Abstract:In this paper, two new channel assignment algorithms are proposed. The first one is demand priority-based FCA algorithm, which gives the first priority to the highest demand cell, and uses a non-iterative method which has less computation time than the iterative methods. This algorithm is applied to the 5-benchmark problems, and the results show that this algorithm can achieve the optimal required number of frequencies specified in each problem without blocking. The second algorithm is new channel assignment algorithm with borrowing based on the demand priority-based FCA algorithm but assuming that the traffic is changing dynamically, its results show an obvious reduction in the average call blocking probability, so the spectrum utilization efficiency will be increased.
