Previous issue date: 2015-08-03 / Uma Rede de Sensores sem Fio (RSSF) consiste de dispositivos distribu?dos em uma ?rea com a finalidade de monitorar vari?veis f?sicas, tais como temperatura, press?o, vibra??o, movimento e condi??es ambientais em locais onde as redes cabeadas seriam complicadas ou impratic?veis de serem implementadas, por exemplo, aplica??es industriais de dif?cil acesso, monitoramento e controle de po?os petrol?feros terrestres ou mar?timos, no acompanhamento de extensas ?reas de cultivo agr?rio e animal, entre outros.
Para ser vi?vel, uma RSSF deve possuir requisitos importantes, tais como baixo custo, baixa lat?ncia e, principalmente, baixo consumo de energia. Entretanto, para garantir tais requisitos, essas redes sofrem limita??o de recursos, al?m de, eventualmente, serem utilizadas em ambientes hostis, levando a altas taxas de falhas, tais como roteamentos segmentados, perda de mensagens, reduzindo a efici?ncia podendo chegar, inclusive, a comprometer a rede como um todo.
Este trabalho tem por objetivo apresentar o FTE-LEACH, um protocolo de roteamento energeticamente eficiente e tolerante a falhas, mantendo a efici?ncia na comunica??o e na dissemina??o de dados. Tal protocolo foi desenvolvido baseado no padr?o IEEE 802.15.4 e voltado ?s redes industriais com recursos energ?ticos limitados. / A Wireless Sensor Network (WSN) consists of distributed devices in an area in order to monitor physical variables such as temperature, pressure, vibration, motion and environmental conditions in places where wired networks would be difficult or impractical to implement, for example, industrial applications of difficult access, monitoring and control of oil wells on-shore or off-shore, monitoring of large areas of agricultural and animal farming, among others. To be viable, a WSN should have important requirements such as low cost, low latency, and especially low power consumption. However, to ensure these requirements, these networks suffer from limited resources, and
eventually being used in hostile environments, leading to high failure rates, such as segmented routing, mes
sage loss, reducing efficiency, and compromising the entire network, inclusive. This work aims to present the FTE-LEACH, a fault tolerant and energy efficient routing protocol that maintains efficiency in communication and dissemination of data.This protocol was developed based on the IEEE 802.15.4 standard and suitable for industrial networks with limited energy resources
