Smart Spaces: Indoor Wireless Location Management System

Determining the location of objects or people in a smart space is one of the prerequisites enabling smart applications. The ideal location system makes use of existing infrastructure such as wireless LAN or cellular communication systems. However, in indoor environment typical wireless LAN systems do not provide sufficient accuracy for many smart applications and such as WLAN based location system needs to be enhanced. This paper involves proposal of a heterogeneous location system based on a combination of IEEE 802.11 WLAN and a sensor network based ultra wideband radar system. The proposed system provides greater accuracy than other proposed systems and provides the added advantage that the sensor network can be utilized for other ubiquitous computing applications.
