Problem With Router Discovery

[ataradov]

The text quite literally explains what you need to do - receive frames from the routers fro some time, record the LQI values.

The way I would approach this is though local broadcasts of the LwMesh. They are a very powerful tool. Make all the routers broadcast their ID via a local broadcast. ED will wake up (if sleep is desired), listen for some time to receive IDs from all the routers, and pick the one with a strongest signal. ED then will send this frame to that router directly. The router routes the frame as usual to the C.

This way you eliminate the need to rebuild the routing tables on the ED.

i would like to use this scenario.. How can i check the signal strength at End Device side and pick the strongest?

A similar option: have the ED broadcast its ID when it is moving. Routers record signal strength from ED and send router address and signal strength to coordinator. Coordinator looks at signal strengths of all routers that rx'd the broadcast and determines location of ED.
