摘　　要：给出一种嵌入式Linux下USB接口的Chirp无线通信网卡驱动的设计与实现。分析了Linux下无线网卡的驱动模型,为含有微处理器、射频发射模块和USB接口的无线网络节点编写网卡驱动。与嵌入式Linux系统配合,成功组建了嵌入式AODV自组织无线网络。测试效果表明:该网卡驱动实现了上层TCP/IP应用的透明网络传输,下层实现了基于AODV路由的自组织多跳网络通信,提高了无线节点应用的可移植性和复用性。This paper introduces the design and implementation of Chirp USB wireless network card driver in embedded Linux operating system. We analyze the driver model of wireless network card in Linux, and then the card driver is written in the wireless network nodes which contains microprocessor, RF transmitter module and USB interface. Cooperated with embedded Linux system, the system sets up the embedded AODV self-organized wireless network successfully. Test results show that the network card driver in the upper layer has achieved TCP/IP application transpatrent network transmission, in the lower layer it has realized self-organization and multi-hop network communication based on AODV routing, and it improves the portability and reusability of the application of the wireless transceiver.
