This is regarding Epidemic routing and receiving bundles. Using dtntrigger for example, one can receive the bundle targeted to a particular target node.  I.e. When the bundle arrives at the target node, the target node has an immediate knowledge of it (using payload, eid) via script.

Consider the scenario where epidemic routing is used, and an intermediate node receives the bundle meant for a target node. Dtntrigger does not work in this case. My question is, how do I know that intermediate node has received a bundle (programmatically)? DTN daemon has this knowledge of received bundles by the intermediate node but, if an application running on this intermediate node wishes to know that some (external) bundle has been received, how would it know that. It is received into the 'bundles' directory, but I would like something like DTNTrigger for the intermediate node' knowledge! How can I achieve this?

This approach will be very helpful in my aerial application.

Thank you!
