Chapter 4: Functions
A number of functions are used in this code, apart from the built in GUI functions,
bellow is a brief description of these functions.
rej = rejected(num)
This function chooses the appropriate image from the image library to display in the
simulation pane. The input argument num shows the number of current nodes and the
respective image is returned in rej.simu and the status ‘Active devices in PAN’ is
returned in rej.stat, since rej is a structure with fields simu and stat.
im = queue(num,node)
This function loads a queue of images from the image library to show in the simulation
panel after a random delay to show the data sent to each slave according to its time
slot. The variable im is a structure array with fields simu and stat. The size of im
varies with num. The node variable is passed to the function to send the name
information to update the status window.
broad = broadcast(num,node)
The above function is used to update the broadcast image and the status bar according
to the number of nodes present in the network. The structure array node is passed to
this function to get the list of the names, the Master node sends data to. The returned
variable broad has one entry with fields simu and stat.
s = sel(num,node,set_val)
For sending data to a selected user, the above function is used. It gets the variables
num and node to get the names and number of nodes in the network. The third input
argument set_val is used to indicate which client is selected. This is required to load
the proper image and status. It also has the fields simu and stat.
[t t2] = terminating(num1,clone,set_val);
This function is used to represent the terminating figure sequence according to the
number of nodes in the network. set_val is again passed to indicate which device is
being terminated. The variable clone is actually a copy of the structure node just to
save the device info after it is terminated from the network to update the status.
