未来的作战网络需要具有低成本、能立即部署、自组织、健壮以及规模与密度可扩缩的特征。DARPA的下下代无线网络( WNaN)采用一种体系架构来迎接这些技术挑战，该架构首次在实际功能系统中呈现出几种创新的特征：动态频谱接入( DSA )、自适应多收发器频率指派、多信道媒体接入、高度可扩缩的路由以及容断组网( DTN)。文中介绍WNaN系统的网络体系架构，重点主要在于媒体接入和子网层。然后，简短地叙述这些关键协议如何协作工作、它们在该目标平台上是如何实现的。最后，将讨论WNaN对我军下一代战术网络设计的一些启发。

The future combat network needs to be low cost and instantly deployable, self-organizing, ro-bust, and scale with both size and density. In order to meets these challenges, DARPA's Wireless Net-work after Next( WNaN) uses an architecture that combines several innovative features for the first time in a real functional system: dynamic spectrum access ( DSA ) , adaptive multi-transceiver frequency assign-ment, multi-channel medium access, highly scalable routing and disruption-tolerant networking(DTN). This paper proposes the network architecture of the WNaN system, mainly focusing on the medium access and sub-network layers. It briefly describes how key protocols work in tandem, and how they are imple-mented on the objective platform. Finally, the paper discusses some guiding purpose.
