Abstract

Seamless positioning is now the key technology to meet the increasing requirements of Location Based Service (LBS). The handoff algorithm plays an important role in the seamless positioning. Current handoff algorithms are mainly based on the Received Signal Strength (RSS), and it is not reliable in complex scenarios. This paper presents a Euclidean distance based handoff algorithm. The proposed handoff algorithm works reliably in complex scenarios. By using the proposed handoff algorithm, Wireless Local Area Network (WLAN) based fingerprint positioning system can be combined with any positioning system. Moreover, a dual-threshold scheme is proposed to solve the ping-pong problem and improve the accuracy of the proposed algorithm. Experiments are carried out to validate the effectiveness of proposed algorithm. The error rate of the handoff decision is only 2.39%.
