Call For Papers

Scope of the conference

RTNS is a friendly and inclusive conference with a great sense of community that presents excellent opportunities for discussion and collaboration. The current plan is for the conference to be delivered in a hybrid manner, with a mix of physical (at the University of Nantes, France) and virtual presentations, however due to COVID-19 the conference may have to move to fully virtual.

Original unpublished papers on all aspects of real-time systems and networks are welcome. For this year, RTNS particularly welcomes position papers and papers defining open challenges.

RTNS covers a wide-spectrum of topics in real-time and embedded systems, including, but not limited to:

• Real-time applications design and evaluation: automotive, avionics, space, railways, telecommunications, process control, multimedia.
• Real-time aspects of emerging smart systems: cyber-physical systems and emerging applications, real-time big data, real-time edge/fog and cloud computing, smart grid.
• Real-time system design and analysis: real-time tasks modeling, task/message scheduling, evaluation, mixed-criticality systems, Worst-Case Execution Time (WCET) analysis, quality of service, security.
• Software technologies for real-time systems: model-driven engineering, programming languages, compilers, WCET-aware compilation and parallelization strategies, middleware, Real-time Operating Systems (RTOS), virtualization, hypervisors.
• Formal specification and verification: application of formal models, such as model checking, satisfiability modulo theories or constraint programming, to solve real-time problems.
• Real-time distributed systems: fault tolerance, time synchronization, task/messages allocation, adaptability and reconfiguration, publisher/subscriber protocols, distributed real-time database
• Real-time networks: Networks on Chip (NoC), wired and wireless sensor and actuator networks, Time-Sensitive Networks (TSN), industrial IoT, SDN, 5G, end-to-end latency analysis.
• Hardware support for real-time systems: hardware/software co-design, power/temperature-aware techniques, design of predictable hardware, multi-core and many-core platforms, hardware accelerators, cache related issues, interconnect and memory.

Submission of papers

The papers are limited to 10 two-column pages (not including references) in ACM conference format. The proceedings will be published by the ACM ICPS (approval pending). A selection of the best papers will receive recognition as outstanding papers, and will be highlighted as such in the proceedings.

Authors of outstanding papers will be invited to submit an extended version of their work to a special issue of the Springer Real-Time Systems journal. The extended papers must have at least 35% new content. Best papers and best student papers awards will be presented at the conference, along with an award for the best presentation.

(Note that submissions are eligible for the best student paper award provided that the first author is a student as of the submission deadline).

RTNS 2021 will have the artifact evaluation for the accepted papers, to guarantee the availability of source code and data to replicate the experiments.
