Performance Modelling of a Wireless 4G Cell under GPS Scheme

Abstract

A novel analytic framework is devised for the performance modelling of a wireless 4G cell with bursty multiple class traffic flows consisting of Internet protocol (IP) voice calls, streaming media and data packets subject to an efficient medium access control (MAC) protocol with a buffer threshold-based traffic handling generalized partial sharing (GPS) scheme. In this context, an open queueing network model (QNM) is proposed consisting of three interacting multiple class GE-type queueing and delay systems and maximum entropy (ME) joint state probabilities are characterized, subject to appropriate GE-type mean value constraints. Moreover, closed form expressions for the aggregate state and blocking (per class) probabilities are determined. Typical numerical examples are included to validate theME performance metrics against Java-based simulation results and also to study the effect of bursty multiple class traffic flow upon the performance of the wireless 4G cell.
