Title: “Dependable Internet of Things for Safety-Critical Applications”


  • Abstract: Wireless networked embedded systems are increasingly used for safety-critical applications such as smart production or networked cars, where failures may have severe impact. Therefore, strict dependability requirements have to be met. This is difficult to achieve, however, as these applications often operate in harsh environments or are exposed to attacks. Moreover, a system is only as dependable as its weakest part, so all relevant aspects of an IoT system have to be dependable. In this talk, I present recent research results that increase the dependability of relevant aspects of the IoT. Specifically, we present a single-anchor approach to robust and accurate localization using Ultra-Wide-Band radios, an approach to automatically learn models of protocols used in the IoT in order to formally verify their correct implementation and interoperability, as well as how to use this method to verify the correctness of networked control systems using truck platooning as an exemplary use case.
