摘要
针对目前多数无线网络通信依赖于接入点(AP,access point)的现状,采用ARM9处理器(S3C2440)与嵌入式Linux操作系统相结合的技术,组建了Ad-Hoc无线网络通信系统。重点对无线网卡驱动程序进行了深入分析,实现了无线网卡在Linux环境下的移植,通过移植无线网络配置工具使无线网卡工作于Ad-Hoc模式。Ad-Hoc无线网络性能测试表明,该系统满足点对点CIF格式已压缩视频数据流的实时传输要求,具有较好的实际应用价值。
Differing from most of the wireless networks in which the access points（AP） are necessarily required,an Ad-Hoc wireless networks is constructed upon the adoption of ARM9 MCU（S3C2440） and embedded Linux operating system without the needs of access points.The wireless network card driver is analyzed in depth for the purpose of the transplanting of wireless network card into Linux OS,and wireless configuration tools are transplanted into the embedded system to make the wireless network card working in the Ad-Hoc mode.Performance test over Ad-Hoc wireless network verifies that this system is qualified for the real time transmission of compressed video data in CIF format,and is practical for various industrial applications.
