Abstract :
In this paper, we provide a new perspective for analyzing spectrum occupancy by introduced an M/M/l queueing model to generate accurate temporal and frequency behavior of various wireless transmissions. Our proposed research builds upon existing concepts in the open literature in order to develop a more accurate time-varying spectrum occupancy model. This model can be employed by wireless researchers for evaluating new wireless communication and networking algorithms and techniques designed to perform dynamic spectrum access (DSA). Using statistical characteristics extracted from actual radio frequency measurements, first- and second-order parameters are employed in a statistical spectrum occupancy model based on a combination of several different probability density functions (PDFs) defining various features of a specific spectrum band with several concurrent transmissions. To assess the accuracy of the model, the output characteristics of the proposed spectrum occupancy model are compared with real-time radio frequency measurements in the paging and ISM bands.
