Power Efficient Indoor/Outdoor Positioning Han- dover

چکیده
This paper presents a novel technique to switch automatically between indoor and outdoor modes in an oncampus positioning system. This system uses Wi-Fi fingerprinting for indoor positioning, and GPS for outdoor positioning, and provides useful information to students about their location, and what surrounds them. The technique described in this paper detects when the user comes in or out of a building and switches the positioning technology automatically. It is also battery conservative, as it switches off the unused radio depending on the users environment. We show that the algorithm performs well by investigating the transition detection probabilities. Keywords— Fingerprinting; Indoor/Outdoor Switch; WiFi/GPS Switch; Environment Transition

BlueDetect: An iBeacon-Enabled Scheme for Accurate and Energy-Efficient Indoor-Outdoor Detection and Seamless Location-Based Service
The location and contextual status (indoor or outdoor) is fundamental and critical information for upper-layer applications, such as activity recognition and location-based services (LBS) for individuals. In addition, optimizations of building management systems (BMS), such as the pre-cooling or heating process of the air-conditioning system according to the human traffic entering or exiting a ...
متن کاملDevelopment of Time-location Weighted Spatial Measures Using Global Positioning System Data
OBJECTIVES Despite increasing availability of global positioning system (GPS), no research has been conducted to analyze GPS data for exposure opportunities associated with time at indoor and outdoor microenvironments. We developed location-based and time-weighted spatial measures that incorporate indoor and outdoor time-location data collected by GPS. METHODS Time-location data were drawn fr...
متن کاملIndoor - A New Data Management Frontier
Much research has been conducted on the management of outdoor moving objects. In contrast, relatively little research has been conducted on indoor moving objects. The indoor setting differs from outdoor settings in important ways, including the following two. First, indoor spaces exhibit complex topologies. They are composed of entities that are unique to indoor settings, e.g., rooms and hallwa...
متن کاملCombination of Indoor and Outdoor Positioning
Indoor and outdoor environments create contradictory conditions for positioning and guidance of machines. While indoor environments are limited in size to rooms and buildings, outdoor positioning capabilities require regional or even global coverage. Secondly, the difficulty of receipting satellite signals indoors has triggered development of high sensitive and AGNSS receivers – with many issue...
