XBee & XBee Gateway

I have 4 xbee s2c and I want to implent a star network in which 1 will be coordinator and other 3 will be routers connected with sensors like temperature, pir, gas along with arduino.
once coding has done using Arduinos all will start transmitting their respected values to coordinator. Now my question is that ‘is dat enough to code the Arduino in receiver side to receive all data as u said csma-ca is already enabled…?’
please help me in this issue.

please give configuration details for the above mentioned network.
regarding CH,DH,DL,AR, etc which are needed to this project.
I want to do in API mode.

All you need to do is enable API mode (ATAP1) on all nodes, then set the CE to 1 (Coordinator Enable) on the coordinator. The routers will join your coordinator automatically.

On your Arduous, make sure you use the proper sample apps. Most of the Arduous codes you will find will require the XBee to be in API mode (AP1).
