People have many activities and spend a lot of time in indoor spaces such as airports, shopping malls, and office buildings. There is an increasing demand for indoor spatial queries which support indoor location-based services.

To support the general indoor spatial queries, different techniques have been proposed. However, a comprehensive experimental study on these existing techniques is still missing, and we have to further study different indoor spatial queries to facilitate people in different scenarios in reality.

In this thesis, we focus on the following specific works:

  1. Experimental study on existing proposals for indoor spatial queries.
  2. Indoor Keyword-aware Routing Query.
  3. Indoor Temporal-variation aware Routing Query.
  4. Indoor Crowd-aware Routing Query.
