MQTT-EES

Start in the root project directory. The following experiment modes are available: energy,lifespan

The following schedulers are supported: ees, random, mqtt

For more help with using the simulation flags run: python3 start.py --help

Example: 2 Experiments

Energy Consumption Demo

python3 start.py -config config/example_energy_pub.ini -mode energy -scheds ees,random

Lifespan Demo

python3 start.py -config config/example_lifespan.ini -mode lifespan -scheds ees,random,mqtt

Reading Results Column Headers

The following headers are standard across all results csv files:

algo_name, time_end, num_round, num_topic, num_pubs, num_subs, total_energy_consumption

time_end - if a single device's battery reduces to 0 as the tasks generated for the observation period are allocated, then the simulated algorithm ends execution and logs the associated shutdown time

num_round - the simulated round number

total_energy_consumption - the total amount of energy the system of devices used to perform all sensing tasks within the observation period

Additional values appended to each row are the energy consumptions of num_pubs devices at the end of round num_round

Example: Reading Results

For example: ees,NA,2,8,3,8,1.0035000000000007,0.3405000000000002,0.32750000000000024,0.33550000000000024

• algo_name: ees
• time_end: NA (the system did not shut down)
• num_round = 2
• num_topic = 8
• num_pubs = 3
• num_subs = 8
• total_energy_consumption = 1.0035000000000007 The system tracked 3 devices' consumptions: 0.3405000000000002,0.32750000000000024,0.33550000000000024 (You can double check that the sum is equivalent to the value in the total_energy_consumption column)
