Adjusting the power consumption of a solar energy powered wireless network node in accordance with weather forecasts

Abstract

We present how weather forecasts estimating the solar radiation for the following days at a given location can be used to adjust the power consumption of a wireless network node. The node is powered by a solar panel which recharges a battery. We discuss two methods to adjust the configuration of the wireless node according to weather forecasts. We are using OLSR routing parameters and hardware adjustments to control the amount of energy needed. One method calculates the available energy, the other uses a naive Bayesian classifier to choose the optimal configuration. © Springer Science+Business Media B.V. 2008.
