NS2 AWK腳本繪製圖形

如何修改代碼以便按行和列列出所有值？NS2 AWK腳本繪製圖形

現在，下面的代碼直接引導我到計算的答案。

例如;

**GeneratedPackets = 2438 
ReceivedPackets = 2386 
Packet Delivery Ratio = 97.8671 
Total Dropped Packets = 9 
Average End-to-End Delay = 31.013 ms**

不過，我想這樣的事情，爲了繪製圖表中的數據：

1 X1 Y1

2 X2 Y2

3 X3 Y3

我曾嘗試方法就像使用這樣的命令： awk -f [scriptname] .awk [tracefilename] .tr> graph.xgr

但它只顯示上面的計算。

BEGIN { 
seqno = -1; 
droppedPackets = 0; 
receivedPackets = 0; 
count = 0; 
} 
{ 
#packet delivery ratio 
if($4 == "AGT" && $1 == "s" && seqno < $6) { 
seqno = $6; 
} else if(($4 == "AGT") && ($1 == "r")) { 
receivedPackets++; 
} else if ($1 == "D" && $7 == "tcp" && $8 > 512){ 
droppedPackets++; 
} 
#end-to-end delay 
if($4 == "AGT" && $1 == "s") { 
start_time[$6] = $2; 
} else if(($7 == "tcp") && ($1 == "r")) { 
end_time[$6] = $2; 
} else if($1 == "D" && $7 == "tcp") { 
end_time[$6] = -1; 
} 
} 
END { 
for(i=0; i<=seqno; i++) { 
if(end_time[i] > 0) { 
delay[i] = end_time[i] - start_time[i]; 
count++; 
} 
else 
{ 
delay[i] = -1; 
} 
} 
for(i=0; i<count; i++) { 
if(delay[i] > 0) { 
n_to_n_delay = n_to_n_delay + delay[i]; 
} 
} 
n_to_n_delay = n_to_n_delay/count; 
print "\n"; 
print "GeneratedPackets = " seqno+1; 
print "ReceivedPackets = " receivedPackets; 
print "Packet Delivery Ratio = " receivedPackets/(seqno+1)*100 
"%"; 
print "Total Dropped Packets = " droppedPackets; 
print "Average End-to-End Delay = " n_to_n_delay * 1000 " ms"; 
print "\n"; 
}

嘗試重新陳述您的問題。包含一個ns2跟蹤輸入，您可以在其中定義要跟蹤的ns2跟蹤文件的哪些元素以獲得所需的輸出。你所包含的awk腳本看起來與繪圖完全不相關。 – n0741337

-2

所有你的代碼的問題先......它將被0給出錯誤最有可能分裂.....通過把一個if(count)修復它只是計數分之前。第二次使用for循環以矩陣格式打印它
