Abstract :
This paper shows IEEE 802.15.4a CSS-based localization system for wireless sensor networks. IEEE 802.15.4a CSS technology can provide high accurate ranging functionality to a sensor node. However, as it measures a distance based on time-of-flight (TOF) of RF signal, the system needs well designed ranging and report protocol. In this paper we show our ranging protocol and location calculation server architecture.
