Development of ralink's wireless network interface card based on uclinux

The design of Wireless Network Interface Card device driver, based on PCI bus, is the key part of WMN(Wireles Mesh Network). MIPS and uclinux based development environment, Network Interface Card device driver RT2860 oriented are designed and realized. Combining to network protocol of IEEE 802.11, this paper focuses on the initialization, opening, transmission and receive, interrupt handling of RT2860. The The data transmission rate and performance of the network are tested and evaluated. The results shows that this device driver works reliably, rebustly and efficiently.
