TL;DR: Simulation results show that the system's traffic-carrying capacity can be increased by about 10% by the use of this algorithm, and that the gain is additional to the improvement obtained from the channel-borrowing strategies.

Abstract: An algorithm for allocating nominal channels according to traffic distribution is designed. The algorithm attempts to minimize the average blocking probability as nominal channels are allocated one at a time. Simulation results show that the system's traffic-carrying capacity can be increased by about 10% by the use of this algorithm, and that the gain is additional to the improvement obtained from the channel-borrowing strategies. If the effect of shadow blocking is considered in the assignment of channels, only a very small increase in the traffic capacity is observed. >
