Mobility and teletraffic issues in wireless personal communications

Personal communications and next generation wireless networks pose challenging problems in performance modeling and analysis due to type and pattern of source mobility, radio propagation and fading effects, interference environment, reduced cell sizes, call delivery, dynamic resource assignment and heterogeneity of traffic. In this paper, we discuss issues in mobility and teletraffic characterization of mobile sources. We note that the system architecture plays an important role in determining the overall system performance.
