Research on Intelligent Frequency Selection Technology for AD HOC Networks Based on Cognitive Radio
The traditional radio design uses a high-speed frequency hopping system to cope with complex electromagnetic environments,but the flexibility of this system is poor,and the actual communication effect and anti-interference ability are not as expected.In response to this situa-tion,a MIX link transmission mechanism solution combining traditional frequency hopping and intelligent frequency selection hopping is proposed.Design intelligent frequency selection tech-nology based on cognitive radio to ensure that network node devices always operate under the current optimal channel conditions,achieving highly reliable communication at any time and place,and effectively utilizing the spectrum.We have analyzed and studied key technologies such as network-based rapid recognition of electromagnetic environments,local spectrum sens-ing,active waveform sensing,and network frequency resource planning for adaptive frequency selection and mutual interference resolution.
