中文摘要:

在两个无线本地区域网络(WLAN ) 和活动特定的网络(MANET ) , IEEE 802。11e 媒介存取控制(MAC ) 协议为服务(QoS ) 的有效质量被建议解决方案。很多研究被做了提高 802 的表演。在由独立地调整竞争窗户(CW ) 的 MANET 的 11e 在每个节点的每个存取范畴(交流) 的尺寸。没有在高优先级流动和更低的优先级流动之间的合作,然而,高优先级流动的 QoS 目标不能有效地完成。在这篇文章,模糊逻辑基于合作 MAC 协议(FLCMAC ) 被建议在网络流动之中合作并且动态地调整影响高优先级流动满足他们的 QoS 要求的每低优先级流动的存取概率。模拟结果与提高的分布式的隧道存取(EDCA ) 相比显示那 802 的计划。11e, FLCMAC 一致地为佼佼者,以在在单个跳跃和多跳跃情形的中等、重的背景交通下面的产量和延期。

英文摘要:

In both wireless local area networks(WLAN) and mobile ad hoc networks(MANET), the 1EEE 802.11e medium access control (MAC) protocol is proposed for an effective quality of service (QoS) solution. A number of studies have been done to enhance the performance of 802.11e in MANET by independently adjusting contention window (CW) size of each access category (AC) in every node. However, without the cooperation between the high priority flows and lower priority flows, the QoS goal of high priority flows cannot achieve effectively. In this article, a fuzzy logic based cooperative MAC protocol (FLCMAC) is proposed to cooperate amongst network flows and dynamically adjust access probability of each low priority flow affecting the high priority flows to satisfy their QoS requirement. The simulation results indicate that compared to the enhanced distributed channel access (EDCA) scheme of 802.11e, the FLCMAC consistently excels, in terms of throughput and delay under moderate and heavy background traffic both in single-hop and multi-hop scenarios.
