Abstract
.Due to the growing dependence on web for information, entertainment, business, education and real time applications, the demand for high speed broadband wireless systems is increasing rapidly. The IEEE 802.16 (WiMAX) standard has emerged as a solution to meet all these requirements. The IEEE 802.16 has the following advantages; high data rate, wireless access for last mile, point to multipoint communication, high frequency range and QoS for various types of application flows. However the details of packet scheduling mechanisms are left unspecified in the standard. Therefore, we propose a QoS scheduling architecture for efficient bandwidth allocation. Our main goals are to provide delay and bandwidth guarantees for various type of applications and to maintain fairness among various flows.
