Performance Evaluation of Dynamic Parameter Controlled OF/TDMA Based on PR-DSMA

The next-generation wireless access system named DPC-OF/TDMA, which is capable of achieving 100 Mbps carrier bit rate under high mobility environment, has been proposed and is being developed. For the realization of this system, large size of cellular zone is required in order to increase system capacity. However, propagation delays between an access point (AP) and mobile stations (MSs) managed by the AP increase as the cellular zone size is large. These increased propagation delays falls system throughput. In this paper, application of PR-DSMA, which is robust against large propagation delays, to the MAC layer protocol of DPC-OF/TDMA is proposed to solve this problem. This paper also conducts performance evaluation in terms of automatic request control (ARQ) and cell radius by computer simulation
