1.DTN研究组，该网站提供了一些代码，有NS2上的实现，也有用java实现的源码。

2.DTN实现的另一个版本，与ONE比较，目前还没用过
code：http://sourceforge.net/projects/dtn/?source=navbar
manul：http://sourceforge.net/projects/dtn/files/?source=navbar
3.NS2下DTN的实现，已在ns-2.33中成功运行，如果有需要可以联系我，CSDN无法在博客里上传压缩包。
3.1 DTNAgent：http://www.spice-center.org/dtn-agent-build/，官网对该模块介绍如下：
The DTN model is implemented as a set of classes in the ns-2 simulator. The model was developed in order to study the deployment of DTN on top of traditional, Internet-based networks and can be useful in experimenting with issues such as: storage space management, custody acceptance and rejection reporting, routing strategies, retransmission timeouts, and bundle fragmentation. The underlying network topology is assumed to be static and, thus, this model is inappropriate for testing routing algorithms in ad-hoc network settings, at least for the time being. Implementation of a full-fledged routing scheme is part of future development plans. The DTN model supports both TCP and UDP convergence layers.
3.2 DTN的Bundle协议：https://wiki.aalto.fi/plugins/viewsource/viewpagesrc.action?pageId=79045880，原版本是在ns-2.35上实现的，为了方便我将其移植到ns-2.33上了。
4.DTN节点上的TCP

5.DTN论文和书
后续有好的资料我将进行更新
