Abstract :
In this paper, an analytic framework is devised, based on the principle of maximum entropy (ME), for the performance modelling of wireless 4G cellular networks with bursty multimedia traffic under an efficient buffer threshold-based generalized partial sharing (GPS) traffic handling scheme. Analytical closed-form expressions for the state probabilities have been characterized, subject to appropriate GE-type queueing and delay theoretic constraints and new expressions for the aggregate state and blocking probabilities are determined. Typical numerical examples are included to validate the ME performance metrics against Java-based simulation results and also to study the effect of bursty multiple class traffic upon the performance of the cell
