Demo Abstract: Realistic Simulation of Radio Interference in COOJA

Carlo Alberto Boano, Kay Römer, Fredri Osterlind, Thiemo Voigt


Radio interference drastically affects the reliability and robustness of wireless communications. As wireless sensor network protocols are frequently designed and tested in simula-tion environments first, it is important to have simulation tools that provide means to study the impact of radio interference. Radio propagation models available in simulation environ-ments are however often too simplistic, and can hardly capture the complexity of the real world. To increase the realism of simulations, we incorporate recorded interference traces into existing simulation models. We extend the COOJA simulator with the generation of realistic interference sources in the simulation environment. We add new features, such as an interference-aware propagation model and loading of interference traces, which can be captured and recorded through a mote-based application. In our interactive demo, we show the generation of interference patterns produced by devices operating in the 2.4 GHz band such as microwave ovens, Bluetooth, and Wi-Fi. We will monitor, capture, and record the ongoing interference at runtime, and load the recorded traces in our extended COOJA version. We then show how to use the captured patterns to simulate and study the impact of radio interference on sensornet communications and routing trees.
