The Award Ceremony of the 31st IEEE Real-Time and Embedded Technology and Applications Symposium (RTAS) has concluded, and it is our pleasure to announce the highlights of this year’s awards.
The RTAS 2025 Technical Program Committee nominated four papers for awards, evaluating them based on novelty, presentation, applicability to real-world applications/systems, and relevance and completeness of experimental evidence. The four papers were selected as Outstanding Papers and candidates for the Best (Student) Paper Award.
Best Paper Award
CROS-RT: Cross-Layer Priority Scheduling for Predictable Inter-Process Communication in ROS 2
Authors: Sohyun Kim, Juho Song, Kilho Lee, Sangeun Oh, and Hoon Sung Chwa
This paper tackles the challenges of achieving real-time guarantees in ROS2 due to unpredictable delays and priority inversions. CROS-RT, a cross-layer scheduler, ensures consistent priority-based scheduling across application, middleware, and kernel layers. Experiments show that CROS-RT significantly improves communication predictability, reducing the worst-case response time compared to baseline ROS2. The Best Paper Award committee was impressed by this paper’s practical significance and immediate, as well as long-term, impact on the field.
Best Student Paper Award
A Unified Framework for Quantitative Cache Analysis
Authors: Sophie Kahlen and Jan Reineke
This work unifies two approaches to cache analysis for non-LRU policies. It is applicable to microarchitectures with timing anomalies and enhances WCET analysis using existing persistence analyses for LRU. Experiments demonstrate that the precision of cache analysis for FIFO and MRU is comparable to that of LRU. The Best Paper Award committee viewed this paper as an excellent example of a well-integrated blend of theoretical results and implementation efforts, which embody the spirit of RTAS.
The Best Reviewer Committee evaluated six nominated reviews/reviewers based on criteria like review quality, completeness, and helpfulness to the authors. Four reviewers were recognized as Outstanding Reviewers and candidates for the Best Reviewer Award.
Best Reviewer Award
Zoe Stephenson, Rapita Systems, UK
RTAS is grateful to all members of the Technical Program Committee who volunteer their time to review submitted papers. It is particularly rewarding when industry members contribute to the conference and stand out in terms of reviewing excellence, both in thorough reviews and active participation in discussions. Thank you, Zoë!
We want to thank the members of the Award Committees and congratulate all award recipients on their achievements and thank you for your contributions to another successful RTAS!
