A graph coloring problem usdul in deciding whether a set of call requests in cellular radio is compatible with frequency use constraints is introduced. Lower and upper bounds are obtained for the hexagonal cell case typical of raany urban cellular systems. These bounds are on the number of frequenci

We discover a surprising connection between graph coloring in two orthogonal paradigms: parallel and on-line computing. We present a randomized on-line Ž . coloring algorithm with a performance ratio of O nrlog n , an improvement of log n factor over the previous best known algorithm of Vishwanathan
