Yolco:
when I switch off the router for a long time (simulating battery breaks down), it needs some time to add again to the network.
Hmmm, how much time does it need, and how are you judging when it is added again to the network?
Just to make sure I was remembering correctly, I did the following experiment. This is a network with six routers and no end devices (and one coordinator of course). Router1 sends data to Router2 and also to Coord. Router2 sends data to Coord only.
- Powered down Coord and Router2.
- After a few minutes, powered up Router2, leaving Coord off.
- Router2 continues to receive data from Router1, without long delay.
