Wireless sensor and actuator networks (WSAN) for industrial applications usually have tighter requirements on dependability, synchronization, and real-time capability as compared applications in environmental monitoring or health care. For WSAN research and development, testbeds are a valuable tool as they enable controlled operation under conditions close(More)
In this paper, we present a methodology to establish an accurate and power-aware simulation of wireless sensor networks. As the design of software applications running on resource-constrained sensor nodes mainly influences both timing and power consumption in the network, it is crucial to include these components in the simulation. Besides considering the(More)
After a decade of research in the field of wireless sensor networks the energy consumption remains the dominating constraint. Complex algorithms with non-negligible runtimes must be processed by resource-limited nodes, and therefore require in-depth knowledge of the temporal behavior of the software and hardware components. However, state-of-the-art(More)
In a wireless sensor network, the energy consumption of the nodes continues to impose a tight constraint. Researchers have therefore proposed several MAC protocols to decrease the energy consumption of the radio transceiver, which has increased the complexity of the firmware running on the nodes. In this paper, we show the consequences of ignoring runtimes(More)
After a decade of research in the field of wireless sensor networks (WSNs) there are still open issues. WSNs impose several severe requirements regarding energy consumption, processing capabilities, mobility, and robustness of wireless transmissions. Simulation has shown to be the most cost-efficient approach for evaluation of WSNs, thus a number of(More)
