Connecting the Dots: Informing Location-Based Services of Space Usage Rules Hasselt University
Today, a large set of location-based services exists and millions of people use these applications on a daily base. These services are capable of fulfilling and assisting with a variety of tasks, such as fetching points of interest or indicating friends nearby, performing web search requests, which respect the context of the user, or navigating to a destination point. Even though these are very helpful tools, most LBS perform simplistic ...
Location-based services and localization in WiMAX networks Vrije Universiteit Brussel
Wireless communication operators have realized the value and potential to make information services highly personalized. One of the best ways to personalize information services is to enable them to be location based. Today, WiMAX is a promising technology; but despite the quality of service and high speed, WiMAX must have the ability of providing location-based services (LBS) to be widely adopted. Providing LBS requires knowing user's location ...
Privacy through Uncertainty in Location-Based Services Hasselt University
Location-Based Services (LBS) are becoming more prevalent. While there are many benefits, there are also real privacy risks. People are unwilling to give up the benefits - but can we reduce privacy risks without giving up on LBS entirely? This paper explores the possibility of introducing uncertainty into location information when using an LBS, so as to reduce privacy risk while maintaining good quality of service. This paper also explores the ...
Current trends and challenges in location-based services Ghent University
Location-based services (LBS) are a growing area of research. This editorial paper introduces the key research areas within the scientific field of LBS, which consist of positioning, modelling, communication, applications, evaluation, analysis of LBS data, and privacy and ethical issues. After that, 18 original papers are presented, which provide a general picture of recent research activities on LBS, especially related to the research areas of ...

Privacy in Location-Based Services KU Leuven
The Internet has fundamentally changed our society, the way we live, work and express ourselves. Improvements on information and in communication technology have created mobile devices that offer smart mobile services that keep us constantly connected and that deliver digital content. Millions of such mobile service are available today. While being inexpensive in terms of actual money, user data has become the actual currency, rewarding the ...

Fingerprinting Localization in Wireless Networks Based on Received-Signal-Strength Measurements: A Case Study on WiMAX Networks Vrije Universiteit Brussel
This paper considers the problem of fingerprinting localization in wireless networks based on received-signal-strength (RSS) observations. First, the performance of static localization using power maps (PMs) is improved with a new approach called the base-station-strict (BS-strict) methodology, which emphasizes the effect of BS identities in the classical fingerprinting. Second, dynamic motion models with and without road network information are ...
Robust Tracking in Cellular Networks Using HMM Filters and Cell-ID Measurements Vrije Universiteit Brussel
A localization algorithm based on cell identification (Cell-ID) information is proposed. Instead of building the localization decisions only on the serving base station, all the detected Cell-IDs (serving or nonserving) by the mobile station are utilized. The statistical modeling of user motion and the measurements are done via a hidden Markov model (HMM), and the localization decisions are made with maximum a posteriori estimation criterion ...
