Sensors, Actuators and Communicators When Building a Ubiquitous Computing System

Ubiquitous computing systems are characterized by a collection of devices working together autonomically. Due to the fact that these systems are composed by a high number of devices, several problems arise. These problems range from management, compatibility to economic costs. In this paper some essential characteristics of sensors and actuators are proposed in order to allow them to be included in a ubiquitous computing system. It is also presented a way to build ubiquitous systems by integration of several independent systems, creating one system with new features that could not be found in the original ubiquitous systems.
