Dynamic allocation of packet reservation multiple access carriers

The author studies the performance of a high capacity metropolitan microcellular radio network using computer simulation. Packet reservation multiple access carriers are dynamically assigned or released depending on current teletraffic loading conditions. Significant performance improvements are obtained using a 2-stage costing strategy which attempts to balance call blocking probabilities against packet dropping rate, thereby leading to more efficient utilisation of channel resources. The author achieves 40 to 50% improvements over a fixed allocation scheme in terms of the blocking probability performance, by soft assigning carriers to the microcells and performing a 2-stage dynamic carrier allocation procedure based on a simple costing algorithm which attempts to pack co-carrier cells as closely as possible
