Smart Spectrum Handoff for Multimedia over CRN
Hybrid spectrum handoff with minimized delay, increased end user satisfaction, and optimized performance. It utilizes a new queuing model that includes mixed preemptive and non-preemptive resume priority to ensure minimum handoff delay. A novel driven handoff scheme maximizes end-user satisfaction using quality of service and quality of experience metrics. The inventors have shown that the their handoff scheme outperforms the delay-driven reference scheme by about 1 ∼ 3dB under different arrival rate of secondary users.
