Set of mechanisms and communication protocols through which several "interlocutors" (devices in a network, such as computers, mobile phones, etc..) agree to share a common transmission medium. This is generally electrical cable or optical fiber, or in wireless communications the frequency range assigned to the system.
The repository is divided in two exercises:
-
finite-user slotted ALOHA protocol.
- Utilize Matlab to analyze the probability of 0,1,..M users in Backlog state.
- Portray each state probabilities and calculate the System average values of Throughput,S, and Delay, D.
- Study of Capture Effect for the system when backlog transmit probability is small (<<1).
-
Analysis of CSMA/CA systems performance in saturation conditions.
- Analyze Giuseppe Bianchi proposal and obtain similar results.
Image below shows exercises 1 and 2 guidelines.
the next image shows some examples of parameters to use for implementing the exercises solutions.
