Context-aware modelling of continuous location-dependent queries in indoor environments

A PostgreSQL extension for continuous path and range queries in indoor mobile environments

Continuous location-dependent queries are key elements for the development of locationbased and context-aware services. While most work on location-dependent query processing has been mainly oriented towards outdoor environments, this paper develops an approach for the continuous processing of location-dependent queries over indoor moving objects. A prototype for handling those queries has been...

COST Action IC0903: Knowledge Discovery from Moving Objects (MOVE) CONTEXT-AWARE PROCESSING OF CONTINUOUS LOCATION-DEPENDENT QUERIES IN INDOOR ENVIRONMENTS

A Mobile Agents Based Architecture for the Distributed Processing of Continuous Location Queries in a Wireless Environment: Performance Evaluation

With the current advances of mobile computing technology, we are witnessing an explosion in the development of applications that provide mobile users with a wide range of services. Of special interest are those applications that exploit the particular features of mobile environments to provide the user with context-aware information. In particular, we focus on location-dependent queries, which ...

Spatial Models for Indoor Context-Aware Navigation Systems: A Survey

This paper surveys the multitude of indoor spatial models developed for many fields of study ranging from mobile robot mapping to indoor location-based services (LBS) and most recently to context-aware navigation services applied to indoor environments. Recently, several studies have been presented to evaluate spatial models in the context of mobile robot localisation and mapping [12], [74] as ...

Continuous Query Processing of Spatio-temporal Data Streams in PLACE

The tremendous increase in the use of cellular phones, GPS-like devices, and RFIDs results in highly dynamic environments where objects as well as queries are continuously moving. In this paper, we present a continuous query processor designed specifically for highly dynamic environments (e.g., location-aware environments). We implemented the proposed continuous query processor inside the PLACE...
