A novel microprocessor interface circuit is described which can alternately emit and detect light using only an LED, two digital I/O pins and a single current limiting resistor. T...
Designing for non-verbal communication using e.g. gestures and other bodily expressions is difficult. Hardware and software need to be co-designed and harmonize in order to not th...
ion can improve performance without significantly breaking layered abstractions; explicit bursts are preferable to steady, constant bitrate traffic. Furthermore, the vagaries and c...
We propose several localized sensor area coverage protocols, for arbitrary ratio of sensing and transmission radii. Sensors are assumed to be time synchronized, and active sensors...

Abstract. We propose a model for communication in single-hop wireless sensor networks and define and evaluate the performance of a robust, energy balanced protocol for a powerful a...
