Am working on Cooperative Caching scheme in Disruption Tolerant Networks.

1. In ONE simulator all the nodes have a packet head which is colored i.e blue and red.Blue packets refer to the number of messages a node has. Then what does Red packets( heads ) mean?

2. Is it possible dynamically to change the properties of a node ? ( what i mean is i have to change the node's routing and range, whenever that node moves out of some predefined range)

3. How to find the number of redundant copies of a message in the network?

When i followed different people, everyone end up with some different answers with which i couldn't come to a conclusion.Since am new to ONE can anyone help me .
