- Abstract:
- In order to guarantee the different service requirements of users, implementing differentiated services for different services and realizing spectrum switching management is one of the main problems that need to be solved urgently in communication systems. The traditional method to study switching problems is Markov modeling, and the Markov model has the characteristics of no memory, and The problem of state space explosion is easy to occur, which makes the research on spectrum switching strategies mostly stay in single-service OFDMA systems. Applying colored Petri nets (colored petri nets, CPN) to develop spectrum switching strategies suitable for multi-service OFDMA systems, established four kinds of The CPN model of the spectrum switching strategy for switching users and the transmission performance of new users. The simulation results show that CPN can overcome the limitations of the Markov model and facilitate the analysis of complex systems, especially the spectrum switching strategies of multi-service systems whose arrival law obeys multiple mathematical distributions .
