Performance analysis of network attack based on continuous time Markov Chain in dynamic spectrum access networks

Dynamic Spectrum Access technology is implemented to help making use of the limited spectrum sources in wireless communication system due to its unique characteristics. However, some threats to this special network were noted with the same reasons. The Primary User Emulation Attack, for example, is a classic issue in Dynamic Spectrum Access networks. In this paper, a continuous Markov Chain Model is used to depict the behavior of dynamic spectrum access with network attack, analyze the characteristics of this network and discuss the performance changes under malicious user's influence with different parameters. The results verify that the modeling and analysis are valid.
