摘　　要：无线局域网是一种主流的网络接入技术,研究人员借助计算机仿真技术提出了许多优化方案来提高网络服务质量,如何对提出的优化方案进行测试和验证是一个急需解决的难题.本文设计并实现了低成本、多用途的MAC测试平台,该平台以Marvell88F6281和支持softMAC的无线网卡为关键硬件组件,由OpenWrt、MAC协议栈和网卡驱动程序组成软件平台,并通过移植mac80211和ath9k至该平台实现了AP和STA功能.由于该平台外围接口丰富,可完成目前市面多种接口无线网卡的验证测试工作.Wireless Local Area Network (WLAN)is a kind of popular network access technology.In order to improve the quality of services (QoS),researchers have proposed many optimized schemes with computer simulation technology. How to test and verify the proposed scheme is an urgent issue to be solved.In this paper,a low-cost and multi-purpose MAC Testbed is designed and implemented.The pivotal hardware module of this testbed is composed of Marvell 88F6281 and the softMAC wireless network card.The software testbed is consisted of MAC stack,the wireless network card driver and OpenWrt,thus AP and STA functions are implemented by transplanting the mac80211 and ath9k to the testing platform.Due to the rich peripheral interfaces of this testbed,it can complete the corresponding verification and testing of various interface wireless network cards in the present market.
