Accurate and Efficient Wireless Device Fingerprinting Using Channel State Information
Due to the loose authentication requirement between access points (APs) and clients, it is notoriously known that WLANs face long-standing threats such as rogue APs and network freeloading. Take the rogue AP problem as an example, unfortunately encryption alone does not provide authentication. APs need to be equipped with certificates that are trusted by clients ahead of time. This requires eit...
متن کاملConditional Entropy and Location Error in Indoor Localization Using Probabilistic Wi-Fi Fingerprinting
Localization systems are increasingly valuable, but their location estimates are only useful when the uncertainty of the estimate is known. This uncertainty is currently calculated as the location error given a ground truth, which is then used as a static measure in sometimes very different environments. In contrast, we propose the use of the conditional entropy of a posterior probability distr...
متن کاملChannel State Information Fingerprinting Based Indoor Localization: a Deep Learning Approach by
With the fast growing demand of location-based services in indoor environments, indoor positioning based on fingerprinting has attracted a lot of interest due to its high accuracy. In this thesis, we present a novel deep learning based indoor fingerprinting system using Channel State Information (CSI), which is termed DeepFi. Based on three hypotheses on CSI, the DeepFi system architecture incl...
متن کاملModified Fingerprinting Algorithm for Indoor Location
—This paper proposes a modified fingerprinting hybrid location algorithm for homogeneous and heterogeneous indoor environment. The new method is designed based on fingerprinting to improve the location accuracy. It works in two phases: one is offline phase, which opts for the location of reference point by different kind of complex regions. Another one is online phase, which proposes dynamic K...
متن کاملError Estimation for Indoor 802.11 Location Fingerprinting
802.11-based indoor positioning systems have been under research for quite some time now. However, despite the large attention this topic has gained, most of the research focused on the calculation of position estimates. In this paper, we go a step further and investigate how the position error that is inherent to 802.11-based positioning systems can be estimated. Knowing the position error is ...
