Transmission power control can significantly improve energy-efficiency of wireless sensor network communications. Power consumption models are typically based on dependence of channel attenuation on distance. However, in practice, information on distance is usually not available and the dependence of channel attenuation on distance is not sufficiently accurate. Therefore, we propose more accurate...
Transmission power control can significantly improve low-power wireless sensor network communications energy-efficiency. Power consumption models usually used to analyze various techniques for energy-efficient transmission are based on distance-dependent channel attenuation. In practice, distance is often not available and the dependence is not sufficiently accurate. Therefore, we propose more accurate...
In this work a wireless sensor network has been integrated in a textile-reinforced composite. It has been shown that an optical IrDA data transmission between an IrDA transceiver which is part of the sensor network and an external IrDA receiver is possible over a distance of a few ten centimetres. A special IrDA controller was developed to reduce power consumption and the number of components. All...
