摘　　要：由于MANET自组织、无中心等特点,传统的VoIP体系结构不能直接应用在MANET之上,这就要求对传统VoIP系统进行一定的改造,使之能够适应MANET环境。本文提出将P2P的簇状组网结构引入SIP,从而可以在MANET上构建基于SIP的可灵活扩展的VoIP通信系统,分析了在该架构中的主要操作的典型工作机制,采用本方案的VoIP系统既可以适应MANET环境的需求,又可以与现有的SIP系统无缝通信。本文最后展望了未来的研究方向。Keywords Traditional VolP architecture cann＇t be brought to MANET environment because of the characteristics of MANET, such as self-organizable, centraless, etc. The alteration of traditional VoIP architecture is obligatory for the sake of be seasoned with MANET environment. This paper proposes a scheme of design VoIP system on MANET using SIE The scheme relies on extension SIP UA and the introduction of clusting in SIE We have also analyse the workign mechanism of the main functions. The VoIP system who adopt the architecture can either fit MANET or communicate with current SIP system seamlessly. We also have an outlook of the future work at the end of the paper.
