| Abstract: 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. |
