Distributed spectrum monitoring system based on RSSI optimization algorithm

Electromagnetic spectrum is an indispensable resource. Traditional hand-held spectrum device has many shortcomings, such as high cost of equipment, as data timeliness is poor. We propose to establish a regional electromagnetic spectrum monitoring system. We set up a distributed monitoring node to monitor the electromagnetic environment of the target area in real time. It locates the signal source, and provides the data for the wireless secondary user access spectrum dynamically. The server aggregates the data of monitor node through heterogeneous networks, and creates spectrum database. The system calculates the channel occupancy and frequency occupancy of the target frequency band automatically, and analyzes the occupied area of the target area. Based on the distributed spectrum monitoring system, the RSSI optimization algorithm is used to improve the positioning accuracy of the target area. It improves the immediacy and usability of the monitoring system. It makes the electromagnetic wave become visual. After testing, the system can realize quickly spectrum detection and real-time analysis of the target area. Finally it provides the basis for painting the spectrum map.
