Highway vehicle scenario where the outage probability and the blockage duration are computed theoretically using Markov Chain. To validate our calculations, we run simulations using real world vehicle class dimensions. We use a deterministic, geometry based LOS channel, where the communicating vehicle said to be out of service when the LOS link between the vehicle and roadside units (RSUs) are blocked by other vehicles traveling on adjacent lanes.
To do the thoretical calculations on HPC,
git clone https://github.com/mustafafu/markov-vehicular.gitcd to theory folder,
sbatch --array=1-5 submit_theory.sbatchwhere each instance computes one combination of parameters:
- height of the RSUs
- height of the communicating vehicle
- in which lane the communicating vehicle travels. (always on lane 4 now but can be changed)
To reproduce the experiment on HPC,
git clone https://github.com/mustafafu/markov-vehicular.gitcd to Simulation folder,
sbatch --array=1-250 submit.sbatchwhere the array input can be any multiple of the full parameter sweep space length. for example, to try 5 different BS heights and 1 to 5 number of RSUs in the coverage area, a job can be submitted with arrays 1-25. To have more data, any multiple of 25 can be submitted and combining script can be used to process the data afterwards.
