Create passwords.py to connect your wi-fi network with SSID and password.

Integrated Folder

Import this folder to your esp32

boot.py

This file consists with these componensts below:

• Network configulation
• Establish connection
• Flag
• main

Network configlation

import passwords from your passwords.py. Define your SSID_NAME_*.

Establish connection

Establish connection with your SSID_NAME_* by executing connect_*_wifi().

connect_*_wifi() calls wifiscan() searchs nearby Wi-Fi signals.

flag() decides whather activate 'cm_main.py' or 'ch_main.py'.

calc.py

This file normalizes 2 parameter values(battery, number of connectabele nodes) and calculate euclidian distance.

normalize()

Normalize battery and number of connectable nodes.

Reading battery and number of connectable nodes from 'node_data.csv', normalize these 2 parameters. Then, write the normalized data to 'normalized_node_data.csv'.

extract_from_csv()

extract_from_csv() extracts 2 values from 'normalized_node_data.csv' and call sim_score().

sim_score()

sim_score() calculates euclidian distance using given 2 arguments from extract_from_csv().
