The requirements for process instrumentation, combined with the advances in wireless communications and electronics allowed the design of wireless sensor networks (WSNs). The technology applied to these sensors and communication networks has enabled the evolution of these systems has been called a smart sensor networks. In this case, not only collect sensor data, but also perform local processing, and may also act in the system, and subsequently, if necessary perform transmission. These smart sensor networks allows a more effective monitoring system, fault detection, and others, thus improving the reliability and system maintenance [2, 3, 6]. |
