So far, WiMAX forum has worked out many specifications of the IEEE 802.16 standard. However, it does not have detailed mechanisms of connection admission control (CAC)、bandwidth request (BR)、bandwidth allocation and scheduling. In this thesis, we propose an admission control scheme called multi-modulation CAC. Rather than most CAC only considering the single modulation environment, our study focused on multi-modulation environment. We use the multi-modulation CAC to improve the traditional CAC can’t work well in multi-modulation environment. With the proposed scheme, base station performs connection admission control to decide whether or not to accept connection requests by number of the remained slot. Finally, we use NS-2 (network simulator version 2) as network simulator and develop an analytical model to evaluate the system performance.
