networking - how can you count the number of packet losses in a file transfer? -


one of networks course projects has 802.11 protocol.

me , parther thought exploring "hidden terminal" problem, simulating it.

we've set private network. have 2 wireless terminals attempt send file 3rd terminal connected router via ethernet. rts/cts disabled.

to compare results, we'd measure number of packet collisions occured during transfer conclude due rts being disabled.

we've read imposible measure packet collisions noise. we'll have make counting packets didnt recieve "ack". basically, number of retransmitions. how can that?

i suggested instead of sending file, make 2 wireless terminals ping 3rd terminal continually. ping feature automatically counts ping packets didnt recieve "pong". think viable approach?

thank much.

no, you'll incorrect results. ping application, i.e. working @ application (highest) level of network. 802.11 protocol operates @ mac layer - there @ least 2 layers separating between ping , 802.11. whatever retransmissions happen @ mac layer - hidden layers above it. you'll see failure in ping if retransmissions initiated lower levels have failed.

you need work on same level you're investigating - in case it's mac layer. can use sniffer (google it) statistics want.
