2nd International Workshop on
Testing Distributed Internet of Things Systems

September 27, 2022, in Pacific Grove, California

Co-located with the 10th IEEE International Conference on Cloud Engineering (IC2E 2022)

The 2nd International Workshop on Testing Distributed Internet of Things Systems (TDIS) will again bring together researchers and practitioners who focus on simulations, models, hybrid testbeds, test frameworks, fault injection, monitoring tools, as well as IoT experiments and applications, providing a forum for ongoing work presentations and discussions.

Call for Papers

The Internet of Things (IoT), cloud computing, and machine learning will allow for more adaptive cities, houses, and infrastructures. Yet, this vision of intelligent cyber-physical systems will not be implemented with centralized cloud resources alone. Such resources are simply too far away from sensor-equipped IoT devices, leading to high latencies, bandwidth bottlenecks, and unnecessary energy consumption. Additionally there are often privacy and safety requirements mandating distributed architectures. Therefore, new distributed computing paradigms and system architectures are currently emerging for the IoT that promise to provide computing and storage in proximity of edge devices.

However, the resulting heterogeneous, distributed, and dynamic environments pose significant challenges to the performance, dependability, and efficiency of distributed systems. It is also far less clear how to best create test environments and integrate domain-specific simulations to be able to efficiently assess the behavior IoT systems will exhibit in the field. Yet, continuous testing in realistic test environments is essential for many IoT systems. For instance, IoT systems might be deployed to continuously optimize the operation of critical urban infrastructures, including public transport systems, energy grids, water networks, and medical infrastructures. New versions of such IoT systems must be tested thoroughly before they can be deployed and relied on. Furthermore, the behavior of such IoT systems has to be tested under the expected computing environment conditions, including variations of such conditions, given the inherently unsteady nature of IoT environments.

The TDIS workshop aims to provide a forum for current work by researchers and practitioners in the different research areas and application domains connected to testing IoT systems. We welcome submissions that describe initial ideas and visions just as much as reports on novel approaches, practical tools, and completed projects.
