Bandwidth-efficient burst error tolerance in TDMA-based CAN networks
Abstract
Many distributed control systems employ TDMA-based communication over CAN in order to meet realtime constraints. Whilst this form of media access control brings several timeliness benefits, studies have also illustrated negative effects on transmission reliability. This paper extends the ‘window transmission’ technique which was recently proposed by the authors to help overcome this problem in TDMA-based networks to include the effects of correlated (burst) errors. This paper employs a simple Markov model to describe burst error behaviors in a CAN network, and the model is used to develop an algorithm for calculating TDMA slot sizes which aim to provide prespecified statistical guarantees of message delivery. Computational results are presented which indicate that the technique can reduce the amount of bandwidth needed for specified reliability levels by a significant factor when compared to the use of message duplicates. The paper is concluded with an empirical study which provides further supportive evidence for the described technique.

The Gilbert-Elliot model is an appropriate choice for modeling the impact of errors within a noisy wireless channel.
“This model is extensively simulated in research studies to find packet losses [52], frame losses [53], and bit losses [54], hence making it an appropriate choice for modeling the impact of errors within a noisy wireless channel [55].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
