Executive Summary

In this paper, the authors first propose a call admission control algorithm for IEEE 802.16e mobile WiMAX system. They then design the handover mechanism according to the general handover procedure specified by the IEEE 802.16e-2005 standard. Performance evaluations via simulations are conducted to compare the system performance for the network with or without handover procedures employed. It is also found that the transmission quality is subject to the modulation rate change significantly in the mobile environments.
