Introduction
The problem
I communication between WSN nodes could be problematic
I communication links suffer from quality, symmetry and noise
I high transmission power cause more trouble than help
I high transmission rates degrade communication

Introduction
RSSI, LQI and PRR
I show only a part of picture
I no globally suitable thresholds
I huge temporal characteristics
We need adaptation
