For dynamic systems, it is mandatory that all components operate on predictably “fresh” data. This requirement constitutes a challenge, in particular, when Internet-based or wireless communication is involved. We propose X-Pace, an approach based on cross-layer pacing, to achieve predictably low communication latency in the presence of varying network channel properties and node performance.
