Bean: uma plataforma computacional para rede de sensores sem fio

Abstract

Wireless sensor networks are networks of large quantities of compact micro-sensors with wireless communication capability, called sensor nodes. Emerging applications of data gathering range from the environmental to the military. The objective of this work is to project a computer platform, called BEAN (Brazilian Energy-Efficient Architectural Node), that includes software and hardware components, which will be a prototype device for wireless sensor networks.Architectural challenges are posed for designers such as computational power, energy consumption, energy sources, communication channels and sensing capabilities. In our knowledge, BEAN is the first sensor node that allowmeasuring the power consumption of each component and it is the first sensor node prototype designed in Brazil.
