communication between Xbee( API mode)

hello … in my project, I need to establish communication between xbee 3 A, B and C … “A” is mobile on a geographical area as this area is divided into several zones and each sub area is implemented by a xbee B (B0, B1, B2 ….). the xbee C will be in a control office … The work required here is to configure xbee such that A is a transmitter that will connect to one of xbee B, it must inform the office (xbee C) A is in its area …
so i m going to configure A as an end-device, B as a router and C as a coordinator… but is it possible with two Xbee Pro serie 1 and one xbee serie 2 ?? because as i know all the Xbee should be the same serie to be able to communicate with each others…

No. They all would need to be XBee ZB (S2) modules or XBee DM 2.4 modules.
