Abstract

As the demand for broadband multimedia wireless is increasing, there is a great need for quality of service (QoS). The IEEE 802.11e workgroup proposes the hybrid coordination function (HCF) channel access mechanisms, which includes two mechanisms: enhanced distributed channel access (EDCA) and HCF control channel access (HCCA). The EDCA is a contention-based scheme and supports service differentiation through prioritiesed access to the wireless medium. The HCCA works under the control of a hybrid coordinator (HC) and provides a centralised polling scheme. In this paper, we evaluate and compare the performance of HCCA and EDCA for constant bit rate (CBR) traffic transmission. The results show that both access methods are able to carry the prioritized traffic.
