Most previous localization and tracking systems in wireless sensor networks are based on RF signals, ultrasounds, and UWB. However, systems using RF signals suffer accuracy fluctuations and systems using ultrasound or UWB need extra hardware. In our paper, we propose to utilize light, an easily accessible and pervasive resource in our daily life, and(More)
Diverse types of networks function properly in our daily life nowadays. However, information transmitted in these networks has to follow different protocols with distinct devices. In this demo, we have implemented a heterogeneous wireless network testbed – the Universal Sound to connect wireless sensor network, broadcast FM radio network and GSM network.(More)
