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.
