Design Considerations on Implementing an Indoor Moving Objects Management System
نویسندگان
چکیده
In this paper, we present a framework to implement a database management extension for indoor moving objects based on a commercial Object-Relational DBMS. As most people are living in indoor spaces, it is valuable to investigate people’s moving trajectories in indoor space so as to develop indoor location-based services. We first present the general idea of managing indoor moving objects via ORDBMS, as well as the detailed design on the data types and operations. Then, we give the implemental results and a case study is presented.

Indoor - 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 کاملAn Indoor Positioning System Based on Wi-Fi for Energy Management in Smart Buildings
To offer indoor services to occupants in the context of smart buildings, it is necessary to consider information concerning to the identity and location of the occupants. This paper proposes an indoor positioning system (IPS) based on Wi-Fi fingerprint and K-nearest neighbors (KNN) method. The positioning of a mobile device (MD) using Wi-Fi technology involves online and offline phases. In this...
