There are many localization schemes used for the indoor or outdoor applications, such as the GPS, RADAR etc. However, the accuracy of indoor localization scheme is easy to be influenced because of the obstacles and the environment interference. LANDMARC which is proposed by Lionel et al. uses the RFID tags to reduce the influence of the interference. This paper proposes an improved localization scheme, FLEXOR, which divides the localization area into cells to reduce computational overhead and provide two localization modes: region mode and coordinate mode. In the performance evaluations, FLEXOR has been proved to have the advantages of fast localization, flexibility, and it also provides the high localization accuracy as LANDMARC.
