The reason for this implementation is due to the fact that, in the studied plant configuration, the sensors communicate with the PLC (Programmable and Logic Controller) by the cables and pipelines, making any changes in that system, such as changing the layout of it, as well as inconveniences that arise from the nature of the site, such as the vicinity s animals presence that tend to destroy the cables for interconnection of sensors to the PLC. For software development, was used communication polling method via SMAC protocol (Simple Medium Access ControlIEEE 802.15.4 standard) in the CodeWarrior environment to which generated a firmware, loaded into the WSN s transceivers, present in the kit MC13193-EVK, (all items described above are owners of Freescale Semiconductors Inc.). The network monitoring and parameterization used in its application, was developed in LabVIEW software from National Instruments. The results were obtained through the observation of the network s behavior of sensors proposal, focusing on aspects such as: indoor and outdoor quantity of packages received and lost, general aspects of reliability in data transmission, coexistence with other types of wireless networks and power consumption under different operating conditions. The results were considered satisfactory, which showed the software efficiency in this communication system === Este trabalho tem por finalidade desenvolver um software aplicado a um sistema de comunica??o de uma rede de sensores sem fio (RSSF), para monitoramento de vari?veis anal?gicas, digitais e comando de v?lvulas de passagem do fluxo de g?s em unidades de eleva??o artificial de petr?leo e g?s natural do tipo Plunger Lift. A raz?o desta implementa??o deve-se ao fato que, na configura??o da planta estudada, os sensores comunicam-se com o CLP (Controlador L?gico Program?vel) atrav?s de cabos e dutos, dificultando eventuais modifica??es nesse sistema, tais como mudan?a de layout do mesmo, al?m de inconveni?ncias que venham a surgir da pr?pria natureza do local, como a presen?a de animais nas redondezas que tendem a destruir os cabos de interconex?o dos sensores ao CLP. Para o desenvolvimento do software, foi utilizado o m?todo de comunica??o polling, atrav?s do protocolo SMAC (Simple Medium Access Control - padr?o IEEE 802.15.4), no ambiente CodeWarrior, ao qual gerou um firmware, carregado nas placas de monitoramento da RSSF, presentes no kit MC13193-EVK, (todos os itens descritos acima s?o propriet?rios da Freescale Semiconductors Inc.). O monitoramento e parametriza??o da rede utilizou uma aplica??o, desenvolvida no software LabVIEW, da National Instruments. Os resultados foram obtidos atrav?s da observa??o do comportamento da rede de sensores proposta, focando aspectos, tais como: quantidade de pacotes recebidos e perdidos em ambientes externos (Outdoor) e internos (Indoor), aspectos gerais de confiabilidade na transmiss?o dos dados, coexist?ncia entre outros tipos de redes sem fio e consumo de energia sob diferentes condi??es de opera??o. Os resultados obtidos foram considerados satisfat?rios, o que comprovou a efici?ncia do software neste sistema de comunica??o ===
