A Survey on Call Admission Control and Bandwidth Allocation for WiMAX

P.Saravanaselvi, Dr.P.Latha

Wimax (IEEE 802.16) is a broadband technology in which service provider features have the ability to maximize air link utilization and system throughput. To attain Quality of Service (QoS), Call Admission Call schemes (CAC) and Bandwidth allocation mechanisms are important due to random variation of channel conditions and user demands. In this work several bandwidth allocation and CAC mechanisms are analysed based on queue size for the constant bit rate and variable bit rate data types.
