A positioning algorithm in the Internet of Things

Location-based service is one of the vital services in the Internet of Things (IoT) which merge many kinds of technologies, like Zigbee, Internet, Infrared, Bluetooth, 3G, GPRS (General Packet Radio Service), Wi-Fi, etc... Along with rapidly growing IoT, applications from personal electronics to industrial machines and sensors are getting wirelessly connected to the Internet. One of the problems is that these devices usually come with many different hardware solutions. In the art of wireless indoor positioning, a lot of research works have been done, however almost these have not addressed to this presence of hardware heterogeneity yet. This paper proposes a new positioning algorithm which is independent of hardware configurations without offline stage. By using mathematical formulation analysis, we demonstrate its advantages than the other techniques.
