Simulation of Slotted ALOHA in MATLAB

Slotted-Aloha has to employ various kinds of control algorithm to ensure the system stability.Before an algorithm is applied in practice,a simulation test must be conducted to test its reliability.Based on the comparison of the three commonly used network simulation tools,principles of discrete event MATLAB simulation and the principles of random number generation based on Monte Carlo Method is subjected to analysis.The control algorithm flowchart of slotted ALOHA on MATLAB is presented,on the basis of which MATLAB code is written and then a simulation test is done to the Performance of Pseudo Bayesian control algorithm and the results show that MATLAB can well fulfill the simulation of the slotted ALOHA algorithm.
