For the 3 examples, the instrument I am connecting to is a circuit board with an inclinometer, which can work in the 3 modes I will be describing below. I'll define 3 different cases to illustrate, from the simplest to the most demanding.
#MATLAB PROGRAM FOR STOP AND WAIT PROTOCOL SERIAL#
what other functions your main program (or GUI) will have to do aside from managing the serial port.how the instrument you are communicating with behave.It is important to chose the right communication mode. Matlab supports synchronous and asynchronous communication with a serial port. InputBufferSize = 1000000 % Open serial port fopen (s ) # Chosing your communication mode S = serial ( '/dev/ttyusb0', 'BaudRate' ,rate ) end % Set the input buffer size to 1,000,000 bytes (default: 512 bytes). S = serial ( '/dev/tty.usbserial-A104VFT7', 'BaudRate' ,rate ) elseif isunix You will % have to look at /dev/tty.* to discover the exact signature of your % serial device % Note that on OSX the serial device is uniquely enumerated. S = serial ( 'COM1', 'BaudRate' ,rate ) elseif ismac % Define serial port with a baud rate of 115200 Automatically processing data received from a serial port.Closing a serial port even if lost, deleted or overwritten.Creating a serial port on Mac/Linux/Windows.Ordinary Differential Equations (ODE) Solvers.Fourier Transforms and Inverse Fourier Transforms.IF U R READY TO DO THIS ASSIGNMENT, I CAN PROVIDE U WITH THAT TO HELP U MORE UNDERSTAND WHAT IS NEEDED. I HAVE TWO SAMPLE CODES WITH ME FOR THE SAME ASSIGNMENT.

It is best to accept these values as command line parameters so that it is easy to experiment.ġ) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.Ģ) READ THE INSTRUCTIONS TO SEE WHAT NEEDS TO BE DONE, HOW THE OUTPUT IS TO BE SHOWED Play around with with varying Pt, Rt and P values and see if the results are as expected. This shows what the sends log would like with a data packet is lost and timer expires. If p : įor example, the sender log might look like the following:ġ9:32:32.845455: Sent_packet seqnum=0 Retransmit Generate a random float point number p, between 0 and 1. **How to drop/ignore packet with probability P ?** Just before the receiver sends an ack (after updating variables): Don't send the ack with probability P = 0.2.
#MATLAB PROGRAM FOR STOP AND WAIT PROTOCOL UPDATE#
As soon as the receives gets a packet (before any update to variables): Ignore the packet with probability P = 0.2. At the receiver, write additional code in two placesġ. We need to simulate losses since our network will almost never lose packet. Sender sends data every Pt = 500ms and always has data to send. You will need to modify the meaning of functions in Fig. We will simulate the physical layer by the transport layer using the programs described in the lectureįor the programs on the data link layer follow the Fig. The goal is to implement a data transmission programs that involve two layers:

**General rules: source code must be commented and a description how to run the programs must be attached.** Implement the simplex protocol for a noisy channel (Fig.
