Abstract

Dynamic spectrum access (DSA) is important for spectrum management in the future. DSA with prioritization for two types of radio systems are presented through analytical formulation. The DSA with prioritization model is solved numerically using a two-dimensional Markov chain. Grades of service (GoSs) like system airtime and blocking probabilities are considered. The performance of these GoS measures and the effect of the size of the number of frequency channels for DSA with prioritization are evaluated. Numerical results illustrate that the advantages of DSA with prioritization for one type radio system over another type of radio system.
