ABSTRACT

This paper studies the throughput of IEEE mmWave-WPAN based on the hybrid multiple access of CSMA/CA and TDMA. To study the throughput, we make a novel analytical model for the hybrid multiple access. Our throughput analysis shows that the throughput is highly affected by the access time of CSMA/CA. A larger access time of CSMA/CA will cause a lower data transmission time in TDMA, while a lower access time of CSMA/CA will also cause a higher collision that leads to increase the unused time for data transmission. This paper provides the approximated optimum access time of CSMA/CA maximizing the throughput. Furthermore, this paper introduces a private channel release time method for reducing collisions that highly improves the throughput of the mmWave-WPAN.
