Question

Given the file messages.dat [ https://drive.google.com/open?id=1V4uRvNoqwsxpVKAlvdvIlX-3XqxFMXHn ]that consists of four columns:

message number | payload bits | jitter | deadline/period

Using the MATLAB ‘load’ command, this file can be turned into a MATLAB matrix whose columns correspond to the file columns.

Perform the following tasks:

1) Write a MATLAB function that computes and returns the required bits/message and number of bits/second for each of the messages in the file. In this case you can have the function return a new matrix with two new columns.

Bits/message = [(54 +8*Sm)/4]+67+8*Sm,

Where Sm = “payload bits”/8   (round up to magnitude of two numbers: 1, 2, 4, 8, 16… and so on)

Bits/second = Bits/message * [1000/“deadline/period”]

2) Write a MATLAB function that ranks the messages in the file by priority (highest priority first) using deadline monotonic scheduling. In this case you can have the function return a new matrix whose rows have changed location based on priority.

[“deadline monotonic scheduling” means: order the items with respect to the “deadline/period” column. Shortest to the longest time]
