Abstract:

In this paper, we consider the optimal problem of channels sharing with het- erogeneous traffic (real-time service and non-real-time service) to reduce the data conflict probability of users. Moreover, a multi-dimensional Markov chain model is developed to analyze the performance of the proposed scheme. Meanwhile, performance metrics are de- rived. Numerical results show that the proposed scheme can effectively reduce the forced termination probability, blocking probability and spectrum utilization
