This paper presents an improvement in deterministic WLAN location determination system using triangulation method. It is a client-based approach which the online location estimation phase, K possible estimates are produced, location estimate is computed as the midpoint of all possible coordinates. The results show that locations with large estimation errors can be drastically reduced thus improvement in prediction error compared with traditional methods.
