Implementation of radio tomographic imaging based localisation using a 6LoWPAN wireless sensor network
Mobile localisation has numerous uses for logistics, health, sport and social networking applications. Current wireless localisation systems typically require the use of tracking devices to be worn or implanted. The use of tracking devices can hinder the types applications that can be used. Wireless localisation use wireless channel propagation characteristics, such as RF receive signal strength to localise a user's position, which requires the use of complex radio hardware. We developed a wireless tracking system using radio tomographic imaging to track people without wearing a mobile tracking device. We evaluated our wireless localisation network with users in an indoor environment. Our localisation network used the 6LoWPAN wireless communications protocol.
