Object localization using ZigBee network


I would like to implement an object localization system using ZigBee network. Basically, I will have fixed ZigBee routers or stationary nodes that can communicate with a ZigBee mobile device (Tag) to determine the RSSI. In this case, I want to be able determine the RSSI of each router. Will I be able to do this with XBee Series 2? If not, what can I use to achieve this? I’ve attached a diagram for illustration.

Also, I want to be able to track more than one tag or mobile node.

I would suggest using the 802.15.4 protocol for this application instead of the Zigbee based ones.

I am doing similar kind of project and using Xbee pro s2b modules in API mode. I am kind of stuck in getting the RSSI from all the routers attached to Co-ordinator.
