Trace-Analyzer中打開一個.tr文件時，它顯示所有的統計數據和圖形結果。但是，當我將能量模型添加到同一網絡的節點時，Visual-Trace-Analyzer顯示沒有發送或接收數據包（沒有任何事件）。

這是Tcl腳本來我努力..

EnergyModel：可能是‘NS-視覺，跟蹤分析儀’是由大量混淆的更多信息跟蹤文件。或者它不是要處理來自「EnergyModel」軌跡的複雜輸出。 NAM在兩種情況下表現出平等的傳播。也可以使用通常的awk和perl腳本進行分析。例如， 「數據包到達時間」 ....（1912線）

$ awk -f tess-Packets.awk twonodes.tr

這發生在我身上過了，我的能量值的禁止印刷解決它從C++到主要跟蹤文件。相反，我在cmu-trace.cc

if (thisnode) { 
     if (thisnode->energy_model()) { 
      // log detailed energy consumption 
      // total energy and breakdown in idle, sleep, transmit and receive modes 
      sprintf(pt_->buffer() + offset, 
       "[energy %f ei %.3f es %.3f et %.3f er %.3f] ", 
       thisnode->energy_model()->energy(), 
       thisnode->energy_model()->ei(), 
       thisnode->energy_model()->es(),    
       thisnode->energy_model()->et(), 
       thisnode->energy_model()->er());     
     } 
     } 

禁用sprintf函數打印能量值，以一個單獨的跟蹤文件

。
