Energy Model in an Open Hardware Wireless Sensor Network

Resumen

Energy model and the characterization of the coverage of the link of a wireless sensor network of open hardware are presented. Measurements of energy consumption of the WSN are shown using different power levels of RF transmitter. Characterization as well as telemetry measurements were performed in open countryside on a network of sensors with wireless connectivity using 63mw xbee pro whip antenna modules. Readings are performed in rough topography, warm temperate climate; the data collecting was recorded in summer, sensors modules assumed in the area of geo-position. Established connectivity, bursts of data were sent and returned to the module Coordinator. The testing shows that according the experiment, a distance of 300 meters between nodes is the best option to keep the reliability of the link.
