Power output level is set to lowest
possible level that still ensures
successful transmissions.
Data rate is set to MAX (1 Mbps)
Interference is detected
Data rate is dynamically reduced to 250
Kbps for more robustness

Power output level is dynamically
increased to overcome the interference

1 Mbps and 250 Kbps depending on the
environment to maximize sleep time and
reduce power consumption

Should a node detect that its power
output is excessive, it will dynamically
reduce its power output to conserve
power
