Continuous location-dependent queries are key elements for the development of location-based and context aware services. While most works on location-dependent query processing have 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 developed as an extension for the open source DBMS PostgreSQL. Several algorithms for the continuous processing of path searches and range queries applied to both static and moving objects are performed on top of a hierarchical and context-dependent data model. Experimental results have been conducted to report our findings.
