Location-based services In ubiquitous communication systems

Abstract

There are many approaches and models regarding the localization of a mobile terminal. However, each one of them has both advantages and disadvantages. Nowadays, the challenging issue is not only localization, but tracking as well. In this project, related work will be studied, concerning approaches of modifications and optimizations of current models as well as novel proposals, in order to provide a quality review of them, according to challenging criteria, such as accuracy, latency and efficiency. Furthermore, there is a theoretical proposal of a modification or even a potential merging of the studied related work. Specifically, a theoretical Hidden Markov Model-based model is proposed, modified with a novel map-aware model, to improve accuracy and latency. The development of the proposed scheme is considered to be future work, however, an experimental analysis is conducted to test the viability and efficiency of the map-aware modification.
