A New Model Approach for the Prediction of the Incoming Energy for Solar Based Wireless Sensor Nodes

Christian Viehweger, Olfa Kanoun

Abstract

Wireless sensor networks can be used to monitor environmental conditions over a large area. The use of solar cells for their power supply makes them independent from stationary power sources and batteries. Photovoltaik powering of sensor nodes requires new strategies for the usage of energy. As, due to clouds and other shadowing effects, the source is not constantly available, an intelligent management is required. The energy management must have a more complex functionality than common ones that use only DC/DC and storage strategies or MPP tracking as optimization. The energy management needs to have the functionality of predicting the incoming power to decide about the state of function of the autonomous system. This paper presents an approach for the modeling of the incoming energy as basis for the prediction.
