在theONE的邮件列表里看到有人谈到E-DROP，好像没有听说过，马上把文章下下来扫了一下。Oh my gaga, 才两页。英文很不通顺，因为是几个马来人写的。文章列举了很多当前的DROP策略，最后才介绍自己的Efficient-Drop。其实很简单，只不过是把消息从大到小排序，接到新的消息时找到缓冲区中比当前消息大的消息。 很搞笑。 阅读全文

摘要：
The core idea of MaxProp (from wikipedia):To obtain these estimated path likelihoods, each node maintains a vector of size n − 1 (where n is the number of nodes in the network) consisting of the likelihood the node has of encountering each of the other nodes in the network. Each of the n − 1 elem... 阅读全文

摘要：
If you want to compose your own routing module, you have to derive a new class from the ActiveRouter class and rewrite the update() method and probably the replicate() method too. In this article, we look into these two methods. Let's take the DirectDeliveryRouter for an example. The following s 阅读全文

运行ONE：one.sh[-bruncount][conf-files]-b 表示以批处理方式运行，其后必须指定运行的次数，或者运行次数的范围，如one.sh-b3one.sh-b2:4conf-files表示配置文件路径，可以有一个或多个，后面的配置将覆盖前面的配置。关于ONE的配置文件：ONE的配置文件是包含键值对的普通文本文件， 其基本格式为：Namespace.key=value名字空间(Namespace)以大写字母开头，名字空间与键名都以CamelCase的方式命名，并且大小写敏感。通常名字空间定义了配置属性起作用的范围。通常（并不是所有情况），名字空间就是属性所起作用的类的名字。 阅读全文
