MATLAB Implementation of Markov Fluid Queues Based Analytical Model for Age of Information in Per-Source Queueing

The script "numericalExample.m" obtains per-source average AoI and per-source age violation probabilities for First Source First Serve (FSFS), Earliest Served First Serve (ESFS) and Single Buffer with Replacement (SBR) policies using an analytical model based on Markov Fluid Queues (MFQ). It is also possible to obtain the exact per-source CDF using this script. To do so, only the inputs of used MATLAB functions in this script should be modified appropriately.The functions "FSFS.m", "ESFS.m" and "SBR.m" construct the MFQ models for the policies FSFS, ESFS and SBR, respectively. Using the MFQ models, they then output the per-source average AoI and the per-source CDF which is used by "numericalExample.m" script to obtain the performance metrics of interest.
