A energy efficient WSN system for limited power source environments

In this work, a Wireless Sensor Networks (WSN) is analyzed and implemented to control a instrumented process in environments with limited power source. Present propose is based on IEEE 802.15.4 standard, using Zigbee and Modbus protocols. A simplified and robust system architecture is presented, emphasizing the control subsystem of charge and discharge, using solar panels, as well as software optimized for task of network controlling and sensing, both characteristics which that a reduced consumption of energy. These characteristics were proved by energetic efficiency tests and a system study that will be automated to define a rate optimal operation.
