Modeling Directional Communication in IEEE 802.15.3c WPAN Based on Hybrid Multiple Access of CSMA/CA and TDMA

摘要

This paper focuses on the performance of the hybrid multiple access of CSMA/CA and TDMA, namely CSMA/CA-TDMA, in the 802.15.3c WPAN. A contribution of this paper is to provide an analytical model to study the system throughput of CSMA/CA-TDMA. A key property of the 802.15.3c WPAN is the directional communication due to the directivity of the mmWave radio. Another contribution is to analyze the system throughput for directional communication based on CSMA/CA-TDMA in the 802.15.3c WPAN. Numerical results show that the large number of the directions supported by the PNC could be a high overhead in the network as well as CSMA/CA-TDMA has higher system performance rather than CSMA/CA in case of happening high collisions.
