A middleware protocol for time-critical wireless communication of large data samples

Jonas Peeck, Mischa Mostl, Tasuku Ishigooka, Rolf Ernst
2021 2021 IEEE Real-Time Systems Symposium (RTSS)  
We investigate some technical limits of such a protocol and compare it to existing error protocols in the software stack and in the wireless protocol and combinations thereof.  ...  The protocol uses a custom retransmission scheme, exploiting the latency requirements on sample level for frame level scheduling. It can be integrated into the popular DDS middleware.  ...  We acknowledge the financial support for the project by the Federal Ministry of Education and Research of Germany (BMBF).  ...
