Online frequency allocation in cellular networks
Joseph Chan, Francis Y. L. Chin, Deshi Ye, Yong Zhang · 2007
Given a mobile telephone network, whose geographical coverage area is divided into cells, phone calls are serviced by assigning frequencies to them, so that no two calls emanating from the same or neighboring cells are assigned the same frequency. Assuming an online arrival of calls and the calls will not terminate, the problem is to minimize the span of frequencies used.
