Before calculating the Packet Delivery Ratio we need the following parameters
- Time (PHY_LAYER_END_TIME) (µS)
- Total Packet Transmitted
- Total Packet Transmitted successfully
Steps to tabulate the above parameters
Step 1: Make sure that the Packet-Trace is enabled before running the simulation.
Step 2: After the simulation in Metrics window open Packet Trace.
Step 3: Filter the Source ID and Destination ID to calculate the delivery ratio.
Step 4: Copy PHY_LAYER_END_TIME(µS) and Packet Status of all rows to SHEET 2.
Step 5: In addition to the above two columns add three more column "Packets Transmitted", "Packet Transmitted Successfully", "Packet Delivery Ratio"
Step 6: For Packets Transmitted give numbering from 1-n packets
Step 7: For Packet transmitted Successfully, select the respective cell to the 1st packet and write the formula as "=IF(B2="Successful",COUNTIF($B$2:$B2,"Successful"),COUNTIF($B1:$B$2,"Successful")) "
Step 8: For Packet Delivery Ratio, select the respective cell to the first packet and write the formula as "=D:D/C:C"
Step 9: Filter only Successful packets and plot the graph with respect to time
