Abstract :
The location-aware technology and its application are prerequisite to realize the ubiquitous computing. However, another special system for indoor localization is needed in the complicated indoor environment, where the Global Positioning System (GPS) is not available. RFID technology makes the building up of indoor localization system with low cost possible. LANDMARC is an indoor localization system using RFID technology, which introduces the concept of reference tag to reduce the number of deployed RFID readers and provides high possibility to be used in reality, and we can guarantee the accuracy of localization and thus lower the cost of importing system with it. In this paper, we analyze the existing LANDMARC system, solve the potential problems within it and propose a more efficient mechanism to enhance the accuracy of indoor localization
