Event detection in wireless sensor networks is a sophisticated method for processing sampled data directly on the sensor nodes, thereby reducing the need for multi-hop communication with the base station of the network. In contrast to application-agnostic compression or aggregation techniques, event detection pushes application-level knowledge into the(More)
—In radio frequency based indoor human localization systems with body mounted sensors, the human body can cause non-line-of-sight (NLOS) effects which might result in severe range estimation and localization errors. However, previous studies on the impact of the human body only conducted static experiments in controlled environments. We confirm known(More)
—We present a technique to profile the energy consumption of real Wireless Sensor Network (WSN) applications. The introduced method is highly integrated into the system and allows the developer of WSN algorithms to analyze the power consumption almost without any additional effort. It can break the power consumption down to any desired level from(More)
