Mathematical Modeling for Evaluation of Quality of Service Parameters in Next Generation Cellular Wireless Networks

In this paper, a mathematical model has been developed for cellular wireless network with Gamma inter-arrivals and general call holding times. Measurement based studies have shown that Poisson assumption averages out the traffic characteristics to a single parameter (i.e. average rate) which does not represent the real dynamics involved in the process. The actual traffic pattern in the next generation cellular wireless networks is more complex for the presence of multiple services. This work evaluates the QoS parameters from a more pragmatic model for future cellular wireless networks.
