This paper attempts to present current state in the area of user localization in cellular networks and shows custom solution for positioning using pocket computer and fingerprint method also known as fingerprinting. It operates in Global System for Mobile communications (GSM) network, although fingerprinting is also applicable in other wireless networks,(More)
The paper deals with performance evaluation of the indoor positioning solution based on utilization of IEEE 802.11 network and fingerprinting method. It is called WifiLOC and it is implemented as a mobile-assisted positioning system. The architecture of the system is presented. WifiLOC is based on the fingerprinting method, which utilizes signal strength(More)
In recent times smart devices have attracted a large number of users. Since many of these devices allow position estimation using Global Navigation Satellite Systems (GNSS) signals, a large number of location-based applications and services have emerged, especially in transport systems. However GNSS signals are affected by the environment and are not always(More)
In this paper an optimization of the Rank Based Fingerprinting (RBF) algorithm using the Kalman filter will be introduced. In our previous papers it was shown that RBF localization algorithm seems to be more immune and accurate compared to traditional deterministic fingerprinting algorithms. We still decided to improve accuracy of the algorithm in dynamic(More)
In this paper, we deal with the improvement of the positioning accuracy of distance vector (DV)-based positioning algorithms, which use angular information DVangle of arrival (AoA). This algorithm belongs to an adhoc positioning system. We focus on the improvement of the algorithm and its enhanced version is presented. The angular information of particular(More)
In this paper the impact of the Access Points (APs) removal on localization accuracy of Rank Based Fingerprinting (RBF) will be investigated using simulations. The RBF algorithm was previously proposed by the authors and it seems to improve performance of the traditional fingerprinting algorithms and reduce impact of the device change on the accuracy of the(More)
