Well i did this...but i dont know if it's ideal...i think it would work though....
I synchronized the two computers to a server on the internet before every capture so both have the exact same time. i have my sniffer in the two computers, the one that sends and the ones that receive. I created a function in matlab that calculates the difference between those two times... I am being really carefull when i have a packet lost or things like that.... But probably this can work???? ...
