延迟容忍网络(DTN)试图扩展传统网络方法的覆盖范围，其中节点间歇连接，并且从源到目的地的端到端路径并不总是存在。真实的网络，如军事、各种传感器、灾后管理、深空通信、车载自组织(VANET)网络，都是DTN的一些例子。我们的工作主要集中在不同的基于洪泛的DTN路由方案在灾后场景中的适用性。考虑了集群移动模型，它更真实地映射了人类的移动，而不是灾难场景中的任何其他移动。在此基础上，根据灾难类场景定制了簇的移动性模型，并在一个模拟器中对缓存大小、传输距离、节点速度和密度等约束条件下的传输概率进行了仿真。并分析了异质节点对投递概率的影响。
Delay-tolerant Networking (DTN) is an attempt to extend the reach of traditional networking methods where nodes are intermittently connected and an end-to-end path from source to destination does not exist all the time. Real networks like military, various sensors, post disaster management, deep space communication, Vehicular ad-hoc (VANETs) networks, are some examples of DTN. Our work mainly concentrates on the applicability of different flooding based routing scheme of DTN in post disaster scenarios. Cluster mobility model which maps human mobility more realistically rather than any other mobility in the context of disaster scenario has been considered. Further we have customized cluster mobility model according to the disaster like scenario and performed the simulation for delivery probability with respect to various constraints like buffer-size, transmission range, speed and density of nodes in ONE SIMULATOR. We also analyze the effect heterogeneous nodes in delivery probability.
