Overview of positioning technologies from fitness-to-purpose point of view

Abstract

Abstract-Even though Location Based Services (LBSs) are being more and more widely-used and this shows a promising future, there are still many challenges to deal with, such as privacy, reliability, accuracy, cost of service, power consumption and availability. There is still no single low-cost positioning technology which provides position of its users seamlessly indoors and outdoors with an acceptable level of accuracy and low power consumption. For this reason, fitness of positioning service to the purpose of LBS application is an important parameter to be considered when choosing the most suitable positioning technology for an LBS. This should be done for any LBS application, since each application may need different requirements. Some location-based applications, such as locationbased advertisements or Location-Based Social Networking (LBSN), do not need very accurate positioning input data, while for some others, e.g. navigation and tracking services, highlyaccurate positioning is essential. This paper evaluates different positioning technologies from fitness-to-purpose point of view for two different applications, public transport information and family/friend tracking.

Indoor positioning technology assessment using analytic hierarchy process for pedestrian navigation services

“…According to a user-survey [23], [24] the most important factors to evaluate quality of positioning service, from users' point of view, are accuracy, availability and coverage, cost, power consumption and privacy. Therefore, this paper considers the same set of parameters to compare and evaluates the positioning technologies from the users' point of view.…”

“…For example, Taking the accuracy against availability in the first line, the 1/3 means that the value 1 was given to accuracy and 3 to availability, meaning that availability is 3 times more important for the user than accuracy. The study uses as expert opinion the discussion among the authors and all the tables considered are provided in [25] [23]. The second approach is to use the survey's results [24] to fill out the table.…”

“…The criteria pairwise comparison matrix is mainly based on expert and also LBS users' opinion [23], [24]. However the result of analysis shows more suitability of BLE and WLAN for indoor positioning of pedestrians, very low priority value of all technologies shows that stand-alone positioning technologies may not be a good answer for pedestrian navigation applications.…”

Adaptive real-time dual-mode filter design for seamless pedestrian navigation

“…As a part of the Marie Curie, Multi-Pos project, previous studies presented in [12], [13], [14] analyse the positioning technologies. On this basis, three absolute positioning technologies were selected.…”

The non-technical challenges of Location Based Services markets: Are the users' concerns being ignored?

“…However this growth has faced several challenges and obstacles, including the availability of accurate positioning technologies especially for indoor use [6][7], cost of the service, location privacy issues [8], high power consumption [9], and the user interface of the apps. Some of these challenges are not directly linked to the technology; such "non-technical" challenges, requirements and issues seem to be easier to handle or solved and having a better understanding of them can help the policy makers, manufacturers, service providers and developers to take actions on them and help the LBS markets to grow with a higher growth rate, attracting more users.…”
