Actually I want to implement XMesh protocol with XBee Series 2 modules.
I am implementing this protocol with 1 coordinator, 2 routers and 2 end devices.
According to this protocol, an end device should select its parent based on linkcost(linkcost = 1/(linkquality)).
This linkquality is measured by sending some messages(expected messages) to the 2 routers from 2 end devices. From the transmit status response I can count received messages using API mode arduino XBee library
(linkquality=(received messages)/(expected messages)).
These end devices each should select the one parent node among two routers.
But the problem here is XBee Series 2 modules are already having inbuilt protocol which is forming adhoc network on the fly. End devices are also choosing parent based on the whichever router provides best network coverage on the spot.
So how can i force end devices to select a particular router as its parent based on the minimum linkcost (i explained it above) using API mode (I am using Arduino XBee library) ?
Below is my network diagram..
