Application of Wireless Sensor Networks in Offshore Electromagnetic Spectrum Monitoring Scenarios

Abstract

For the vast sea area, the data of offshore electromagnetic spectrum monitoring is very scarce, and it is still in a relatively blank stage. The main reason is that the offshore electromagnetic spectrum monitoring system is affected by waves, currents, tides and winds, and will undulate, roll and longitudinal. Shaking, three-dimensional movement along the route, the complexity and instability of the marine environment, the offshore electromagnetic spectrum monitoring has been greatly hindered, the monitoring data is fluctuating, accurate and low, and the real-time performance is poor. The traditional electromagnetic spectrum monitoring method can only collect spectral data of discrete points, which is difficult to apply to analyzing spatial spectrum distribution. The system applies the wireless sensor network to the offshore electromagnetic spectrum monitoring, and monitors the antenna attitude (course angle, pitch angle, roll angle), latitude and longitude, node movement speed, parameters such as wind speed, wind direction, an effective way of dealing with complex sea environment, guarantee the stability of the monitoring system in offshore electromagnetic spectrum monitoring.
