1. Introduction
The demand for accurate positioning for indoor location based services (LBS) is growing rapidly. The GPS technology cannot be easily used for indoor positioning as the direct line of sight obstructed which reduces the positioning accuracy [1,2]. To overcome the challenges of indoor positioning, many techniques have been developed in the past few years. The reported indoor positioning methods fall into two main approaches. In the first approach, wireless signals such as Bluetooth, Zigbee, RFID, Ultra-Wide Band (UWB), Wireless Local Area Network (WLAN) [3] are leveraged for indoor positioning in the second approach inertial sensors are utilized [4]. Two methods are developed for positioning algorithms utilizing wireless signal techniques. In the first method, the distance is estimated from Time of Flight (ToF), Time of Arrival (ToA)/Time Difference of Arrival (TDoA), Angle of Arrival (AoA) or Received signal Strength Indicator (RSSI) [3]. RSSI for ranging is highly dependent on the environment structure and has limited accuracy [5]. Time measurement based method supports high positioning accuracy but it commonly requires extra infrastructure to accurately measure the time difference. This requirement increases the cost of implementation. An infra-structure free solution which utilizes available wireless local area network (WLAN) have also been reported [6]. In this method, it is assumed that each reference point has a unique RF signal strength vector, which is also called fingerprint. The fingerprints of reference points in a building are collected ahead of time and stored in a database. Then, pattern recognition algorithms are used to match the on-line vector with pre-collected fingerprints. This approach is infrastructure-free but labor-intensive [7]. Moreover, this system normally cannot provide a smooth location estimation because it suffers from problems such as similar fingerprints [8], missing value and noisy RSSI value.
