Wireless sensor networks have been deployed widely. Sensor networks involve sensor nodes which are very small in size, low in cost, and have a short battery-life. One of the critical wireless sensor network applications is localisation and tracking mobile sensor nodes. ZigBee is a new, emerging technology for low rate, low power, and low range communication networks, which aims to provide long battery life for network devices. In this paper, we propose a decentralised ZigBee-based tracking system to detect and track the location of mobile nodes indoors. End-devices have limited connection capabilities which cause a problem in localisation. End-devices are collaborated in the tracking process in order to reduce the power-consumption for ZigBee networks. The proposed tracking system can be deployed in an area where the density of router nodes is very low. The tracking system is implemented by ZigBee sensor devices, and experiments have been done to evaluate the proposed tracking system based on battery life and communication cost.
