ABSTRACT
This chapter discusses the terminals, the servers, and the software. The infrastructure consists of the sensor system, the network, the software, the servers, which are the environment for the execution of the services, and the terminals, which are used to provide the location-based services to the users. The infrastructure consists of the sensor system, the network, the software, and the terminals, which are used to provide the location-based services. Applications access the infrastructure to retrieve context information. Sensors are linked to the infrastructure to provide it with their sensor information. Using such an infrastructure allows applications to access context information that has been captured by sensors far away from their position, but requires mobile devices and sensors to be connected to the infrastructure, as all communication takes place through the infrastructure. Context-aware computing relies on an available infrastructure that has a globally accessible data repository.
