Tutorial on modeling and performance analysis of Slotted ALOHA protocol. The source code contains numerical calculation for different models.

• SlottedAlohaTutorial.pdf - tutorial slides
• basic.py Basic model: no retransmission, poisson arrival rate. Plots throughput, collisions and idle slots
• mchain.py Markov chain model, with retransmission probability as a parameter.
• stability.py Additions for markov chain model, plots backlog and throughput and illustrates stability concerns

Models and notations according to: Bertsekas, Dimitri, and Robert Gallager. "Data networks", 1987
