Operating Xbee S2 module for 6 months form Battery

Hi Experts,
I am new to Xbee. I am working on lawn monitoring project. I need to measure the sensor data every 5 minutes. I am using Xbee S2 module and it should work in cyclic sleep mode.
The device need to operate for about 6 months with single battery.

Could you please help me to choosing the battery and do i need to design other supporting circutery?

Please help me get the solution for this.

Thanks for the support in advance.
