Analysis on Communication Performance for Secondary Users Classified in Cognitive Radio Networks
Cognitive Radio Networks is an effective technology and a hot research direction which can solve the problem of deficient resource and revolutionize utilization.In order to enhance the communication efficiency,secondary users are classified by some strategy.We exploit the queuing theory model to research on the communication performance of secondary users,considering primary user as the first grade user and secondary users as other grades users.The research results indicate that the users which have lower priority level are more sensitive than those have higher priority level when primary user appears.
