Above increasing autonomy of wireless sensor networks used for windmill monitoring

This paper presents considerations of using wireless sensor networks for monitoring conditions within wind farms, taking into considerations the specific of such applications. In these scenarios, which are intended to cover a lot of ground or even operate in difficult radio environments with strong attenuation, the simple and direct communication between source and destination is not always possible, due to the distance restriction. To overcome these facts, there are required multi-hop algorithms considering the optimization of consumed energy, to enhance the network lifetime. In order to enhance overall network lifetime two methods were used, based on data aggregation and routing techniques.
