An energy aware self-configured wireless sensor network

Recent years have shown that wireless communication are becoming more popular in professional, academic and every day applications. A wireless sensor node is usually autonomous, advanced device with limited power source. This limited power source makes the topology control a crucial technique, which allow the network to obtain energy efficiency without affecting the network´s connectivity and sensing coverage. The article demonstrates the energy efficient topology control mechanism, which allow a majority of network nodes stay in sleeping mode and do not affect the connectivity and sensing coverage. The result in energy consumption of the nodes and network lifetime are exposed and compared to different approaches.
