Abstracts 
Um abstract (resumo) é um breve resumo de um artigo de pesquisa, tese, revisão, conferência, proceeding ou qualquer análise aprofundada sobre um determinado assunto ou disciplina, e é frequentemente usado para ajudar o leitor a tomar ciência rapidamente do propósito do artigo. Quando utilizado, um resumo sempre aparece no início de um manuscrito, que actua como o ponto de entrada para qualquer artigo científico ou pedido de patente dado.

A critical aspect of applications with wireless sensor networks is network lifetime. Battery-powered sensors are usable as long as they can communicate captured data to a processing node. Sensing and communications consume energy, therefore judicious power management and scheduling can effectively extend the operational time. One important class of wireless sensor applications of deployment of large number of sensors in an area for environmental monitoring. The data collected by the sensors is sent to a central node for processing. In this paper we propose an efficient method to achieve energy savings by organizing the sensor nodes into a maximum number of disjoint dominating sets (DDS) which are activated successively. Only the sensors from the active set are responsible for monitoring the target area and for disseminating the collected data. All other nodes are into a sleep mode, characterized by a low energy consumption. We define the maximum disjoint dominating sets problem and we design a heuristic that computes the sets. Theoretical analysis and performance evaluation results are presented to verify our approach.

CONCLUSÃO 
http://encyclopedia.thefreedictionary.com/Disjoint+sets
Disjoint sets 
In mathematics, two sets are said to be disjoint if they have no element in common. For example, {1, 2, 3} and {4, 5, 6} are disjoint sets.[1]
