1st International Workshop on
Testing Distributed Internet of Things Systems

Co-located with the 9th IEEE International Conference on Cloud Engineering (IC2E 2021)

The 1st International Workshop on Testing Distributed Internet of Things Systems (TDIS) will bring together researchers and practitioners who focus on simulations, models, hybrid testbeds, test frameworks, fault injection, monitoring tools, as well as IoT 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, network bottlenecks, and unnecessary energy consumption, while there are also 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 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, if IoT systems are to continuously optimize the operation of critical urban infrastructures such as public transport systems, energy grids, water networks, and medical infrastructures on the basis of collected sensor data, new versions of such IoT systems must be tested thoroughly before they can be deployed and relied on. The behavior of such critical IoT systems has to be tested under the expected distributed 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. In case that the workshop will have to take place virtually, we will make sure there will be ample opportunities for constructive feedback, lively discussions, and direct interactions.

Paper Submission

Authors are asked to submit papers in PDF via the submission system of the main conference, selecting the TDIS workshop. Papers should not exceed 6 double-column pages, including figures and tables, in the IEEE Manuscript Template for Conference Proceedings. LaTeX users must use \documentclass[10pt,conference]{IEEEtran}, without including the compsoc or compsocconf options. References can be additional pages. The submitted papers should include the names and affiliations of all authors. Submitted papers will be peer-reviewed by our Program Committee. Submissions should not have been published earlier and not be currently under review submission anywhere else. Accepted papers will be published with the main conference proceedings via IEEE Xplore.
