On the span in channel assignment problems: bounds, computing and counting
- Abstract:
-
The channel assignment problem involves assigning radio channels to transmitters, using a small span of channels but without causing excessive interference. We consider a standard model for channel assignment, the constraint matrix model, which extends ideas of graph colouring. Given a graph G = (V,E) and a length l(uv) for each edge uv of G, we call an assignment φ :V → {1,...,t} feasible if | φ (u)- φ (v)| ≥ l(uv) for each edge uv. The least t for which there is a feasible assignment is the...
