You can get these parameters by applying the following awk script on you output
trace file.
The WK script to measure send, receive, routing and drop packets. Packet
delivery ratio, routing overhead, normalize routing load, average end to end
delay.
---------------------------------------------------------------------------------------------
BEGIN { sends=0; recvs=0; routing_packets=0.0;
droppedBytes=0; droppedPackets=0; highest_packet_id =0;
sum=0; recvnum=0; } { time = $3; packet_id = $41; #
CALCULATE PACKET DELIVERY FRACTION if (( $1 == "s") && ( $35 == "cbr" ) && (
$19=="AGT" )) { sends++; } if (( $1 == "r") && ( $35 == "cbr" ) && (
$19=="AGT" )) { recvs++; } # CALCULATE DELAY if (
start_time[packet_id] == 0 ) start_time[packet_id] = time; if (( $1 == "r")
&& ( $35 == "cbr" ) && ( $19=="AGT" )) { end_time[packet_id] = time; }
else { end_time[packet_id] = -1; } # CALCULATE TOTAL DSR OVERHEAD if
(($1 == "s" || $1 == "f") && $19 == "RTR" && $35 =="DSR") routing_packets++;
# DROPPED DSR PACKETS if (( $1 == "d" ) && ( $35 == "cbr" ) && ( $3 > 0
)) {
droppedBytes=droppedBytes+$37;
droppedPackets=droppedPackets+1; } #find the number of packets
in the simulation if (packet_id > highest_packet_id)
highest_packet_id = packet_id; } END { for ( i in end_time ) { start
= start_time[i]; end = end_time[i]; packet_duration = end - start; if (
packet_duration > 0 ) { sum += packet_duration; recvnum++; } }
delay=sum/recvnum; NRL = routing_packets/recvs; #normalized routing
load PDF = (recvs/sends)*100; #packet delivery ratio[fraction]
printf("send = %.2f\n",sends); printf("recv = %.2f\n",recvs);
printf("routingpkts = %.2f\n",routing_packets++); printf("PDF =
%.2f\n",PDF); printf("NRL = %.2f\n",NRL); printf("Average e-e
delay(ms)= %.2f\n",delay*1000); printf("No. of
dropped data (packets) = %d\n",droppedPackets); printf("No. of dropped
data (bytes) = %d\n",droppedBytes);

Hi Mohammed Abu Hajar,
Could you please tell me your awk files to
measure send, receive, routing... that were ran for DSR? can you send me
related trace file?
Thanks so much.
Wei
