In this project, we build an energy-aware localization system based on Zigbee radio sensor network. Promising to satisfy an applicationís requirements on positional accuracy, the system tries to minimize its energy consumption. Our method is to adapt the sampling rate to the targetís mobility level. We have created several real testbed deployments and shown that energy saving can be as high as 50%.
