I need to create a wireless network with high expactations to redundancy and security, making my choise fall on a mesh type network. Between the nodes I should be able to transfer video or at least still images within 5-10 seconds or so to a central, communication on 868MHz without worrying about battery time since it is going to be powered with transformed mains power.
I haven't worked with mesh networks before, so I have started reading up on existing protocols and architectures, but if someone have any suggestions to what architectures I could try to use I would be very grateful.
EDIT: And how would I go forth to implement an open protocol on a microcontroller? Are there libraries I can use that is available for the general public?
