Abstract

This paper presents graph coloring algorithms and their applications to the channel assignment problems. Two application problems of frequency assignment of low power FM broadcasting and reader collision problem of RFID system are modeled as graph coloring problems. Instead of performing an exhaustive search for the optimal result, we provide both search space reduction and variable ordering heuristics to obtain good approximate solutions. Constraint optimization modeling and variable ordering enforce the backtracking process in graph coloring algorithms, so the search space is greatly reduced and the approximate solution is found quickly. A great deal of outstanding work on graph coloring algorithms is described and applied to the simulation results.
