[ndnSIM] AWK in ns3 (ndnSIM)

[Farwa A. Hannan]

Hi,

I am using *AWK script* for calculating *delays and retransmissions*.
Following the the script which I'm using in *"Delay-Retrans-3.awk"*.


# AWK Script
BEGIN {
total_delayus=0;
last_seq_number;
num_of_values=0;
avg_retrans=0;
sum_retrans=0;
total_delayus2=0;
last_seq_number2;
num_of_values2=0;
avg_retrans2=0;
sum_retrans2=0;
total_delayus3=0;
last_seq_number3;
num_of_values3=0;
avg_retrans3=0;
sum_retrans3=0;
{
}
if (( $2 == "0" ) && ( $5 == "FullDelay" )) {
total_delayus = total_delayus + $6;
last_seq_number = $4;
sum_retrans = sum_retrans + $8;
num_of_values = num_of_values + 1;
}
if (( $2 == "7" ) && ( $5 == "FullDelay" )) {
total_delayus2 = total_delayus2 + $6;
last_seq_number2 = $4;
sum_retrans2 = sum_retrans2 + $8;
num_of_values2 = num_of_values2 + 1;
}
if (( $2 == "9" ) && ( $5 == "FullDelay" )) {
total_delayus3 = total_delayus3 + $6;
last_seq_number3 = $4;
sum_retrans3 = sum_retrans3 + $8;
num_of_values3 = num_of_values3 + 1;
}
}
END {
avg_retrans = sum_retrans / num_of_values;
avg_retrans2 = sum_retrans2 / num_of_values2;
avg_retrans3 = sum_retrans3 / num_of_values3;
#printf("Total_Delay_: %.4f Avg_of_ReTX_: %.3f\n",
1total_delayus, avg_retrans );
#printf("Total_Delay_: %.4f Avg_of_ReTX_: %.3f\n",
total_delayus2, avg_retrans2 );
printf("1pair Total_Delay_: %.4f Last_Seq_Number_: %d
Avg_of_ReTX_: %.3f\n", total_delayus, last_seq_number,
avg_retrans );
printf("2pair Total_Delay_: %.4f Last_Seq_Number_: %d
Avg_of_ReTX_: %.3f\n", total_delayus2, last_seq_number2,
avg_retrans2 );
printf("3pair Total_Delay_: %.4f Last_Seq_Number_: %d
Avg_of_ReTX_: %.3f\n", total_delayus3, last_seq_number3,
avg_retrans3 );
}


I am running it on the terminal using the following command

awk -f Delay-Retrans-3.awk "./app-delays-trace.txt"


For all of this I am using ns3(ndnSim). But instead of getting the output
I'm getting the following error messages

awk: Delay-Retrans-3.awk:44: 1total_delayus, avg_retrans );
awk: Delay-Retrans-3.awk:44:               ^ syntax error
awk: Delay-Retrans-3.awk:46: total_delayus2, avg_retrans2 );
awk: Delay-Retrans-3.awk:46:               ^ syntax error
awk: Delay-Retrans-3.awk:47: printf("1pair Total_Delay_: %.4f
Last_Seq_Number_: %d
awk: Delay-Retrans-3.awk:47:        ^ unterminated string
awk: Delay-Retrans-3.awk:47: printf("1pair Total_Delay_: %.4f
Last_Seq_Number_: %d
awk: Delay-Retrans-3.awk:47:        ^ syntax error

Please guide me to solve the problems. Since I'm unable to solve it.
Thanks
