摘　　要：针对基于延迟/中断容忍网络DTN(Disruption/Delay Tolerant Network)与移动无线自组网MANET(Mobile Ad-hoc NETworks)混合异构网络建立问题,提出了一种混合异构网络模型架构,用于将两种已经被广泛应用的网络架构MANET网络和DTN整合到一个能够利用两者优势的统一网络架构中。MANET由于高效、方便等特点被广泛应用,但是由于节点的移动可能会导致节点之间的链路脆弱和长时间断开的可能,导致MANET效率低下甚至无法正常工作。DTN的解决方案是使用"存储-携带-转发"传输模型代替端到端的IP传输模型,即使存在间歇性连接,也能维持数据的传输。基于DTN与MANET的网络协议栈特点,通过将应用层与适配层结合,合理利用两者的优势建立了混合网络模型架构。最后,对该架构模型进行实现,并进行了简单的评估,说明了该架构的潜在优势。In order to solve the problem of how to establish a hybrid heterogeneous network based on DTN(delay tolerant networks)and MANET,hybrid heterogeneous network model architecture for integrating MANET and DTN into one network architecture is proposed.This unified network can give full play to the advantages of both.Mobile wireless ad hoc network(MANET)is widely used due to its high efficiency and convenience but due to the mobility of the nodes,the links between the nodes are weak.DTN^s solution is to use the"storage-carry-forward"transport model instead of the end-to-end IP transport model.DTN uses this model to maintain data transmission even with intermittent links.According to the characteristics of the network protocol stack of DTN and MANET,this paper makes a reasonable use of the advantages of both to establish hybrid network model architecture.The model combines the application with the adaptation layer and selects efficient network architecture to transfer data to the destination node.Finally,the architecture model was implemented and a simple evaluation was performed to illustrate the potential benefits of the architecture.
