That clarifies. That is a feature we have talked about, but you need to be careful because right now About uses sessionless signals, which are built upon link broadcast, so the only way another router wouldn’t see it is if it were on another network. You could add a feature that allows the router to recognize that it is spanning two broadcast domains and can be configured to forward. The risk in that case is that you could end up with forwarding loops if there are two routers spanning the same two networks, or more likely have three broadcast links that are bridged “together”.
I would try and come up with a system design of how you see the messaging working. One you have I would be happy to set up an ad-hoc technical meeting where you would present your design and solicit feedback.

I am trying to start with adding the ability for the About Messages to be discovered via multi-hop. I want to explore the possibility where 2 Alljoyn routers which are not connected directly but through a sequence of Alljoyn routers to be aware of the services they are offering. By achieving this, I can then try to exchange any message with a router that is not directly linked and thereby making the framework suitable for multi hop communication which could then be used to develop applications for vehicular networks. Please let me know if I should provide any more clarification. Forgive me if I am wrong at any point. Thanks again for your time.

I have the Alljoyn framework built in my linux system. My goal, roughly put is to provide an additional functionality i.e.. to add routing functionality at upper layers to the existing the framework.The motivation is finding out the possibility of multi-hop communication using Alljoyn framework. I have gone through the documentation thoroughly and came with the following idea. Adding a new Service and building applications on top of it. Since the new functionality is added at the framework level, future applications can use API abstraction of this feature. We are yet to decide the what message passing algorithm to deploy. I would like to know : 1. If one could extend the services locally. If yes could you provide me with any resources on how to start writing a new service? 2. Do you suggest any alternative approach ? I'm a newbie to Alljoyn framework development and please correct me if I am wrong at some point in my understanding. Also, I would love to here suggestions from experienced developers. Hoping to hear from you. Thank you so much for your time in advance.
