| Abstract: In this paper we compare the performance of two TDMA-ATM-based access methods for indoor broadband wireless systems. The first scheme is non-uniform polling and the second is reservation. Although the non-uniform polling has a lower delay, it has the disadvantage of requiring the base station and remote to switch between receive and transmit modes quickly. A specific reservation-based protocol is presented in this paper which applies bandwidth allocation and admission control techniques in a manner similar to the non-uniform polling. The performance of both methods is compared in terms of cell loss rate of delay sensitive applications and the mean cell delay. Furthermore, the analysis and formulations that were presented in previous papers are extended to account for the effect of offered load on the interference power, channel failure rate and the channel utilization upper bound under specific guaranteed quality. |
