WebWhy is chordal hop propagation desirable? The signal experiences less loss along the path compared to normal skip propagation; The MUF for chordal hop propagation is much lower than for normal skip propagation; Atmospheric noise is lower in the direction of chordal hop propagation; Signals travel faster along ionospheric chords; E3B14: Webprobabilistic upper bounds for the hop domination number of a graph. Given a graph G and a positive integer k, the hop domination problem is to decide whether G has a hop dominating set of cardinality at most k. Henning and Rad [13] proved that the hop domination problem is NP-complete for planar bipartite graphs and planar chordal graphs.
