Geometric Methods of Information Storage and Retrieval in Sensor Networks

Sensor networks collect data from their environment. Locations of the sensors are important attributes of that information and provide a context to understand, and use sensor data. In this chapter, we will discuss geometric ideas to organize sensor data using their locations. We will consider distributed methods for managing queries about isolated events, queries about mobile objects, and queries for general signal fields. Location based methods often operate on simple geometric domains, and we will discuss how they can be adapted to networks with complex shapes.
