awk script for nrl

[umair ahmed]

Hi this my awk script which i use for normalized routing load ,it works fine but i have one question what is the difference between normalized routing load and routing overhead and the other question is in comments of awk file #AWK program to calculate Normalised Routing Load of AODV in new trace format. Normalised Routing Load is the number of routing packets per data packets delivered at the destination. $35 also includes message{don't know why } BEGIN { recvs =0; routing_packets =0; } {  if (( $1 == "r") &&  ( $35=="cbr" ) && ( $19=="AGT" )) recvs++; if (($1 == "s" || $1 == "f") && $19 == "RTR" && ( $35 =="AODV" || $35 =="message" || $35 =="DSR"|| $35 =="OLSR")) routing_packets++; } END{ printf("NRL = %.3f\n", routing_packets/recvs); }
