Android Communication

Question

Let's say i have three android devices, Device A, B and C. Now Device A wants to send a file to C but is too far away. Device A wants to use B to send a file to C. What medium should be used for this idea and why? 1. Wifi 2. Wifi-Direct 3. Hotspot.

Answer 1

I suppose the problem is prettysame as is with the Thaliproject.

So, first you would need to figure out

• how to discover devices,
• how to identify discovered devices, and also
• how to route the data to the identified destination.

I don't think there would be a simple answer on using XYZ for doing all the task, you would actually need to specify your requirements, and then see which technology/technologies would fit to solving the issues.

For example in Thaili with first release the data delivery is handled via insecure-Bluetooth-sockets, while discovery & identification is handled via Wifi-Direct. Later versions will be likely using some other mixtures for tasks.
