3 to 1 star network using xbee s2c

i have configured xbee(s2c) in 3 to 1 star network topology.
one as cordinator and other 3 as routers.
all xbees are connected to arduino uno.
routers are connected to sensors like PH sensor, gas sensor and DHT11 sensors.
coordinator have to receive the sensed information through xbees2c

can someone please help me in coding routers and coordinator xbee …
thank you very much

That is nothing more than using API mode on all nodes (ATAP1) and setting CE on the Coordinator to 1. The rest is done in your Arduino.
