Nonclassical traffic modeling and performance analysis of cellularmobile networks with and without channel reservation

摘要

We present a two-moment performance analysis of cellular mobilennetworks with and without channel reservation. Unlike classical analysisnwhere handoff traffic is modeled as Poisson, we characterize handoffntraffic as a general traffic process and represent it using the firstntwo moments of its offered traffic. We empirically show that handoffntraffic is a smooth process under negative exponential channel holdingntimes. We also show how one may determine customer-orientedngrade-of-service parameters such as new-call blocking, handoff callnblocking, and forced termination probability under the two-momentnrepresentation of traffic offered to each cell. We present extensivenresults validating our analysis. We compare the performance of thenproposed two-moment analysis with classical single-moment analysis andnsimulation results. Our simulation employs five different mobilitynmodels. We show that our proposed model outperforms the existingnanalytical method when compared to simulation results employing all fivenmobility models
