Hi, Thanks for the reply Lioy, Marcello.
I understand that for spanning a node over multiple broadcast domains we need to be more vigilant of the unending flooding of messages. That's something I realised after you pointed out. I wonder, if DTN routing algorithms have some way of doing checks. But there is one more prime issue I am interested in is the proximity of nodes. A<---->B<---->C <--------. . . > A is offering some services to B(service for eg. can be traffic updates/score of a match .A is server and B is client.) Suppose in the above scenario, A and B are in a reachable distance so that they could communicate easily without hassle. To start with a simplistic scenario, what if, there is some C which currently ha no means of communication with any of the Alljoyn nodes(routers) which offer services that C is interested. C also would like to use the services offered by A. B even though it's not offering any services is in the proximity of C and can communicate. 1. *Is there any way we could do this using current framework ? * 2. *Is piggy backing messages from A at B to C an interesting option to consider? Can this approach be added to framework?* I am excited to know your thoughts on this Satya Vasanth Reddy <https://mail.google.com/> Bachelor of Technology (2013-'17) Computer Science and Engineering Indian Institute of Technology , Hyderabad <https://in.linkedin.com/pub/satya-vasanth-reddy-t/83/943/774> On Fri, Sep 30, 2016 at 3:29 AM, Lioy, Marcello <[email protected]> wrote: > That clarifies.
