Redes de sensores sem fio / redes virtuais de sensores: uma análise literária

Abstract

With the great progress of network technologies, an area has been gradually gaining its space: the Wireless Sensor Networks (WSNs). These networks may be used to receive information about various phenomena, such as forest fires, earthquakes and tsunamis; and to locate objects or people. With so many uses approached for this type of network, and since the common WSNs depend a lot on the application to which they are meant, they had to evolve and, instead of a single network monitoring a single phenomenon, we may have these networks acting in a cooperative way. Moreover, their nodes may be used by several applications at the same time in several Virtual Sensor Networks. This work aims to integrate many others published on the internet, and to facilitate the understanding of this technology.
