Summary:Made available in DSpace on 2016-04-04T18:31:44Z (GMT). No. of bitstreams: 1 Cilene Renata Real.pdf: 2194008 bytes, checksum: 1cc615475d891ef3e2695f71044b36dd (MD5) Previous issue date: 2015-06-25 === Scientific work that shows the signal strength behavior in a Wireless Sensor Network (WSN) in the industrial environment. This dissertation aims to perform collections of Radio Signal Strength Indicator (RSSI), to suggest a method to analyze the signal behavior and to subsidize criteria for decision making, when the signal presents significant instability. The expected benefit is the characterization of this environment, allowing knowledge about the behavior of this type of network, which today, although necessary, is still limited, thus contributing to the development of reliable applications that use this type of network. The results of the signal strength measurements have been analyzed for their stability. === Trabalho cient?fico que demonstra o comportamento da intensidade do sinal em uma Rede de Sensores sem Fio (RSSF) no ambiente industrial. A presente disserta??o tem como objetivo, realizar coletas de Radio Signal Strength Indicator (RSSI), sugerir um m?todo para analisar o comportamento do sinal e subsidiar crit?rios para a tomada de decis?o, quando o sinal apresentar uma instabilidade significativa. O benef?cio esperado ? a caracteriza??o desse ambiente, permitindo o conhecimento sobre o comportamento desse tipo de rede, que, hoje, apesar de necess?rio, ainda ? limitado, contribuindo, assim, para o desenvolvimento de aplica??es confi?veis que utilizem esse tipo de rede. Os resultados das medidas de intensidade de sinal foram analisados quanto ? sua estabilidade.
