Requisitos básicos para a implementação de uma rede de sensores sem fio

Abstract

Wireless sensor networks were created to track an environment or an object and to perform some operation based on the data or to report them to be treated or examined. These networks consist in the use of a large quantity of compact and autonomous devices called sensor nodes, which have the capacity to communicate among themselves. They are applied in many situations of daily life, such as medical, military, commercial, environmental and agricultural applications. In this context, the goal of this work is to define the type of sensor and operating system to be used in a project, which means to process the data obtained from farm machinery equipped by sensors, to track the efficiency of the machine while at work. To do this, a comprehensive review of literature on this recent and expanding subject is presented. This work also describes the stages of hardware and operating system definition, the technologies found and the advantages and disadvantages of each item within its scope.
