Abstract

A salient feature of wireless networks is the ability to support roaming. However, user mobility has a profound effect on QoS provisioning. A queueing model which forms the basis for analytically evaluating the performance characteristics of a generic radio cell is proposed. The effect of mobility on (i) degradation in utilization and (ii) excess capacity requirement when the mobile user´s prescribed QoS requirements are maintained is examined. Numerical results pertaining to homogeneous traffic are presented and discussed
