Redes de sensores sem fio aplicadas ao monitoramento de uma malha de aterramento.

Abstract

This work presents a communication protocol designed to be implemented in a wireless sensor network for sensing voltage levels in different points of a grounding mesh. The protocol is based in the IEEE 802.15.4 standard and is responsible to organize the traffic of information between the sensor nodes and the processing central. The protocol also defines a scheme that helps the network to the data read by the sensor nodes to a common time base. A prototype of the wireless sensor network was created to rest the proposed protocol.
