摘要
随着嵌入式技术和无线AdHoc网络技术的发展,无线AdHoc网络应用成为研究的热点。文中设计了基于应用处理器MC9823MX21的无线AdHoc网络终端系统,论述了各个模块的设计思想,给出了设计结构原理框图。采用基于Memory接口的方式,首次将WT4无线网卡成功移植到i.MX21平台上。在嵌入式Linux系统上实现对无线通信模块的支持,成功构建了具有移动自组网和多跳传输的功能的无线移动AdHoc网络,并且实现了各个无线网络终端之间的数据传输通信。
The application of wireless AdHoc network become research point with the development of embedded technology and wireless AdHoc network technology.Design a wireless AdHoc network terminal system based on the application processor MC9823MX21,discuss the design idea of each module,and draw the block diagram of design structure.With the memory interface,it first successfully transplants wireless card WT4 to i.MX21 platform and adds the wireless communication module into the embedded Linux system.In this way,it constructs a wireless mobile AdHoc network possessing MANET and multi - hop transmission functions, making the data transmission communication among the wireless network terminals available.
