## 4 The Up/Down Mechanism of WiFi MAPs
### Algorithm Specification
For all cases we showed that MAPs can deactivate their WiFi interfaces, because OLSR always found a new route and our strategy forced them to receive authorization from their neighbours. We also did some GPS measures outdoors and showed that our PWMNS could deliver them efficiently. Finally we showed that our test platform could reach a power \begin{table}

saving of approximately 10 Watt every minute, amounted to 600 Watt-hour for every node of this type. We plan to extend the test platform to show that with more potential routes to be found by OLSR, our strategy will work better redressing the adverse effects of interferences.
