  The issue of mobility is important in wireless network because internet
connectivity can only be effective if it's available during the movement of
node. To enhance mobility, wireless access systems are designed such as IEEE
802.16e to operate on the move without any disruption of services. In this
paper we are analyzing the impact of mobility on the QoS parameters
(Throughput, Average Jitter and Average end to end Delay) of a mobile WiMAX
network (IEEE 802.16e) with CBR application.
