Abstract :
This paper studies a Navigation Marks Remote Monitoring and Control System (NMRMCS) based on Wireless Sensor Network (WSN) and Differential Global Positioning System (DGPS). We designed NMRMCS installed in mountain area using WSN and DGPS to increase the positioning precision of navigation marks. We tested communicating distance of nodes by measuring the signal strength both in open region and wooden region, and record the number of flashing LED on ARM board with CC2420 chip, and tested relative parameters in some fixed points using Received Signal Strength Indication (RSSI) provided by highly integrated single-chip CC2420 with a method of least square curve fitting. The tested results show that the mean positioning error of Navigation Marks is less 2.5 meters, are of less positioning error than traditional NMRMCS. We select low power consumption ZigBee protocol based on IEEE 802.15.4 and use low energy-consumption RSSI position algorithm to reduce energy-consumption of NMRMCS.
