  • Two handoff queuing schemes of Opportunistic Spectrum Access (OSA) system are proposed for non-real-time services. For each scheme, a two-dimensional Markov chain analysis is presented and the blocking probability, force termination probability and bandwidth utilization are obtained. Numerical results show that the handoff queuing schemes can greatly reduce forced termination probability and the bandwidth utilization can be improved by 26% compared to the handoff channel reservation scheme with high blocking probability and low bandwidth utilization. The simulation results are observed to match closely with the numerical analysis.
