Framework and Transmission Media Test of Embedded Wireless Frequency Spectrum Sensor Network Based on TCP/IP

摘要

Electromagnetic frequency spectrum monitoring is a critical technology guaranteeing full and ordered use of frequency spectrum resources, while the existing monitoring equipment and monitoring methods have been unable to meet the growing mission requirements. Wireless sensor network (WSN), as a feasible mean, is a new type of distributed information system developed by wireless self-organized network technology. Based on TCP/IP, this study mainly explores the framework design and practical construction of embedded frequency spectrum sensor network, discusses embedded ARM hardware platform and Linux operating system platform when constructing wireless frequency spectrum monitoring network, and finally adopts two-layer network model for data transmission according to adaptive network invitation and the minimum transmission rate. Through tests in real system, application layer protocol and network model discussed and designed in this study are able to organize network on their own in a large scale, and transmission rate also can meet the requirement of the large data volume of frequency spectrum monitoring network.
