DTNSim2 is a simulator for Delay-Tolerant Networks (DTNs) written in Java. It is based on Sushant Jain s DTNSim, which was used for the Routing in a delay tolerant network paper. It has been exensively modified.

在节点移动规律无法预知、连通性较差的延迟容忍网络中,针对DTN 网络的Ferr y 节点自定位方案, 能够有效提 高网络中数据信息采集效率。-Unpredictable node movement law, poor connectivity, delay tolerant network, network Ferr y for DTN nodes self-positioning program, can improve the efficiency of the network info

改进路由协议AODV,使之在NS2仿真的稀疏Ad-hoc网路（DTN）中具有更高的数据包投递率，更低的时间延迟。-Improved routing protocols AODV, NS2 simulation Sparse Ad-hoc Network (DTN) has a higher packet delivery ratio, lower latency.

This Project Simulate variety Delay tolerant Network Routing Protocol Such as Spray&Wait,Epidemic, PRoPHET and Broadcast with ns2 that patched with DTN.
