Authors: Dirk Ziegenbein, Selma Saidi, Xiaobo Sharon Hu, and Sebastian Steinhorst

Published in: Dagstuhl Reports, Volume 9, Issue 12 (2020)


Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 19502 "Future Automotive HW/SW Platform Design". The goal of this seminar was to gather researchers and practitioners from academia and industry to discuss key industrial challenges, existing solutions and research directions in the design of future automotive HW/SW platforms, particularly focusing on predictability of systems regarding extra-functional properties, safe integration of hardware and software components and programmability and optimization of emerging heterogeneous platforms.

Reliable Dynamic Packet Scheduling over Lossy Real-Time Wireless Networks

Authors: Tao Gong, Tianyu Zhang, Xiaobo Sharon Hu, Qingxu Deng, Michael Lemmon, and Song Han

Published in: LIPIcs, Volume 133, 31st Euromicro Conference on Real-Time Systems (ECRTS 2019)


Abstract
Along with the rapid development and deployment of real-time wireless network (RTWN) technologies in a wide range of applications, effective packet scheduling algorithms have been playing a critical role in RTWNs for achieving desired Quality of Service (QoS) for real-time sensing and control, especially in the presence of unexpected disturbances. Most existing solutions in the literature focus either on static or dynamic schedule construction to meet the desired QoS requirements, but have a common assumption that all wireless links are reliable. Although this assumption simplifies the algorithm design and analysis, it is not realistic in real-life settings. To address this drawback, this paper introduces a novel reliable dynamic packet scheduling framework, called RD-PaS. RD-PaS can not only construct static schedules to meet both the timing and reliability requirements of end-to-end packet transmissions in RTWNs for a given periodic network traffic pattern, but also construct new schedules rapidly to handle abruptly increased network traffic induced by unexpected disturbances while minimizing the impact on existing network flows. The functional correctness of the RD-PaS framework has been validated through its implementation and deployment on a real-life RTWN testbed. Extensive simulation-based experiments have also been performed to evaluate the effectiveness of RD-PaS, especially in large-scale network settings.
