Epidemic routing
by Harsha Chenji 21 Mar '11

21 Mar '11

Hello all, I was trying to get some epidemic routing working using 0.4.4. However, I always see in the logs that the bundles expire, irrespective of when they were sent. Is there any config parameter that controls the epidemic routing timeout? Has there been any bugfixes w.r.t this in version 0.6? Harsha

API for custody transfer
by Harsha Chenji 02 Mar '11

02 Mar '11

Hello all, Does anyone have a sample DTN app which handles custody transfer? I looked though the source code, but all I see w.r.t custody transfer is in the storage section of the code. Just like b.setPriority, is there a function like b.requestCustodyTransfer? Thanks, Harsha
