Seamless Pedestrian Positioning and Navigation Using Landmarks

Seamless indoor/outdoor positioning with streamspin

This paper presents the implementation of novel seamless indoor/outdoor positioning service for mobile users. When users are not within GPS range, the service exploits the wifi access point infrastructure for positioning. A central server stores wifi radio maps and map images that are then sent to user terminals based on the mac addresses of nearby access points. The positioning services is ava...

Indoor/Outdoor Detection for Seamless Positioning

Location-based Services are often required to cover indoor and outdoor environment, while indoor/outdoor detection for seamless positioning remains a longstanding challenge for Location-based Services. This paper presents an indoor/outdoor detection based on the variation of signals from multi-base stations. After study previous work, we put forward a new sampling algorithm, and then optimized ...

Seamless Federation of Heterogeneous Service Registries

Web service technology extends the existing web infrastructure by transforming it from a repository of documents to a source of services. As the number of web services increases, the provision of the appropriate service publication and discovery framework is of paramount importance for exploiting the full potential of the web service technology. This paper presents the principles, the functiona...

Augmentation of Low-cost GPS/MEMS INS with UWB Positioning System for Seamless Outdoor/Indoor Positioning
