Optimal Spectrum Leasing with the Constraints of User Admission Rate and Quality of Service

This paper study the optimal spectrum leasing problem with constrains of secondary user admission rate and quality of service from the view of secondary network operators. We model a secondary network as a dynamical data package transportation system, in which data transmission arrives according to a Poisson distribution. An analytical approach is proposed to deduce the upper and lower bounds of the optimal amount of spectrum. With the bounds, the approximate optimum is computed.
