Research And Implementation Of Spectrum Monitoring Network And Transmission Protocol Based On Embedded System

The thesis research on the network structure and protocol stack design of wirelesssensor electromagnetic spectrum monitoring network based on the transmissionperformance and networking requirement of the spectrum monitoring management.Firstly, we construct the embedded linux OS platform based on ARM followed by thediscussion of protocol that physical layer and data link layer adopted. Secondly, weanalyses the aspects that would affect the transmission performance in WIFI,WCDMA,TD-SCDMA and design the heterogeneous network combined WIFI in firstlayer with WCDMA and TD-SCDMA in second layer. The network structure meets theflexibility networking requirement in which the sensor node, gateway node andmanagement node can interconnect with different date type. The thesis focused on thetwo application layer protocol designed in accordance with the system operation. Theresult demonstrates that the network structure and protocol we designed is fullycapable to meet the needs of the mass spectrum monitoring data transmission andflexibility networking in electromagnetic spectrum monitoring network.
