The code is self explanatory, but for the sake of clarity it is

elaborated in this section. The code requires a set of input

values for the parameters, for example, the value of “threshold signal”, which is

the value of signal strength. Any signal having strength less than this threshold value is

considered weak and any signal having strength greater than the threshold value is

considered as strong. We can also choose to set the user in any of the networks at the start of

the simulation. Obviously in real world whether the user is working in a network is

determined by the position of the user or the position of his device to be more precise. Also

simulation is carried on for a specific period of time. For speeding up the simulation process,

time has been converted to number of iterations. At the start of any iteration the signal

strength is measured.
