Wireless sensor networks, which are composed of advanced MEMS (Micro-Electro-Mechanical-Systems) called sensor nodes, has been broadly researched as ad-hoc networks recently. Since sensor nodes are powered by limited-life batteries and are usually deployed in severe environments, they need to be able to conserve their power consumption as well as guarantee broad coverage and connectivity. In active sensor networks, such as RFID sensing systems, shorter sensing and communication ranges will result in a higher measuring precision and more efficient energy dissipation. In this paper, we propose a novel self-controlling method for sensor nodes to decide the most appropriate sensing radius, communication radius, and an active/sleep schedule simultaneously. The energy-saving effect is proved in our simulation section.
