[Contiki-developers] Throughput measures

[Melanie Schranz]

Hello everybody!

I want to measure throughput and packet loss between two tmote sky motes. What is the right tool to do so?

Thanks for answers

There are many ways to calculate the throughput. One way to calculate
the end-to-end throughput for node "1" is defined as the rate of the
number of data packets (bits/sec) from node "1" that have arrived at
the base node (nPackets) over the elapsed time since the first packet
from node i has arrived (Duration).

Per-node throughput for node "1" = nPackets(at node "1") *
Packet_size(bits) / Duration (sec)

Its better to consider all the packets, inclusive retransmissions done by MAC.

First define the packet which include the sequence number. you can
program tmote sky (Node "1") which is sending let suppose 1
packet/sec, and other node received (base node) the packets from Node
"1". At receiving node you can compare the current packet sequence
number with the previous packet sequence number to calculate the
packet lost.

hope it will helps.

Hi,
 Aren't there any "standarized tools" for this purpose. Or do we have to develop for ourselves?
 
Best regards,
Qasim.

HI!

I'm very new to cotniki. Are there any specific lines of code in order to get it the way you described?

Thanks in advance
Melanie

    how to find throughput(a send node send how many packets and a sink node how many packets received in a unit time) in a sky mode?
