Instructions

use simulator.py to run python3 simulator.py <optional parameters>

Observe the outputs on terminal or read the sim_data.txt, sim_summary.txt

The default parameters are used in the test. If you want more data, see parameters

Recommend Parameters

--test_mode 0 --verbose 3 --algo_type 5

for random packet test

--test_mode 1 --verbose 3 --algo_type 5 --target_rate 10 --runs 5 --print_output False

varies the target_rate between 0-10

for constant packet test

--test_mode 2 --verbose 3 --algo_type 5
