A positioning service for pervasive objects in dynamic environments

Pervasiveness of electronic devices and networks allows to design ubiquitous services, which use distributed sensors as their extensions. Localization of mobile objects using standard protocols and infrastructures is an open issue. Standard protocols that allow an integrated use of heterogeneous technologies have been defined, but it is necessary to use terminals, which are enabled to exploit a minimal amount of resources, and are equipped with required interfaces for localization and communication. In this work, we aim at extending the positioning service in order to detect and localize different kinds of objects of the everyday life, exploiting cheap and embedded technologies. We describe the design and the prototypal implementation of a layered architecture, that supports the localization of devices, and simple pervasive and ubiquitous objects, which are not enabled to access the positioning infrastructure and to exploit localization services.
