• PDF:

PDF is the ratio of the number of data packets successfully delivered to the destinations to those generated NS2 Simulator Free Download by CBR sources.

Sample code for calculating PDF:

if (( $1 == “s”) && ( $35 == “cbr” ) && ( $19==”AGT” )) { sends++; }

if (( $1 == “r”) && ( $35 == “cbr” ) && ( $19==”AGT” )) { recvs++; }

• Delay:

It is the difference between the packets received time and packet sent time.

Sample code for evaluating 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; }

• Routing Overhead:

Refers to the time it takes to transmit data on a packet switched wireless network.

Sample code predicting routing overhead:

if (($1 == "s" || $1 == "f") && $19 == "RTR" && $35 =="RP") routing_packets++;
