transport-layer-tcp-protocol

Transport layer TCP-protocol template in which the corrupted blocks are identified and resent to the transmitter. Used with QRadioLink or GNU Radio to effeciently communicate via radio transmitters.

./install.sh

Usage

./pack.pl file > transmit-file

file is an original file that is to be obtained by the receiver.
transmit-file is a file that is transmitted via QRadioLink or GNU Radio to attain such obtaining.

transmit-file must be stored untill the radio transmission is succesfully completed.

./unpack.pl received-file

received-file is a file where the data received by QRadioLink or GNU Radio is stored.

If the transmission was succesfull, the received-file is identical to transmit-file.
In such case, unpack.pl will decode the received-file.
In other case, unpack.pl will report on damaged blocks and create a confimed.txt file.
confirmed.txt should be obtained by the transmitter, e.g. via Telegram =)

./unpack_tcp.pl

Identical to the latter command, except this one listens 127.0.0.1:20000 infinitely and stores each received-file in received-files direcory.

Can process multiple files with different names concurrently.
GNU Radio should be configured as a client sending data to 127.0.0.1:20000.

./resend.pl transmit-file confirmed-file > resend-file

transmit-file and confirmed-file are as stated above.
resend-file is a file consisting of blocks that are to be resended to the receiver untill the received-file is identical to the resend-file
