Summary:Cognitive radio (CR) is a revolutionary wireless mobile communication technology. Smart users can use the CR technology to sense the surrounding environment, search for available spectrum resources and access spectrum dynamically. Differential frequency hopping (DFH) is known as an effective FH technique for increasing data rate of HF communication system. In this study, the cognitive radio technology was applied in DFH, and a CogDFH network was proposed. This network which is built upon the interference temperature model, IC-colorings and IC-indices of graphs, was applied to the DHF network with easy build, high robustness and low interference. The scenario simulations of both Cognitive-Based DFH Network and traditional DFH were performed. The results indicate that the network performance can be improved by CR.
