运动网络使用DTN技术的分析与研究

针对在一个由多种移动节点组成的运动网络中拓扑结构、链路质量和拥塞情况等随时间快速变化的问题,分析了DTN网络模型的特点与应用方法,集中讨论了运动网络中路由方式的选择和协议扩散机制的建立;针对保管转发技术完善了捆绑层协议构架,提出了分层的分布式数据存储转发技术进行各类数据的安全存储和转发,该技术能够应用于深空探测、应急最低通信和运动节电通信等网络工程之中。

Analysis and Study on DTN Technology for Dynamic Networks

According to the problem that in a dynamic network composed of multiple moving nodes,the topology,link layer quality and congestion state change quickly with time,this paper analyzes the characteristics and application area of DTN models and focuses on the discussion of how to choose the proper routing strategy and establish the protocol diffusing mechanism.According to the store-transfer technology,this paper proposes a better protocol frame of bundle layer and a layered and distributed technology to store and transmit various kinds of data.The technology can be applied to deep space exploration,emergency communication and dynamic networks projects,etc.
