Estado da arte de rede de sensores sem fio sob Padrão IEEE 802.15.4.

Abstract

In the past decades, there have been great technological advances in the areas of Microelectronics and Wireless Communication. These advances have resulted in the development and improvement of wireless sensor networks (WSNs). The WSNs are widely applied in various sectors of society. It is possible to group small electronic devices with capacity for sensing and data processing and to put them together to work on monitoring of specific events. In agricultural domain, the WSNs support precision agriculture, reducing waste and increasing production by monitoring the soil moisture and weather conditions. Different standards were created for the definition and regularization of WSNs. One of these standards is the IEEE 802.15.4, which is used by ZigBee technology. In this document, it is purpose a theoretical analysis about WSNs.
