Abstract

Internet of Things (IoT) applications in several domains such as surveillance of civil infrastructure, smart grids, and smart healthcare are of utmost importance for our society and require dependable performance. Guaranteeing that application-specific dependability requirements are met is however still an open research challenge. The IoT indeed exposes highly resource-constrained computing devices to harsh environmental conditions (e.g., heat, mechanical shock, electromagnetic radiation) and physical attacks. Unfortunately, traditional methods to withstand these threats heavily rely on redundancy, a concept that is incompatible with the resource constraints of common IoT devices.
In this article, we illustrate our efforts in providing methods and tools to predict, guarantee, and raise the level of dependability of the IoT. We first outline our contributions in the area of dependable wireless networking and describe a cost-effective solution allowing to guarantee that IoT applications meet specific performance requirements despite the challenging interaction of low-power wireless networks with their surrounding environment.
We then argue that dependable networking alone is insufficient to guarantee the correct operation of a complex IoT system, and outline how we join different scientific disciplines in a long-term endeavor and work towards a coherent view of dependability.
