摘　　要：移动自组织网络(MANET)是当今网络通信领域的研究热点,但之前的研究多集中在MANET的物理层、媒体访问控制(MAC)、路由等方面,对在MANET中提供多媒体通信服务的研究较少。为了利用MANET提供高质量的多媒体通信服务,需要将现有通信架构进行改造,使之适合MANET环境。因此需要利用会话发起协议(SIP)在MANET中构建一个应用层对等网络(P2P),实现多媒体通信。文章提出了一个新的基于MANET的P2P组网模型——MAP,并在MAP的基础上,提出了基于MAP的SIP组网架构——MASIP。MASIP可以兼容现有的SIP设施,可以同时提供传统SIP和MASIP的P2P服务,充分考虑了MANET的自身特点,避免了直接采用SIP或其他P2P架构的缺陷,可以提供灵活、随时随地的通信服务。Mobile Ad Hoc Network （MANET） is currently a hot topic in the field of network communications. However, the previous MANET research focuses on the physical layer, Media Access Control （MAC） and routing, and concerns little about delivering multimedia communications services. It is necessary to change the existing communications architecture for offering high-quality multimedia communication services by MANET. Therefore, the Session Initiation Protocol （SIP） is used for building an application-layer Peer-to-Peer （P2P） network in MANET to fulfill multimedia communications. This article proposes a new MANET-based P2P networking model MAP, and a MAP-based SIP networking architecture MASIP. MASIP can be compatible with existing SIP facilities, and offer both traditional SIP and MASIP P2P services. Moreover, it takes MANET＇ s own features into full consideration, and avoids the defects caused by direct use of SIP or other P2P architecture. Therefore, MASIP can provide flexible communications services at any time and anywhere.
