OLSR implementation in NS2
 
Hi while running the .awk script to find out the end to end delay, jitter, throughput. I am getting the the following error line 44 " Fatal error: division by zero attempted". I am using the following script

BEGIN {
seqno = -1;
droppedPackets = 0;
receivedPackets = 0;
count = 0;
}

{

#packet delivery ratio
if($19 == "AGT" && $1 == "s" && seqno < $47) {
seqno = $47;
} else if(($19 == "AGT") && ($1 == "r")) {
receivedPackets++;
} else if ($1 == "d" && $35 == "tcp" && ($21 == "CBK" || $21 == "NRTE")){
droppedPackets++;
}
#end-to-end delay
if($19 == "AGT" && $1 == "s") {
start_time[$47] = $3;
} else if(($35 == "tcp") && ($1 == "r")) {
end_time[$47] = $3;
} else if($1 == "d" && $35 == "tcp") {
end_time[$47] = -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";
}

OLSR
 
u can use Ns Analyser to generate the graph, it is much easier, by the way, can u teach me how u patch the OLSR protocol successfully?
