Effect of mobility on QoS provisioning in wireless communication networks

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.
