A Mixed Traffic Model for Performance Evaluation of Wireless Networks

In contemporary and future mobile communication networks, variable services with different characteristics need to be served simultaneously. This paper proposes a novel mathematical model for the analysis of such cases based on a two-dimensional Markov approach. This model comprises higher order resource allocation and resource sharing with no packet traffic pre-emption priority and no buffers. The state probabilities of the model have been mathematically derived and can be used as a basis for the evaluation of performance metrics of modern high speed mobile networks supporting two different service classes. Based on the model developed the blocking probabilities of two resource allocation strategies are evaluated for two simultaneous services of different characteristics.
