Priority-based dynamic carrier allocation strategies can be classified into three categories: static-priority, dynamic-priority, and hybrid-priority strategies. Strategies based on static priorities do not consider the local carrier reuse conditions, while dynamic-priority strategies do take these conditions into consideration. Intuitively, one would expect dynamic-priority strategies to perform better than static- and hybrid-priority strategies, but in the literature it is the other way around-existing dynamic-priority strategies are out-performed by some static- and hybrid-priority strategies. We propose a dynamic-priority strategy which is a significant improvement over all existing strategies. Under various traffic conditions, our simulation results indicated that the proposed strategy could reduce the call blocking/failure rate by a margin ranging from 15% to 95%
