| Summary: | 碩士 === 國立中山大學 === 資訊工程學系研究所 === 92 === This paper proposed BRQ (Bandwidth-Reservation QoS scheme) for mobile Ad-Hoc wireless network. Unlike many schemes about IFS or backoff time interval of DCF in IEEE 802.11, BRQ uses the bandwidth reservation mechanism to support QoS. Because of the compatibility of BRQ with other schemes, we believe that BRQ scheme can achieve higher performance by integrating with other schemes.
We evaluate the performance of BRQ, DCF in IEEE 802.11, EDCF in 802.11e, and BRQ+ (the combined scheme of BRQ and EDCF) in terms of their differentiation capability, network throughput, and average end-to-end delay. The simulation results demonstrate the effectiveness of the BRQ scheme and show that the BRQ+ scheme can achieve higher performance by integrating BRQ and EDCF.
