摘要：
In this paper, we investigate the ability of the standard IEEE802.11e to support Quality of Service (QoS) in wireless ad-hoc networks. Inspired by IEEE 802.11e, we propose the Dual-channels Request to send -RTS, Clear to send - CTS, and Ensure to send - ETS (DRCE) scheme for effective quality of service (QoS) support in mobile ad hoc networks. We evaluate the performance of IEEE 802.11e and DRCE by simulation and find that the DRCE outperforms the IEEE 802.11e protocol in terms of average packet delay and network throughput by easing the "hidden terminal", and "exposed terminal" problem. Furthermore, the DRCE optimizes the QoS performance for different priority packets compared to IEEE 802.11e.
