Abstract

Spectrum leasing has made more efficient utilization for the limited spectrum resource. While increasing the spectrum utilization, spectrum leasing also brings in some problem. Spectrum switch in the leasing process not only introduces in additional system overhead, but also decreases the secondary user´s Qos. In this paper, we model the wireless system as a M/G/1 queue with preemptive priority, propose a new channel parameter to analyze the switch performance. Algorithms are suggested to reduce system overhead and to improve secondary user´s Qos based on the new parameter.
