Please let me know how to get the following network metrics for wireless communication analysis from generated results and from packet/event trace
- Routing Overhead
- Network Lifetime
- Signal to Noise Ratio
- Hop Count
- Bandwidth
- Data Rate
Parameters such as total routing packets sent, total data packets received etc, can be obtained from NetSim Packet Trace file.
Routing Overhead can be calculated by dividing the total number of routing packets sent by the total number of data packets received.
To obtain the total routing packets that were sent including those that were forwarded, filter only DSR protocol related packets from CONTROL_PACKET_TYPE/APP_NAME column.
To obtain the total data packets received, in the packet trace filter only CUSTOM packets from the column PACKET_TYPE.
Hello Raid, I am using NetSim v10.2 (https://www.tetcos.com)
Thank you Sai. I understood how to get Routing Overhead. Can you guide me on the other metrics I had asked also? Thank you
Hop count can conveniently be obtained from the packet trace file.
You can run a WSN simulation with packet trace enabled. Then open the packet trace and use the Excel filter from the menu. Filter and select any one Packet_ID.
This will show you the flow of packets from the source till the destionation and that would give you the hope count as well.
Network Lifetime -- See the remaining energy in the sensors in the results window of NetSim. Depending on your definition you could say the time that the first sensor reaches zero remaining energy or say 1/2 the sensors reach zero remaining energy
Getting the SNR will involve writing some code and you can see the link https://tetcos.freshdesk.com/support/solutions/articles/14000081750-how-to-obtain-a-log-of-rssi-sinr-and-ber-in-802-15-4-
