To meet strict dependability requirements in hostile and highly-varying environments, IoT communication protocols need to be carefully tuned in relation to the expected environmental changes. However, this is difficult to attain, as every application has unique properties and requirements. Tuning communication protocols correctly requires indeed significant expertise as well as a clear understanding...
The number of sensors pervading our everyday life, e.g., in smartphones, cars, and buildings, is constantly increasing. These sensors, which are typically embedded into resource constrained devices such as sensor nodes or smartphones, allow measuring the state of the entities they observe or are attached to. If this information is accessible via the Internet, they contribute to the Internet of Things...
Temperature strongly affects the operation of integrated circuits, and its impact has been largely investigated on a device level. However, the impact of temperature variations on networks of multiple devices is far less understood and requires investigation. We aim to close this gap and analyse the impact of temperature fluctuations on low-power wireless sensor networks, a key enabling technology...
Many enterprise applications can benefit from the use of wireless sensors, for example for monitoring location and state of goods. While modern backend IT systems use elaborate Service Oriented Architectures based on Web Services, the resource constraints of sensor nodes require highly optimized embedded programming and proprietary networking protocols. This paper aims at bridging this gap by extending...
