无线通信的发展使得Ad-hoc的路由协议受到广泛关注，AODV协议是移动自组织网络中应用最广泛的按需路由协议，能有效的防止路由环路，适用于多种网络拓扑场景。同时，嵌入式开发在移动多媒体平台中起到重要作用，可实现专用、简单、高效的应用层服务平台。本文在基于Linux操作系统的嵌入式平台中搭建了AODV路由协议模块，实现了无线网卡rt3070.ko和自组织路由协议kaodv.ko的交叉编译和移植，验证了嵌入式平台下通过AODV无线路由协议进行组网的可行性和可靠性。通过对相关网络参数的分析，为Ad-Hoc的嵌入式多媒体应用提供了有益参考。%The development of wireless communication, people pay attention to the Ad-hoc routing protocols. AODV protocol is one of the on-demand Ad-hoc routing that is widely used. It can prevent routing loops effectively, which is suit for a variety of network topologies scenes. Meanwhile,the embedded system makes a contribution to developing the mobile multimedia platform, and it will play an important role to realize the specific, simple and efficient service platform at application layer. In this paper, the AODV routing protocol modules at embedded platform based on the Linux operating system are built. A self-organizing wireless network according to cross compiling rt3070.ko and kaodv. ko are achieved. The feasibility and reliability of wireless network using routing protocol AODV at the embedded plat-form are verified. Through an analysis of the relevant network parameters, a useful reference for Ad-hoc embedded multimedia applications is provided.
