- Abstract
- In order to estimate the user position in indoor space using wireless communication infrastructure, location-DB of access points must be constructed first. The accurate location information of the deployed access points does not exist because the access points have been used not for positioning but for communication. In this paper, a construction method of the location-DB is proposed without previous information about the access point location. The method consists of coarse searching step and fine marking step. In the coarse searching step, the entire APs can be searched and the coarse location information of the APs can be obtained. Then, the fine location-DB can be constructed by artificial marking map matching in the fine marking step. The error analysis is performed for evaluating the performance of the proposed method. Finally, the performance is verified by simulation.
