how i can transmit the data from coordinator to end device through router

Using the xbee series2 (coordinator,router,end device) these are configured in within same network.but i did’t get how to transmit data from coordinator to end device through router.protocol(zigbee).

You simply set the Coordinators DL and DH to match the SL and Sh of the End device. Providing you have set the SP times to match on the Router and End device, when the data is sent from the Coordinator, the end device will poll the parent for data when it wakes up.
